black holes

[Wildcat1]

shows about deep space never fail to blow my mind.

was watching one about black holes last night, and apparently the reason they are black is because they are so massive, light does not travel fast enough to escape it. in fact, if you were to get close enough to one, you would not be able to send transmissions on what it is like, because radio waves, which travel at the speed of light, would not be able to make it back to where you're trying to transmit to. as you get pulled in by the immense gravity, since your feet are closer to the black hole than your head, they get pulled in faster, and you get stretched like a peice of taffy, until you are simply squeezed to death. the hypernova explosion that is believed to create black holes is the equivalent to a 100 million-billion megaton nuclear blast, and you can see these explosions from literally across the universe.

i don't know, i thought i would share this with you all, because this stuff never ceases to amaze me.

It's all theory I believe.

yes because we simply can't see one. the only way to find out is to go to one, and the clossest known black hole is at the center of the galaxy.

it would take us nearly 1000 years to get there, and that's at the speed of light

If you placed a very large mirror one light year away in space, and then pointed a very large telescope on earth at it, capable of seeing the reflection of earth and telescope in great detail, and waited exactly two years before looking through the telescope, what would you see?

You lost me right around the part you mentioned a mirror...

And yet, they claim that Gama ray bursts come out of them, in the same show.

 They believe that at the center of every galaxy is a blackhole. My theory is that every blackhole is like beads of water on a waxed car hood. Over the emmense scale of time, the larger beads (blackholes) suck up the smaller ones until there is just one huge blackhole containing everything, all gas, matter, etc in the universe. In a fraction of a second that blackhole explodes in a BIG BANG and the cycle starts all over again.

Interesting theory, I like it.

My theory is our entire galaxy, everything we know of and beyond, is
just another little atom that makes up another larger galaxy, that makes
up another etc.
The 'Big Bang' is just somebody finding out about nuclear physics

*Edit

Before anyone gets critical here, no, I don't actually believe in my
theory, but it's something to tease the mind with

I've watched the same shows on TV.  I like the idea that when a black hole is formed, and new universe is created from the stuff that's in the singularity at the center.  Perhaps then an expanding universe is one contained in a black hole eating up more and more stuff in its own universe.

Earth at the time you pointed the telescope at the mirror.

[RTHolmes]

the sun rising every morning because the earth orbits the sun is also just a theory


black holes, relativity, quantum fields. physics rules

Until of coarse we change them again

Black holes are not eternal... and you guys should know better than starting to rethink the bigbang theory on this forum.

Yep!
Also, this could really revolutionize crime-solving!

Other stuff that is difficult to comprehend is dark matter and dark energy.

Mind = Blown * (speed of light) squared.

I have vague recollections of smoky dorm room discussions of how light has characteristics of mass and, by definition, travels at relativistic speeds. So, does it have infinite mass? Does time stand still? Whoa.
