00:06 Ohhh! That looks like a black hole.
00:10 Oh no, I shouldn’t be here.
00:13 But, I am not gonna go before I tell you about Black Holes.
00:18 Come with me, Zoom in!
00:22 A black hole is formed when the core of a star collapses and the star explodes.
00:28 Therefore, we can say that a black hole is born..
00:33 ..when a star dies.
00:36 When a massive star reaches the end of its life,..
00:40 ..it’s core starts running out of fuel.
00:43 The core is no longer able to hold the star back, resulting in it’s collapse.
00:50 This gives birth to a mini black hole.
00:54 With gravity running wild inside it,..
00:57 ..the black hole starts eating up everything that’s left of the star.
01:02 And, it all happens in mili-seconds,..
01:05 ..even before the star can realise what’s happening to it, it explodes.
01:12 The explosion releases a tremendous amount of energy,..
01:16 ..even more than our Sun can produce in its entire lifetime!
01:21 Whoooaa! Isn’t that crazy?!
01:25 Hmm, let me tell you a secret!
01:28 You could turn into a black hole!
01:32 The computer you’re using, me or anything around you that has matter,..
01:38 ..has a Schwarzschild Radius,..
01:41 ..also called the Gravitational Radius.
01:44 Which is the radius of the tiny sphere,..
01:48 ..into which if a mass of an object is compressed to fit in,..
01:52 ..its escape speed would be equal to the speed of light.
01:56 Which is way too much!
01:58 But chances of you turning into a black hole are rare..
02:02 ..because of the tiny size of your Schwarszchild Radius.
02:07 Stuff that gets too close to a black hole gets sucked in..
02:11 ..because of the super humungous gravitational pull.
02:16 So, nothing can escape a black hole, not even light!
02:21 Hey, have you ever wondered what would happen if two black holes collided?
02:27 Chances are, that they might become one big massive black hole.
02:32 Or probably put up a fight and send one of them hurtling away.
02:38 The bigger the mightier! Hhaha!
02:42 Trivia Time!
02:44 Time runs differently near and inside a black hole..
02:48 ..and this has to do a lot with gravity.
02:53 The nearest black hole to Eath is 1600 light years away!
02:58 Don’t worry friends, that’s too long a time..
03:02 ..but you make sure, you don’t take that long to tune in next time for more fun facts.
03:09 This is me Zooming Out!
