If the Universe Formed from Nothing, Who Created the Nothing?

it's a well-known saying nothing comes from nothing if we now put this into a galactic context an exciting question arises how could the universe literally come into being from nothing for our terrestrial lives something can only be formed if components exist to build it but where did the material come from that made the hour of birth of the cosmos thus the big bang possible together with you we'd like to take a closer look at this profound topic today what do experts have to say about this central question and can it be answered at all with our current knowledge let's go in search of clues together excited about the groundbreaking discoveries and great mysteries of the universe then remember to subscribe to simply space and click the bell for regular updates on these exciting topics show us with a thumbs up that we can keep you engaged with the content of our videos [Music] the end as the beginning no matter if it's the big rip the big crunch or the big freeze even if theories differ from one another they all end in the same scenario the end of the universe if one follows these hypotheses then one day the last star in the cosmos will burn up afterwards the universe will change into a lightless place of emptiness in that dark apoc gigantic black holes will consume all remaining matter before finally evaporating themselves into a final act of destruction space will expand until even the faint light from the evaporating gravity monsters is too dispersed to interact and the activity of the cosmos will come to a complete halt at least that is a widely held view among scientists while many researchers regard such a process as the final end of our galactic home however some experts recognize in it something completely different namely the beginning of a new universe in fact some researchers are convinced that it was just such a dark cold and empty universe that was the basis of the big bang however before we go deeper into this exciting thesis we should first address another no less exciting question how did the first physical matter actually come into being if we want to explain the emergence of stable matter from atoms or molecules it becomes clear that nothing of the sort existed either during the big bang or in the millennia that followed what we do know is that the first atoms formed from simpler particles as soon as external conditions cooled enough to follow the formation of complex stable matter we also know how these atoms later fused into the stars to form heavy elements however our state of knowledge does not provide any information on how something can be born out of nothing so let's turn the cosmic wheel of time back even further protons and neutrons which together form the nucleus of atoms are considered the first long-lived matter particles in galactic history it's generally assumed that they were created immediately after the big bang before that however no matter existed in the classical sense fortunately physics allows us to trace the timeline back a bit further namely to those processes that took place before the birth of stable matter the planck era within physics that era is called the grand unified theory in detail this theory is based on the fact that at the time of the big bang three of the four known basic physical forces namely the strong the weak and the electromagnetic interaction existed in the form of a single unified force if we penetrate even deeper into this area of speculative physics we see that the physical world consisted of a kind of hodgepodge of short-lived elementary particles among them were quarks the building blocks of protons and electrons the relationship between matter and anti-matter was balanced each type of matter particle had an almost mirror image counterpart made of antimatter if these two particles which differ from each other only in one aspect ever met they destroyed each other but how were these particles formed in this respect the quantum field theory says that even a vacuum considered the prime example of an empty space is in reality bristling with physical activity this occurs in the form of energy fluctuations and can cause particles to appear only to disappear again consequently the vacuum of space-time is also characterized by such processes here too particles seem to appear out of the proverbial void if we stretch our central question further we come to another obstacle how then did space-time come into existence in this respect the planck era impressively demonstrates to us that we eventually come up against insurmountable barriers with our physical theories in detail the conceivably short-lived planck apoc covers the immediate period after the big bang at this point space and time themselves became part of quantum fluctuations the problem comprehensively understand the planck era we need a complete theory of quantum gravity that unifies quantum physics with relativity m theory and loop quantum gravity are considered promising candidates in this regard here ordinary space and time are commonly regarded as emergent consequently what we perceive as space and time is in fact the result of quantum processes occurring at a microscopic level that is incomprehensible to us since our common understanding of space and time is no longer valid in the planck era our classical conception of cause and effect also reaches its limits nevertheless all the theories devoted to this section describes something physical that was happening at that time a kind of quantum precursor of space and time even if our understanding of causality does not apply in the planck era it might be theoretically possible to fathom one component of that era with the help of another however our current theories are not capable of handling this challenging endeavor before the corresponding doctrines are fully developed we cannot make any generally valid statements about the central formation processes of the cosmos at present it remains to be stated that physicists don't know any confirmed cases in which something has formed from nothing creator multiverse or cycles since it is currently impossible for us to decipher the quantum state of the universe at the beginning of the planck era all theories in this regard remain highly speculative some try to explain this central mystery by the influence of a divine creator other less religious explanations see the existence of a multiverse as the most promising approach according to this the cosmos would not be an all-encompassing construct but only a tiny link in an infinite chain of other universes on the other hand there are the cyclic models the corresponding theses are based on the fact that the universe is subject to a constant cycle of destruction and rebirth an exciting approach which has a prominent supporter with the nobel prize winner roger penrose the british physicist once led the theory of the conformal cyclic cosmology into the field if one follows the explanations of this expert there are striking mathematical parallels between the big bang and the distant end of the universe in fact these two states are even identical when they are brought to their limits this circumstance led penrose to a hypothesis which seems extremely paradoxical it was the complete absence of matter which produced all matter in the cosmos from this point of view the big bang therefore originates from something which comes closest to the ominous nothing namely what remains when the matter of a universe has been annihilated by black holes that have subsequently decayed into photons but how is it possible that a cold empty universe corresponds to a hot dense universe from a mathematical point of view the answer to this question lies in a sophisticated mathematical procedure called conformal scaling this is a geometric transformation that changes the size of an object but leaves its shape untouched and indeed in this way it's impossible to scale the states of the universe so that the shapes of their space times coincide in other words the hot dense state exists because of the cold empty state thus the end of an expanding cosmos is eventually followed by a new big bang the search for the nothing let's assume that penrose's controversial theory is confirmed one day even in that case we still wouldn't have an answer to the question of how something can come from nothing where does physical reality come from how is the cycle system of the universe formed why does anything exist at all and not nothing can there be such a thing as nothing at all if by this is meant the absence of everything how can something exist that does not exist as you can see it doesn't take long before some philosophical questions creep into this exciting topic for our video today however we would like to stay in the realm of physics for once so what does science have to say about the possible background of the cycles one approach says that there could be no physical explanation for this at all or it's about an endless change of repeating cycles where the initial quantum state of every cosmos conditions the properties of the following universe furthermore it's conceivable that only a single cycle exists with the beginning of the cosmic cycle being defined by a property of its end who knows if we will ever get an answer to the fundamental questions of the universe but is it not just this great uncertainty that makes the topic so compelling time and again researchers turn their gaze to remote areas of space to gain new insights into our galactic environment however investigating remote regions of the cosmos isn't always necessary because sometimes they come to us for example smaller galactic objects regularly enter the earth's atmosphere serving up some important information about themselves and their origins on a silver platter such an event which is by no means unusual is thought to have been recorded in papua new guinea a few years ago what's mysterious about this instance is that the discovery was hidden from the interested public all over the world the secret meteor the year is 2014 when the sky over papua new guinea briefly begins to glow at that time on january 8th an object entered the earth's atmosphere at an insane speed and subsequently burned up before that the cosmic projectile had moved through space at a speed of more than 120 000 miles per hour a really impressive speed clearly exceeding the average speed of classic meteorites spinning past our domestic solar system it was this extraordinary speed that provided the experts with a revealing insight into the origin of the meteorite in a study conducted in 2019 experts concluded that the compact meteor just under two feet in diameter was 99 percent likely to have originated outside the solar system it was possibly a structure that came from the deepest reaches of an alien planetary system there's a thesis that the meteor originated in the dense disk of the milky way despite these remarkable findings and theories however the results of the scientific study were meticulously kept under wraps for a long time the fact that we are only now learning about this exciting discovery is primarily due to the fact that some of the data needed to verify the calculations were classified as top secret by the us government since the interstellar trajectory of the object is now considered confirmed it retroactively advances to become the first interstellar structure ever detected in our solar system this title previously belonged to the object omua mua which has posed great mysteries to researchers since its discovery in october 2017 but more on that later amir suraj a theoretical astrophysicist at the renowned harvard university and lead author of the study now intends to publish the results of his work in a timely manner this will make it possible for the international scientific community to extend the analyses since the meteor burned up over the south pacific at the time it's conceivable that some of its fragments landed in the sea it's therefore possible that some fragments of the galactic projectile still lie dormant at the bottom of the ocean waiting to be tracked down and studied although recovering this interstellar debris is like the proverbial search for a needle in a haystack suraj is already in intensive talks with other experts to discuss just such an expedition flying mystery before the true background on the origin of the 2014 meteor was revealed omuamua was considered the first object observed within the solar system to be classified as interstellar the groundbreaking discovery of the craft was made possible with the help of the pan-starrs telescope in hawaii where it was added to the star charts on october 19th 2017. however by the time experts became aware of the existence of the unusual entity it was already on its way back to interstellar space once again astronomers describe interstellar objects as those bodies that are located in interstellar space or in other words the space far from a star and are not gravitationally bound to a particular parent star however the objects in question may temporarily pass near a star during their journey through space after scientists learned of the existence of our interstellar visitor it raised a fundamental question what exactly is omuamua all about the first analysis of its orbital properties suggested that we are dealing with a classic comic however it wasn't long before this initial hypothesis was thrown into doubt because omuamua does not have a characteristic tail what we do know is that the object described the apex of its orbit on september 9th 2017. at that very moment the structure was temporarily moving around the sun at over 50 miles per second approaching within about 20 million miles of our central host star a little over a month later omuamua then went head to toe with our blue home planet when it passed earth at a closest distance of about 15 million miles since then the interstellar body has been on course for the constellation pegasus in addition to all these objective findings about the trajectory of the object there were also some unexpected observations things researchers still cannot explain exactly among them for example is the fact that omuamua slowed down somewhat less after its solar passage than the experts had predicted this circumstance cannot be explained by the pure influence of gravity at first it was speculated that the additional acceleration could be attributed to the outgassing of volatile components such an outgassing caused by the proximity to the sun would have led in all probability to a drastic change of rotation in fact however this was not detected to gain further insight into the characteristics of this flying mystery omuamua was observed by numerous modern telescopes during the analyses it became clear that the object undergoes dramatic fluctuations in brightness a characteristic that suggests that the structure has the shape of an oversized cigar however the analysis of the photometric data collected was not sufficient to explain the unusually strong brightness fluctuations with a corresponding rotation speed thus it seems that omuamua does not rotate around one of its main axes during its flight but rather staggers through space it's likely the object already showed this motion pattern when it left its home system all these unexpected observations and characteristics finally led to a central question is it possible that omuamua has no natural origin but was artificially created an alien spacecraft this controversial speculation was also fueled by the fact that no dust particles could be identified in the immediate vicinity of the ominous body this in turn leads to the assumption that omuamua does not contain any water and possibly consists entirely of metal since the surface of the object was exposed to an incessant bombardment of cosmic rays during its billion-year journey the experts assume a comparatively low reflectivity assuming that the albedo is 0.04 the mean diameter of the missile would be about 700 feet in november 2018 astrophysicists abby loeb and shmuel bialy hit the headlines when they tried to justify the absence of dust and orbital deviation with an unconventional hypothesis thus the corresponding observations could well be explained by an extremely thin large surface area body that was deflected from its ancestral orbit under the influence of the sun's radiation pressure possibly so the two israeli experts think o muammua is an extraterrestrial solar sail sent by an intelligent civilization to research our solar system an unusual assumption which was not categorically rejected by other researchers in fact in december 2017 some researchers decided to take a closer look at aomoamua as part of the breakthrough listen research project to this end the entity was analyzed by the radio telescope at the greenbank observatory in west virginia the goal of this endeavor was to register possible signals of artificial origin although it was considered extremely unlikely that we'd encounter radio signatures of an extraterrestrial species in the run-up to the work the scientists nevertheless saw the investigation of omuamua as a worthwhile unique opportunity over a period of 14 days the interstellar object was analyzed in different frequency ranges however the evaluation brought the sobering realization that no evidence of an artificial background could be found future investigations to reveal the true background of our mysterious visitor a direct investigation seems most promising but how do you intercept a craft traveling away from us at more than 15 miles per second it would be virtually impossible for conventional space probes to reach omuamua in order to get to the bottom of this exciting mystery one day new approaches would have to be taken one such concept is based on a literally explosive approach an unmanned spacecraft could be ejected from our solar system by igniting a solid fuel engine once such technology is fully developed it would be possible to reach omuamua within 16 years of the launch of the terrestrial spacecraft however patience will be required before this can happen those who do not believe in an artificial origin of the object sometimes suspect that it could be the fragment of a pluto-like exoplanet according to this view omua mua would consist mainly of frozen nitrogen however the interstellar structure would have already lost most of its original mass during its journey large parts of the nitrogen ice melted so that the once clearly more massive body took on a flat form black holes are not only one of the most impressive but also one of the most puzzling entities the cosmos has to offer while experts have successfully deciphered many of the fundamental characteristics of these gravity monsters in recent years one question has remained unanswered how are supermassive black holes formed while we now know that the particularly large representatives of this class of objects grace the centers of nearly all galaxies how they themselves are created is still a galactic mystery a breathtaking discovery could however bring some light into the cosmic darkness for the first time researchers have tracked down the precursor of a supermassive black hole in today's video you'll find out what this sensational discovery is all about and what puzzles still need to be solved in the future mysterious omnivores whether it's matter radiation or any other form of information anything that winds up in the grip of a black hole is irretrievably lost this is the fundamental characteristic that nothing that has passed the event horizon of a black hole can leave it again a breathtaking as well as frightening property which is due to the incomparably strong gravitational force of black holes this in turn is created by the extreme compactness of the objects if a black hole possessed the same mass as our earth it would not be much larger than a speck of dust however a look at the astronomical reality shows that the gravity monsters are significantly more massive than our blue home planet according to this there are black holes in the gigantic expanses of the cosmos that exceed the mass of our sun by a factor of millions or even billions in principle however all black holes are not created equal the easiest to understand are the basic mechanisms of so-called stellar black holes as the name of this subclass suggests these are objects that emerge from stars when a star of a certain size has reached the final stage of its existence it ejects its outer layers in a supernova what remains is the stellar core which collapses due to its own gravitational pressure to an incomparably compact structure a stellar black hole as mentioned at the beginning black holes devour everything that crosses their galactic orbit in view of this fact one might think that the mass monsters destroy everything that approaches them up to a distance of some light years however in truth the exact opposite is the case it's considered certain now that supermassive black holes play fundamental roles in the development of galaxies in fact outside their event horizons these gravity monsters behave just like conventional mass bodies therefore it's easily possible for another celestial body to rotate on a stable orbit around a black hole a groundbreaking discovery unfortunately what is true for stellar black holes does not translate seamlessly to their supermassive counterparts while experts can trace the formation of stellar black holes in detail the birth of their significantly more massive counterparts has always resembled a formidable mystery to get one step closer to solving this cosmic mystery data and observations are needed above all and in fact astronomers recently scored a bullseye in this regard with the scientific designation gnz 7q experts suspect that the detected object could indeed be the precursor of a supermassive black hole in detail the sensational discovery was recorded in a galaxy from the early days of the universe and possibly represents the missing piece of the puzzle within the star-forming galaxies and the first supermassive black holes of the cosmos observations in the ultraviolet and infrared spectra showed that a black hole is growing inside the galaxy under study until now the most distant objects were either so-called starburst galaxies known for their enormous star formation rate or galaxies with incredibly active supermassive black holes that outshine the light of all surrounding stars so called quasars in the case of gnz 7q at first glance it appears to be a classic starburst galaxy however the information gathered during the in-depth investigation suggests that the central black hole is in the process of transforming into a quasar in this regard analysis of the object across the electromagnetic spectrum is an exact agreement with predictions from theoretical simulations in detail the corresponding galaxy produces about 1600 sun-like stars per year exceeding the corresponding formation rate of our local milky way galaxy many times over the emitted uv light matches the characteristic accretion disk that typically surrounds a supermassive black hole however no x-ray emission has yet been detected in these central regions this circumstance suggests the conclusion that the future supermassive black hole is currently still completely enveloped in gas and dust such a scenario has so far only been predicted in computer simulations never directly observed accordingly gnz 7q is considered a promising candidate when it comes to the question of the missing link between starburst galaxies and quasars astronomers plan to study the structure in the future using the james webb space telescope if everything goes according to plan the complex instrument will begin its scientific service in a few months and provide us with a previously unknown insight into the greatest mysteries of the cosmos sagittarius a star while it's now considered certain that the galaxies of the universe would not exist in this form without the participation of their central black holes how exactly the formation of the gravity monsters is related to the evolution of planets stars etc is not known what depending on the estimation is true for most or even for all spiral galaxies is of course also true for our milky way that is in the heart of our home galaxy there is a black hole which effortlessly dwarfs the usual magnitudes of the solar system sagittarius a star as the object is scientifically called has an incredible 4.3 million solar masses situated in the constellation sagittarius a distance of about 26 670 light years gapes between the monstrous structure and our blue home planet due to its extreme compactness the diameter of the event horizon is about 13 million miles recent investigations indicate that the black hole was active a long time ago which means that our milky way could have been an active galaxy once too back in the early 1930s u.s physicist carl jansky came across an unusually intense source of radio waves in the constellation sagittarius more than four decades passed before the ominous object responsible for it was identified however using the interferometer at the national radio astronomy observatory in virginia researchers robert brown and bruce balik succeeded in adding sagittarius a star to the star charts in 1974 however the fact that it's most likely a super massive black hole was not proven until a series of observations over several years that began in the 1990s later lead researchers reinhard ganzel and andrea guez would be honored for their discovery with the nobel prize in physics investigation of the region in question soon yielded the realization that some remarkable spectacles were taking place in the immediate vicinity of sagittarius a star these included the observation of a star approaching the central black hole to within 10 billion miles experts later discovered that the 15 solar mass celestial body was rotating around the gravity monster at speeds of over 3000 miles per second in the course of the following years it became clear that the glistening bright body is in the best company the central mass monster is orbited by a whole series of other stars since these objects sometimes come dangerously close to the black hole on their orbits they could belong to the so-called squishar class this currently exists only in theory and describes a type of star that is strongly squeezed as a result of enormous tidal forces no less exciting was the discovery and observation of the g objects one of them the gas cloud g2 approached sagittarius a star by up to 15 billion miles thereupon the cloud was practically torn apart and brightly illuminated by the radiation of surrounding stars so far we know of six such g objects moving in orbit in the realms of our central black hole on average these objects have an extension of about 100 astronomical units the length of the astronomical unit corresponds to the approximate average distance between the earth and the sun and can be estimated at about 90 million miles if the g objects come into contact with sagittarius a star during their journey they expand even further as a result of the forces acting on them while the black hole at the heart of the milky way is often the focus of scientific interest we should not forget that it's by no means the only representative of this class of objects in our home galaxy at the beginning of 2005 strong outbursts of brightness were registered in the vicinity of sagittarius a star suggesting that there are 10 000 to 20 000 other black holes in its vicinity their supermassive counterpart serves as a gravitational fixed point for these gravity monsters this finding also fuels a theory that has been the subject of controversial debate for several years the corresponding thesis is based on the fact that large central black holes are regularly supplied with material by their smaller counterparts in detail this galactic feeding is supposed to happen as follows the small black holes bind stars in the outer regions of the milky way which lead them on their orbit to the immediate vicinity of sagittarius a star once there some stars are finally detached and consumed by the elemental forces of the supermassive object the cosmos is known above all for two characteristics its exuberant diversity and the elemental forces at work within it when a massive star has reached the last stage of its natural span of existence it seals its own end with an explosive farewell a so-called supernova the findings that experts obtain in the course of studying these stellar deaths regularly bring home to us the fascinating uniqueness of such spectacles in today's video we'll show you how researchers recently succeeded in identifying a new nova record holder and the sheer incredible emissions that were released during the process when stars die once a massive star enters the final chapter of its cosmic life it's time for a brutal radiant farewell the process of supernova refers to the short-lived intense illumination of a star that comes from a gigantic explosion how extreme these stellar deaths can be becomes clear to us if we keep in mind that the luminosity of the celestial body can increase billions of times in the course of a supernova sometimes the star briefly shines even as brightly as a full-grown galaxy within a few seconds about one foe of observable energy is released to understand how this value fits into the overall galactic context it's worth taking a look at our sun if our host star would have its current luminosity during its whole lifetime it would release about 1.2 fo of energy as a reminder it's estimated that the sun's own fuel is sufficient for a total of 10 to 13 billion years basically there are two basic mechanisms that can cause stars to go supernova on the one hand there are those stars whose initial mass is more than eight solar masses if the nuclear fuel of the celestial body is completely used up its life ends in the course of a so-called type ii explosion after the hydrogen in the stellar core has fused into helium the internal pressure of the star also drops dramatically as a result the celestial body collapses under the influence of its own gravity the resulting increase in temperature and density in turn sets another fusion stage in motion the three alpha process in this process three helium nuclei are converted into carbon by nuclear fusion reactions inside stars emitting gamma radiation this process repeats a few times with carbon burning to form neon finally after a series of further fusion processes the time comes when the stellar burning processes come to a complete halt as a result the hydrostatic equilibrium of the star is severely affected the oppositely acting gravitational pressure literally presses the celestial body into itself as a result the outer layers also fall towards the center where they finally come into contact with the hottest part of the star the iron nickel core however the incoming shock wave is thrown back by this massive dense stellar heart setting off the classic stellar collapse supernova as the shock wave now bounces outward what remains of the progenitor star after this glistening explosion is decided by the remaining mass which collapses usually stellar death ends in the formation of a neutron star which typically weighs between 1.2 and 2.0 solar masses due to their extreme compactness these stellar remnants have radii of only six to seven miles moreover these objects are the densest known formations without an event horizon besides their strong magnetic fields neutron stars are known for one special property their insane intrinsic rotation speed the current record holder in this category achieves an incredible 716 revolutions per second this corresponds to almost a quarter of the speed of light however it's also possible that the death of the star will result in the birth of a stellar black hole these equally fascinating and frightening formations are created when the star's core collapses into an incomparably compact body due to its gravitational pressure the gravity generated by this compactness is so strong that black holes become galactic omnivores nothing that has passed the event horizon of a black hole can cross it again from the inside out when exactly the progenitor star meets its prescribed fate is defined by its initial mass the heavier the star the shorter its cosmic life expectancy type 1a supernovae as mentioned earlier in addition to this well-known basic mechanism another exists that can transform a star into a supernova while the type 2 explosion is still due to the drying up of stellar fuel and the associated consequences a type 1a supernova involves two celestial bodies at once this double star system consists of a white dwarf and its companion as a reminder white dwarfs are small compact old stars with very low luminosity over the years the white dwarf accretes more and more gas from the expanding envelope of its companion as a result of this transfer of material several nova outbursts can be set in motion a term that should not be confused with the term supernova anova describes a burst of brightness in a binary that originates from an explosive ignition of hydrogen burning on the surface of a white dwarf in the course of these outbursts the hydrogen of the ingested gas thus fuses until the white dwarf has enriched its core with enormous amounts of contaminated carbon further combustion and accretion processes caused the stellar core which now resembles an oversized diamond to become steadily more unstable once the limiting mass is reached the entire carbon supply is burned to nickel and iron within fractions of a second which means that it detonates as a type 1a supernova unlike a core collapse supernova however no compact objects such as a neutron star or stellar black hole remains the matter of the dying white dwarf is completely catapulted into the gigantic expanses of space also the companion star is not unaffected by this primordial event it transforms into a so-called runaway star due to the high orbital velocity with which it once orbited the white dwarf before it literally flies away violent nova eruption [Music] now that we have taken a look at the two best known basic types of supernovae it's time to take a look at an exciting discovery that researchers made just a short time ago in detail the researchers were dealing with the precursor of a type 1a supernova the system that became the focus of scientific interest is called rs ofiyuki as the researchers from the max planck institute in munich discovered during their investigation the nova outbursts were accompanied by an unusually intense emission of gamma rays about five thousand light years from our blue home planet a white dwarf in the epinymous constellation ophiuchus incessantly accretes material from its companion a red giant star as briefly described earlier the absorption of hydrogen gas on the surface of the white dwarf sometimes leads to overheating that sets off violent thermonuclear explosions these violent events usually follow a fixed cycle in the case of rs ofiyuki about 15 years elapsed between nova eruptions finally the most recent nova observed by experts was accompanied by an unexpectedly high gamma-ray burst in detail the emission which was registered and analyzed with the help of the two magic telescopes on the canary islands reached an incredible value of 250 giga electron volts this is one of the most intense gamma-ray bursts ever observed by astronomers the explosion produced shock waves that accelerated particles to near the speed of light based on their collected data the scientists concluded that the gamma rays originate in energetic protons the nuclei of hydrogen atoms in other words nova eruptions are also sources of cosmic rays this means a high-energy particle radiation which is mainly composed of protons but also of electrons and completely ionized atoms the corresponding particles move through the gigantic expanses of the cosmos at almost the speed of light compared to the enormous shock fronts generated by supernovae however the forces released by nova outbursts are significantly less intense one day rs offiyuki will also be torn apart as part of a type 1a supernova however a look at the expert's next discovery shows that not all objects want to follow the supposedly fixed rules of the cosmos stellar death throes when a massive star goes supernova it shines brighter than full-grown galaxies for a few days before rapidly losing luminosity afterwards a supposedly fixed scheme which went completely ad absurdum in the case of the object ipft14hls astronomers like stan woosley who dedicated themselves to the investigation of the structure called this simply bizarre the background it seems as if the star in question simply does not want to die originally discovered in september 2014 the stellar explosion was initially thought to be a perfectly ordinary supernova however when an attentive intern sifted through the collected data again five months later he came across a puzzling detail the supernova first became fainter as expected only then to shine brighter again afterwards even more puzzling is the fact that this was not a one-time phenomenon but a reoccurring one over an observation period of two years this interplay of dimming and intensification was registered five times the analysis of the light spectrum paints a clear picture and perfectly matches the basic characteristics of supernovae ruling out any other event never before have experts been confronted with a supernova lasting years normally dying stars go out completely after about three months but that's not all a review of archival images showed that another stellar explosion had occurred at exactly the same location in 1954 but had been overlooked at the time the question of what is behind this supernova hiccup is still the subject of research now we want your opinion what do you think about the stellar explosion

outer space then take a look at the other videos on our channel which we have linked for you here in the credits thanks for your interest take care and we'll see you next time
