How The Universe Works - The Dr. binocs Show | 25 Minutes Animated Compilation Of The Universe

whoa it all started with the Big Bang it all started with the Big Bang Bang yes little kitty everything we look around right from the grain of sand to trees to mountains earth galaxies and the universe it was all formed after a Big Bang still confused friends so in today's episode let us learn about the beginning of our universe and shed some light on an interesting question that is what is the Big Bang Theory zoom in the universe it has fascinated humanity so much that cosmologists have devoted their entire lives gazing into the space to find the answer to the most important question about the universe and how it evolved its actions in the past present and future and how it came into existence in the first place sorry I got a bit carried away a lot of scientists assume that the universe began nearly 13.7 billion years ago with a massive explosion of an extremely hot bubble that was thousands of times smaller than a pinhead this idea at first one jokingly referred to as the Big Bang but as the time progressed and evidence piled up the concept and the name stuck with the scientific community after the explosion the universe that we know today was born and with it time space and matter came into existence and it all happened in a fraction of a second yes friends in just a matter of seconds the universe grew from smaller than a single atom to bigger than a galaxy and it kept on expanding at a phenomenal rate and continues to grow even today as the universe cooled down the energy converted into particles of matter and antimatter these two opposite types of particles fought hard and largely destroyed each other but some brave matter managed to survive please note that just one second has gone by so far since the beginning of everything and the universe had already grown into 100 billion kilometres and is cold enough to form most stable particles called protons and neutrons over the next three minutes the temperature fell below 1 billion degrees Celsius now the universe got more cold to allow the protons and neutrons to come together and form its first atom the hydrogen after millions of years when the hydrogen gas clumped together and gravity started to put it under pressure stars and galaxies began to form their radiation began dissolving the stable hydrogen gas into plasma that allowed visible light to pass and finally there was light serve your time did you know the single super concentrated point or bubble which later became the universe before the Big Bang was called the primeval atom or the cosmic egg also in one of the possible scenarios for the ultimate fate of the universe known as the Big Crunch the universe will eventually stop expanding and start collapsing in on itself then however another Big Bang might happen hope you enjoyed today's episode until next time it's me dr. by NOx zooming out oh never mind [Music] coming soon guardians of the Milky Way [Music] Milky Way isn't like this kitty I [Music] understand your confusion little kitty but Milky Way isn't a fantasy land full of making products but a real thing and what is that so friends in today's episode let us launch ourselves outside the atmosphere and into space to explore an essential part of a universe called the Milky Way zooming in the wasps nests of the universe you will find a hazy spiral ring of white light that looks like milk spilled across the sky the spiral ring isn't milk of course but a galaxy to which the ancient Romans call the band violet Hill which means milky Road or Milky Way yes my friends the Milky Way is a galaxy and what is a galaxy it is a large cluster of over hundred billion stars planets gas and dust all assembled and held together by gravity even a solar system that includes our very own earth neighboring planets and Sun is a part of this galaxy we called the Milky Way astronomers believe that our Milky Way galaxy is approximately 13 point 6 billion years old and it is so big that light takes hundred thousand years to cross from one site to the other the center of the Milky Way galaxy is tough to see due to clouds of gas and dust that blocks our view but scientists believe that it is a supermassive black hole called Sagittarius a star that swallows anything crossing it and it is very much possible that this black hole may be the source of gravity that holds the galaxies together much like many good things the Milky Way will meet its end as well yes my dear friends it is predicted that the Milky Way has 4 billion years to live as after that it will collide with a giant spiral neighbor Andromeda yes this isn't any science fiction story but a reality currently Andromeda and the Milky Way are about 2.5 million light years apart fueled by gravity the two galaxies are rushing towards each other with a speed of nearly 400 and 2,000 kilometers per hour but don't worry friends because even at that speed they won't meet for another for billion years and with the collision these galaxies will merge together to form another giant elliptical shaped galaxy trivia time did you know the Milky Way is a part of a cluster of galaxies near each other that is called a local group made of about 30 galaxies yes and the three largest galaxies in our local group is the Andromeda galaxy the Milky Way and the Triangulum galaxy the other galaxies are much smaller in size and two of them can be seen with the naked eye from countries south of the Equator also did you know our Milky Way is as old as the universe itself yes the age of the universe is about 13.7 billion years and our Milky Way has been around for about thirteen point six billion of those years you know what they say old is gold hope you enjoyed today's episode until next time it's me dr. by NOx zooming out ah never mind hey friends don't you just love a warm sunny day from afar it seems like the Sun is equally bright no matter where you look from but that is not the case if you look closely at the surface of the Sun you will see some areas darker than the others and sometimes you might even see sudden bursts of brightness on the surface of the Sun these are what we call sunspots and solar flares let me tell you something more about them come on zoom in the Sun is a dense cloud of bright and hot gases it holds immense pressure within itself and sometimes this pressure becomes too much so the Sun has to let go of some of its energy when the Sun does this some areas on the surface become even brighter these bright areas are called solar flares and they disappear very suddenly solar flares usually take place around the active parts of the Sun surface such as the sunspots these are areas of high magnetic activity on the surface of the Sun although they produce light it is not as bright as the area around it so the sunspot appears darker they are actually cooler than the rest of the Sun when a solar flare occurs it also releases different kinds of energy particles like electromagnetic energy electrons ions etc these particles usually reach the earth in around a day or two but don't worry they don't harm us because we are protected by the atmosphere of the earth and it's electromagnetic field the sunspots were even used in ancient times to figure out that the Sun rotates when people looked at the Sun they noticed the sports change and realize that the Sun must be rotating triviatime Aurora's popularly known as the Northern Lights are caused by the solar wind hitting the Earth's atmosphere sunspots were observed as far back as 364 BC by astronomers in ancient China now wasn't all this amazing who knew there is so much going on on the surface of the Sun as they say don't judge a book by it's cover who knows what is going on under such simple looking things so friends until next time keep your binoculars out and your eyes open who knows what you might find this is me zooming out [Music] what do you call the death of a star well that's an easy one it's called a supernova know what supernova kitty oh you've never heard of that word before kitty oh well there's no need to worry my dear one doctor buy notes is here so let me grab this opportunity and teach you and our friends out there above this natural phenomenon called supernova zoom in Stars they come in all colors shapes and sizes like the blue giant red giant red supergiant even our Sun is a type of star called g2v yellow dwarf but despite these differences most of them meet the end with a supernova so what is a supernova well a supernova is a massive explosion that takes place at the end of a star's life cycle in other words it is the death of a star but the vital question is what causes this explosion aka a supernova well a supernova occurs when there is a change in the core or center of a star this change can happen in two different forms with both resulting in a supernova first let us look at the type of supernova that happens in the binary star systems that consists of two stars orbiting around their common center of mass during the process one of the stars a carbon oxygen white storm takes matter from its partner star eventually the white dwarf gathers so much matter that makes it difficult to digest and causes the star to blast resulting in a supernova the other type of supernova happens at the end of a single stars lifetime as the star runs out of nuclear fuel some of its mass flows into the core eventually the center part of the star is so heavy that it cannot withstand its own gravitational force and it becomes like a nuclear time bomb finally the core collapses and all the matter and radiation blast out which results in the monstrous eruption we call a supernova but fortunately not all stars end with a supernova even our own Sun is a single star but it does not have enough mass to become a supernova or else it would have been a significant threat to a solar system that includes our earth trivia time did you know a supernova burns for only a short duration but it can tell scientists a lot about the universe yes one kind of supernova has revealed to scientists that we live in an expanding universe one that is growing at an ever-increasing rate scientists also have discovered that supernovae play a vital role in spreading elements all around the universe yes when the star bursts it shoots elements and debris into space many of the elements we find here on earth are made in the core of stars these elements travel on to form new stars planets everything else in the universe hope you enjoyed today's episode until next time it's me dr. by NOx zooming out ah never mind ooh that looks like a black hole oh no I shouldn't be here but I'm not going to go before I tell you about black holes come with me zoo in a black hole is formed when the core of a star collapses and the star explodes therefore we can say that a black hole is born when a star dies when a massive star reaches the end of its life its go starts running out of fuel the core is no longer able to hold the star back resulting in its collapse this gives birth to a mini black hole with gravity running wild inside it the black hole starts eating up everything that's left of the star and it all happens in milliseconds even before the stock and realize what's happening to it it explodes the explosion releases a tremendous amount of energy even more than our Sun can produce in its entire lifetime whoa isn't that crazy hmm let me tell you a secret you could turn into a black hole yep the computer you're using me or anything around you that has matter has a small child radius also called the gravitational radius which is the radius of the tiny sphere into which if a mass of an object is compressed to fit in its escape speed would be equal to the speed of light which is wait much but chances of you turning into a black hole are rare because of the tiny size of your swords child radius stuff that gets too close to a black hole gets sucked in because of the super humongous gravitational pull so nothing can escape a black hole not even light hey have you ever wondered what would happen if two black holes collided chances are that they might become one big massive black hole or probably put up a fight and send one of them hurtling away the bigger the Lightyear triviatime time runs differently dear and inside a black hole and this has a lot to do with gravity the nearest black hole to earth is 1600 light-years away don't worry friends that's too long a time but you make sure you don't take that long to tune in next time for more fun facts this is me zooming out run faster little kitty or else we will miss the bus oh no goodness me we missed it oh well no worries little kitty we will go for the picnic next time but I wish there was still a way to reach their own time maybe a shortcut maybe a tunnel or maybe a wormhole oh yes little kitty a wormhole hey friends I'm sure you must have heard the term bum old before but do you know what it exactly is if not then don't you worry my curious friends fasten your seat belts because in today's episode littles travel into this mysterious passage in the universe we call the wormhole and explore its deepest secrets zoom in so what is a woman to understand what a wormhole is first you need to understand what a black hole is because a woman is actually two black holes that are connected like a tunnel between two places in space by going through the wormhole you could travel immense distances across space faster than the speed of light even if the two ends of the wormhole were very far apart yes my friends you could quickly go on a day trip from one planet in a distant galaxy to another planet imagine if you had one end of the wormhole at home and the other end at school then you could just step through the wormhole at home and arrive in the class without worrying about getting late unless you are too lazy to get out of bed so a formal could be a cool thing to have around but the problem is as far as we know there are no vamos this in our universe and the only place we can find them are on paper yes my friends we haven't found any evidence of them existing and we don't have a clue about how they are formed however the existence of bamos is not restricted by a current theories of the universe so we can say that they do exist in theory you might be available at theory of general relativity published by famous scientist Albert Einstein in the year 1900 and 16 in explains gravity which is what keeps us on earth and keeps the earth orbiting the Sun this theory also mathematically describes the wormholes so how to understand bamos through theory firstly we need to know about something called space-time we often imagine space-time as a flat stretchy fabric sheet everything you see around in our universe exists on this hypothetical space-time fabric sheet by imagining about the fabric sheet we are envisioning something called a two-dimensional surface a planet wandering on the sheet can choose two kinds of movement going front and back or going left and right but in reality space is three-dimensional which means that planets can also jump up and down in fact there's also a fourth dimension and that is time and by putting all the dimensions together you get what we call space-time now let's get back to wormholes imagine we want to travel from one place to another on this imaginary space-time fabric sheet say from Earth to a faraway planet even with the fastest rocket this he could take thousands of light years to complete so this theory proposes that what if we could fold over the fabric so that our health and the faraway planet line up and then make a hole connecting the two layers of space-time then we could have a shortcut tunnel to get to the planet without having to take the longest route even though a wormhole is just a theory I hope some day it will turn into a reality so that we could explore the wonders of our enormous universe trivia time did you know the wormhole is nicknamed as the einstein-rosen bridge yes that's because in 1935 Einstein and physicist Nathan Rosen used the theory of general relativity to elaborate on the idea proposing the existence of bridges through space-time hope you enjoyed today's episode until next time it's me talk - bye knocks zooming out ah never mind
