Black Holes

A black hole is a region of space in which the gravitational field is so powerful that nothing can escape
light can not escape a black hole!
But one can be seen from the matter falling into one

Our universe sprang into existence around 15 billion years ago. prob; from a singularity. Singularities are zones which defy our current understanding of physics. They exist at the core of black holes. The pressure is thought to be so intense that matter is actually squished into infinite density .These zones of infinite density are called "singularities." Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense. Where did it come from? We don't know.

I have one question. How come there were sounds, there is no air in space so it would be impossible for an explosion sound to come from the big bang and dieng stars. It makes no since.

"In space, no one can hear you scream" !!!!....When a star explodes it ejects vasts amounts of gas!!

Air contains roughly (by volume) 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide, and trace amounts of other gases. Sound is a travelling wave which is an oscillation of pressure transmitted through a solid, liquid, or gas! there for like the sound we hear though "Air"....it is also conceivable that sound would travel with the Gas of an exploding star!..A jonnie D Theory!

black holes were rediscovered just 5 minutes ago... light cannot scape black holes because they are in a different time and space dimension. a second in our universe could be trillion of years inside a black hole. and trillion of miles. it's a complete new infinite universe inside a black hole.and yet in our perspective is just a tiny fraction of our universe which happens to be also that we live inside a black hole.

how did the point get there

[serenityintrance]

first of all even a point wasn't exist , all of have been created suddenly by God ;) even a point , search for well

[masegta]

omg.. no, the camera was way back (in space were there is no air, so how cud the noise reach the camera is there wasnt any gases wich can carry noise in space acording to ur trusty jonnieD theory..

[pappucha]

yaa .....i am with you.....were did the point comes frm

[blastrain]

Ohh i get it thanks :)

I feel bad for the poor stars at 2:09 and 2:21, they're being eaten alive :-(
