25 Crazy Facts About Black Holes

[Music] number 25 black holes effect time just as a clock runs a bit slower closer to sea-level then upon a space station clocks would run really slow near black holes it all has to do with gravity number 24 they can be infinitely big or so some theories state but without a doubt when it comes to something of this nature there are scientists on both sides of the fence number 23 the nearest black hole to earth is 1600 light-years away our galaxy is covered in black holes but the one most likely to destroy our measly planet is still well beyond our solar system's borders number 22 stay away from the event horizon the event horizon as it's called in physics is the border of the black hole it's the point of no return before that point you can still escape after that point not a chance number 21 there's a massive black hole at the center of the Milky Way galaxy it's 30,000 light years away and is over 30 million times as massive as our Sun number 20 black holes eventually evaporate although common knowledge states that nothing can escape a black hole at least one thing does radiation according to some scientists as black holes emit radiation they're losing mass this process has the potential to eventually killed a black hole number 19 black holes are not infinitely small at some point the collapsing core of a black hole becomes even smaller than an atom or an electron and eventually it reaches its Planck length a quantum size limit that makes it barely measurable number 18 black holes are not funnel-shaped in most textbooks you'll probably see black holes that look like funnels this is because they're being Illustrated from the perspective of gravity wells in reality they're probably more spherical than anything number 17 black hole spin when the core of a star collapses the star rotates faster and faster and becomes smaller and smaller when it reaches the point where it doesn't have enough mass to become a black hole it gets squeezed together to form a neutron star and continues to spin rapidly the same applies to the black holes even when the black hole shrinks to its Planck length it continues to spin rapidly number 16 things get weird when they get near a black hole black holes have the capacity to distort space itself and as they continue to spin that distortion gets distorted it's an infinite regression of distortions number 15 getting near a black hole can kill you in horrible ways although it seems obvious that a black hole is incompatible with life most people think they would just get crushed this isn't necessarily the case you would most likely get stretched to death because whatever part of your body reaches the event horizon first will experience significantly more gravity number 14 black holes aren't always black although they're known for their blackness as we said earlier they actually do emit electromagnetic radiation number 13 black holes aren't necessarily only destructive of course in most circumstances they probably would be but there have been numerous theories studies and suggestions put forth that black holes can actually be harnessed for things like power and space travel number 12 black holes can get really big although we just talked about how small they are black holes get larger and larger as they collide with other black holes allowing their size to increase with every collision number 11 there are different kinds of black holes modern astronomers have shown that black holes actually come in different variations they're spinning black holes electrical black holes and spinning electrical black holes the type of black hole depends on the amount of energy it puts out when it distorts space number 10 it was not Albert Einstein that discovered black holes Albert Einstein only revived the theory of black holes in 1916 long before then 1783 scientists named John Mitchell actually developed the theory after he wondered whether a gravitational force could be so strong that even light particles couldn't escape number 9 black holes can be very dense to have enough gravity to pull even light into itself a black hole has to contain an incredible amount of mass in an extremely small space this means the black holes must have a mass of about 10 to 30 billion times that of the Sun number eight black holes are noisy okay although the vacuum of space doesn't really allow for sound waves if you listen with special instruments you would hear a staticky sound when a black hole pulls something in its event horizon supercharges the speed of particles close to the speed of light which produces the sound number seven nothing can escape the pull of the black hole okay that sounds obvious by this point but we would like to introduce the caveat unless it can move faster than the speed of light number six black holes might create elements that make life possible researchers say the black holes create elements as they break down matter into subatomic particles these particles have the ability to create elements heavier than helium such as iron and carbon as well as many others that are essential to the formation of life number five white holes black holes are best known for sucking up everything that gets near their event horizons once mass gets into a black hole it gets squashed so hard that its individual components become compressed and eventually break down into subatomic particles some scientists theorize that the matter is then injected in a phenomenon known as a white hole number for any matter can become a black hole technically speaking stars aren't the only things that can become black holes if your car keys were shrunk down to an infinitesimally small point and still retained all of their mass their density would reach astronomical levels which would make the force of their gravity ridiculously strong number three the laws of physics break down at the center of a black hole according to theories matter within a black hole is crushed to infinite density and space and time cease to exist when this happens the law of physics break down because it's not really humanly possible to conceive of anything with zero volume and infinite density number two there is no tunnel at the center of a black hole as we said earlier contrary to popular belief that there's a tunnel in the middle of every black hole all that exists at the center of a black hole is a massive amount of matter compressed infinitely and number one black holes determine the number of stars according to some scientists the number of stars in the universe is limited by the number of black holes this is due to the way they affect gas clouds an element formation within the parts of the universe known to produce new stars if you liked the video you just
