1. Is it possible to protect a space ship from enormous gravitational force from a black hole with a repulsive magnetic field?
2. What really happen with a space ship when approaches event horizon.I mean information can pass from this point further why not matter as is our space ship? And where goes the information, in another universe, in another time of our universe or in another space of our Universe?
2. Approaching the event horizon, the gravitational field gets stronger and stronger. Eventually the tidal forces (simple version comes down to the fact that the gravity is stronger when you’re close, and weaker when you’re far. This difference in force is what stretches the Earth and causes the tides we see at the coast) become so extreme that the ship gets pulled apart, along with everything in it. But assuming that we find a way to deal with the tidal forces and prevent this, what happens? Einstein’s theory of General Relativity says that a strong gravitational field affects the passage of time, so time begins to slow down for you (we call this Time Dilation). The rest of the universe seems to speed up, and this effect gets stronger as you get closer to the black hole. Eventually you get to a point where this time dilation becomes infinite and, for all intents and purposes, you stop moving. You, falling in, don’t feel like you’ve stopped, though. Instead, you see the rest of the universe speed up and become infinitely fast. So what this means is that you never make it all the way in. Everything falling into a black hole, from space ships to clouds of gas, even beams of light, get to a point where they just stop moving (from the point of view of somebody outside, looking in). This point, incidentally, is past the event horizon. The event horizon is the point of no return, where even light eventually gets stopped and falls back in, so we can’t ever actually observe time stopping.
What happens past this point? Well… nobody knows. When you try to do the maths to work it out, you start having to divide numbers by zero, or use numbers even bigger than infinity, and these things just don’t exist. Mathematics doesn’t work that way. This is what physicists mean when they say that “The laws of physics break down past this point” – the maths just become gibberish. Some people interpret this as meaning that nothing exists past that point, and that it doesn’t even make sense to ask what happens inside a black hole. Others say that we cannot ever know, because the maths stops working and it’s impossible to get anything past the event horizon because at that point the tidal forces are so extreme that even atoms get torn apart. But one thing is certain: Whatever goes into a black hole stays there. Information going in is destroyed. Matter is destroyed, and compressed to infinite density.
It may turn out, in the future, that some better and more complete laws of physics will be written, which will allow us to pass through a black hole, and show that matter reappears somewhere else, but according to physics as we understand it today that simply isn’t possible. The universe, as we understand it today, is not built in a way that allows this. And if it is possible… well, no physicists could answer, because they can only say for sure what the laws of physics predict.
It’s quite sad really, because it means that all the best parts of science fiction (The faster than light travel, the travelling through wormholes, the vising aliens) are utterly impossible. All we can do is hope that some new Enstein or Newton in the future finds a new physics that shows that we were wrong all along. And, unlike all the guys with their new theories selling books on the internet, that he turns out to be right when other scientists check it out!
