# A black hole

What if a star is much get close to a black hole ?. For more or less what you see in the video.

In principle, the outer layers of the star, plasma and gas, would be swallowed up in the first place. The outermost layer, the photosphere, would be the first to be torn and, close to the black hole rotate, accelerate speed to become hot ionized plasma (which would make more than to shine in origin).

When heated, the neutrinos would escape, while still engulfing the star shine by the Cherenkov effect can be observed in nuclear reactors. This effect is that particles passing through a medium faster than light (to escape the neutrinos of a hot medium, let the plasma of the star to be swallowed, photons themselves) produces a shock wave of a color blue (like in the movies). Remember that the speed of light, depends on the medium, although it has a maximum speed can be slightly lower.

Finally, the beams emerging from the center of the black hole are but waves of X-rays due to the angular momentum of the material that is falling in.

It’s very simple. The laws of physics are the same are where they are and there is a very important, conservation of angular momentum. Angular momentum is the distance to the point, by the mass and velocity. When approaching the object to the center of the black hole and taken to conserve angular momentum, with decreasing distance and mass, be constant, all that can increase the speed.

Obviously, the universe has a limit, the speed of light. After approaching the event horizon, the speed of the object can be virtually the speed of light. Then, if you need to conserve angular momentum and the speed is already high, means that the mass must be reduced because that’s all you can touch. If the mass is reduced, means that energy spitting if it spits energy X-rays (c’mon, radiation).

Think that radiation in the form of X-rays is detected, knowing that nothing escapes from a black hole Hawking radiation safe (and has to do with the mass of the black hole, its center and its event horizon, one of the only ways a black hole can “evaporate”) is emitted by the mass ends up in the black hole before reaching the point of no return, where there is so grave that everything (to X-rays) falls within.
Remember, too, the black hole mass is winning as he absorbs must also change its angular momentum being the rotation speed close to the speed of light (which is a lot, by the way).

Consider also that, as I have shown at other times, the clouds of star material surrounding the black hole are so dense that absorb most of the X-rays emitted by matter itself, hence only look “out” the black hole at the edges no matter where we go, in the case of video, up and down.
