Do you think the event horizon of a black hole is real or do you think it is a mistake in the math or theory?

Question

Tell me why you think the way you do.

I there has to be something to General Relativity, I asking about only the reality of the event horizon.

Answer 1

Oh yeah, there are black holes all right.

And the fact that they exist is going to bring down all current gravity theories.

In science today, they have a problem. The actual experiments are driving them in two different directions.

One, the theory for everything small, - QUANTUM MECHANICS works so well it can't be wrong.

BUT, when you look at large things governed by gravity, they get a different set of rules.

If it weren't for the reality of black holes, many scientists would declare that there was no unification theory. But they do exist, and there is a unification theory.

Consider this:

just inside the event horizon of a black hole, a lot of things will be happening to release energy, fission, fusion just to say the least. Some of this energy will try to go "up" to escape the event horizon, but it can't.

THERFOR: if you were inside the event horizon looking up, the "SKY" to you, would be the most brillant mirror in the universe, because every wave of light would be "reflecting" back at you!

Imagine that!

Answer 2

According to GR something so massive compressed in such a little space creates an amazing gravity. The event horizon was created from this principle. The event horizon is just a name we give to "the place where everything falls in including light". A proof of the event horizon would perhaps be the gamma-ray bursts coming from the black hole. When particles are being attracted by the black hole's gravity, they will emit huge amounts of energy (gamma rays). After a certain time, we can observe dormant black holes where there is no activity.

Answer 3

The event horizon is a more modern term for the Schwartzchild radius. Schwarzchild solved Einstein's equations of General Relativity for a point mass and found the distance from he point where light cannot escape the gravitational field. At the time, it was thought to be a mathematical curiousity since no one thought that a mass could be smaller than its Schwarzchild radius. However, highly condensed states of matter have been found to exist. Any situation where a mass is totally inside its Schwarzchild radius is a black hole and the Schwarzchild radius becomes the event horizon. All predicted by the equations of General Relativity.

Answer 4

The existence of blackholes has been observationally verified. And because blackholes and their event horizons were originally predicted by General Relativity, we can pretty confidently say that if we can verify the existence of blackholes, then their corresponding event horizons must also exist.

Actually, every blackhole has an event horizon by definition. The event horizon is just the imaginary boundary that delineates where the point of no return is, i.e. where gravity is so strong that light can not escape. So no, there is no mistake in the math or the theory.

Answer 5

You can observe the effects of black holes. Ever hear of Sirius X-1? It can't be a mistake.
