Are white holes exist?

[Bla]

You mean if energy cannot escape, neither can matter.

About the energy inside a black hole:
If matter turns into energy inside a black hole, and if a photon does not have a mass, the black hole will in the end lose so much mass that the energy and matter will be able to escape.
However, if the black hole does not change the form of the matter into energy, it may be trapped inside it forever.

But, if the matter is very hot, I assume some of it will turn into photons, so, that must mean black holes will lose their matter in the end.

Correct me if I'm wrong.

[FGFG]

The particles, however, remain into the black hole.

(I'm not sure of this, I should have read it somewhere)
If mass creates gravity (F = G*(m*M)/d^2) and E = mc^2 then Energy creates gravity (again i'm not sure at all).

[Bla]

The strange thing is that photons don't have masses.
Or, earlier I read that it was possible that they could have masses below a very very low value.

But now Wikipedia says no mass. So if that's correct, energy doesn't make gravity.

[FGFG]

I don't think that the heath makes matter become energy, but instead, it could transform itself in matter.

EDIT: In the particle accelerators here on the Earth, we create matter by making 2 particles crash at relativistic speeds. This make the enormous amount of energy involved transformed into matter (so we obtain the various subatomic particles)

Again, same thing.

If energy cannot escape, neither can matter.
That means that light, or heat can't escape, yes, so since matter goes slower, it can't.

So, If matter can escape, energy can!
That means that if slower matter can escape, the faster light and heat, obviously can too!

[FGFG]

And what's the why for this enormous post? I thought that it was clear...

[Bla]

But in my case, where I corrected it, there was a diffrence.

If energy cannot escape, neither can matter. True.
If matter cannot escape, neither can energy. False.
Since energy is faster.
...In a vacuum at least.

[atomic7732]

If matter cannot escape, neither can energy. False.
Since energy is faster.

Im saying can  

And what's the why for this enormous post?

Umm... to make it clear.

I thought that it was clear...

I didn't think it was.

[FGFG]

It is not related with what we are sayind now but...

The more an object goes fast the more it will appear massive for an external observer.
A part from the space-time dilatation, a normal object, to reach the speed of light, should have infinite mass.
So speed creates gravity...

[Andreas]

white holes donĀ“t exist.

Think logical. What would happen if such an object spills out matter in large amount?
Right! gravity wins over matter and a black hole would form.

[Bla]

But if the matter is spewn out faster than the escape velocity...

[Andreas]

who cares? Its still a gigantic ammount of matter that would constantly collapse into black hole.

[Bla]

Don't worry, I don't believe in white holes either.

[FGFG]

If white holes exist they are joint to a black hole, so the first black hole should not increase its mass if it is ejected in another point of the space-time. Till now we didn't see any black hole with constant/decreasing mass.

[atomic7732]

Whitw holes. Meh... Who cares.  lol

[atommo999]

i get confused with white holes... i mean, it seems to just be one end of a wormhole

[monmarfori]

You know white holes are repelling objects. for example. a star passing near a white hole. then it will throw out (or repel).

[Naru523]

Yes I know, like in that dust game.

[monmarfori]

But. it is only in earth editor.

[rottweiler07]

I believe that Einstein's theory of Realativity stated that Black, white and worm holes could exist. Correct me if I'm wrong.

[Bla]

I believe that Einstein's theory of Realativity stated that Black, white and worm holes could exist. Correct me if I'm wrong.

Black is right, wormholes is also right, but I don't think it said anything about white holes.
Also, remember wormholes don't have to connect black holes or stuff like that in games. Wormholes probably exist on a very small level, much smaller than quarks.

I just think white holes is a strange idea that tries to make places in the universe magically connected, so we can use them to travel. I don't believe in it, I more think it's wishful thinking.

That isn't actually creating matter, just changing it. And maybe white holes and black holes are similar to magnets. (joking) But maybe they actually are...

Look it up on wikipedia. Interesting stuff.  http://en.wikipedia.org/wiki/White_hole

[Naru523]

Here's something interesting... (Note: you have to go to the source because the picture is too small )
