  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’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! 01:31 Yup! 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!   [/vc_column_text][vc_separator][vc_column_text]
