why do you need to study blackhole?

Question

in terms of physics

Answer 1

Because understanding the terms of black holes, allows you to understand soo much more about physics. And besides, I just research because I have too much time on my hands...

Answer 2

There are two primary reasons for studying black holes.

The first reason is that black holes are simple. I know what your thinking. Using simple and black holes in the same sentence is something that should never be done. However the fact of that matter is that the general relativity solutions for black holes are comparatively simple, they're completely spherical point masses. The first exact solution to Einsteins field equation was the scwarzschild metric, for black holes. Before that Einstein doubted that any exact solutions would ever be found. Now there are 3 more main solutions for black holes, the Kerr solution, the Newmann solution, and the Kerr-Newmann solution. These equations can then be adjusted or approximated for similar non-black hole scenarios.

The second big reason is quantum gravity, so called "theories of everything," like string theory. Black holes are one of the few places where we can observe quantum effects in an object of non negligible mass. This makes them a perfect testing ground for quantum gravity predictions, as well as a way to try to derive relationships. Hawking, for example, showed that a black hole emitted radiation through quantum fluctuations around the horizon, going on to show that a black hole has an entropy and a temperature.

The again you may ask why we care about GR and quantum gravity. Well GR is used in global positioning satellites to correct for the difference in the passage of time at different gravitational potentials. It also allows us to derive the equations explaining the dynamics of the universe from a fraction of a second after the big bang on. As far as quantum gravity goes, it will allow us to explain what happened in that first half of a second, also it gives us an excuse to play with big expensive toys like particle accelerators.

Answer 3

I don't NEED to study a black hole.

Nobody NEEDS to study a black hole.

But a black whole is a wierd place (in terms of physics) where wierd things go on and that is where you can learn new things (in terms of physics).

Why did Charles Darwin want to go to the Galapagos Islands and why did he learn so much on that trip. Because those Islands are wierd (in terms of Biology).

Stay at home studying the things that have been studied and you might learn a little. Go find something wierd, new, hard to get to, (like a black hole) and you just might come up with a new "Origin of Species" (in terms of physics).

Answer 4

you need to go to space school. and fine out more about the black hole in space........take you time. and read more about it. and you will see more of the black hole. a black hole in space is just a open space with out the star. and ther for the blackhole will stay like it is. it's just a big black dark smoke in space. ps. jay rock (c) 2006.

Answer 5

Some scientist said black hole is the other side of our time(VORTEX), they said it is possible to travel in time using a black hole.

Answer 6

It can be a great source of energy if we know how to harnass it.

Answer 7

Perhaps because they are so incredibly fascinating!
