Black Holes and how to use them in travel? Or are wormholes even real?
In theory use of Black Holes in travel between stars or even galaxies is a really easy thing. The crew must just fly their craft in the Black Hole, and then it comes out from other Black Hole. But the reality will be a little bit more complicated than theory. If the reality will be so easy as theories are, we would already conquer the entire Galaxy, but there is a small technical problem for making practical solutions for interstellar traveling.
The Black Holes and traveling through spacetime is one of the most fascinating things in the world of physics. The wormhole or Einstein-Rose bridge should connect two Black Holes, but can we benefit that thing ever? And the answer is that we don't know that answer because nobody has ever traveled through the wormhole.
And then somebody says that we would die if we are dropping in the Black Hole, so we must describe the word "die" at this point. When we are talking about death in the case of Black Holes, we should think that death means that the object would fall in the Black Holes, and then the observer would not get any observations from that object, and if that object is some kind of astronaut, we would ever make contact with that creature.
So for the observer, who stands outside the event horizon, the person who drops in that Black Hole will be dead. If we use the technology, what exists, we would die a long time before we can reach the event horizon because the radiation that comes out from the transformation disk will kill us, but the thing is that the idea to use the wormholes in the space and time travel are a very interesting thing.

What if the craft will drop in Black Hole?
What happens when the craft will drop to Black Hole: There are at least five possibilities. But the thing is that the real answer is that we don't know what happens if the spacecraft will impact the Black Hole because no spacecraft ever dropped in any Black Hole. And here I must say, that I will not write about the white holes, or possibilities, that the object will come out from another universe or dimension because it would turn this writing so long.
1) The craft would crush in pieces
2) The radiation would melt the craft
3) If the craft would touch the event horizon, the crew would be stoned at that point. Because the time has been stopped, they will be coming out from Black Hole, when it will be vaporized at the end of the time when there is no material left.
4) The craft will travel through the wormhole, but there is one very interesting point. It can turn the craft antimatter if the spin of the quarks is turning, and the result is a big explosion in that thing.
There is one very interesting point in the wormhole theory, and that thing is the object could be dropped in the wormhole, and travel between the Black Holes forever or until another of them has been turned heavier than other. This hypothesis bases the idea, that wormhole acts as a tunnel through the planet, where the object is moving back and forth.
So if the mass of the black holes that are forming the wormhole is stable the craft cannot come out from it. The reason is that the gravity of the Black Hole turns behind that tunnel, the Black Hole will start to slow the object, and that means it cannot reach the escaping velocity, which allows it to come out from the other singularity.
And at this time we will expect that the information travels in the wormhole two ways. If the information travels only one way, the attempt to use them in the space travel will be like some kind of comedy, where the crew of the craft must try to find the Back Hole what will transport them back to the beginning point.

The reality is a little bit harder to make than theory.
The thing in wormhole theory is that those theories are not ready yet and because there is no (confirmed) information, what comes out from Black Holes, that means that the theory is hard to confirm. When the craft will drop in the Black Hole, it could come out from another Black Hole or in some other Universe. And if we want to read those mission records that require that the craft must find the Black Hole, what connects it to the beginning point of the journey.
The problem is that the Black Holes are quite small if we are thinking about the size or diameter of the event horizon. And if we would even want to fly inside that thing, we must find the Black Hole, what event horizon is big enough. The size of the supermassive Black Hole in the center of the milky way is about the solar system, and the size of stellar Black Holes is smaller. If the craft that dives in the Black Hole is too big, the Black Hole crushes its body.
Even if the craft will fit in the singularity, the speed of it must be near the speed of the light, what denies that the tidal force will not rip the craft in pieces, and the angle must be away from transformation disk because the extreme heat and radiation would melt the craft. So the speed of the craft should be high enough, that it can penetrate through the radiation zones as fast as possible. And then the craft will impact with the event horizon.
That is the point, where even the light cannot turn back, and the information between the observer and crew of the craft will not be possible. If they come out from some other Black Hole, that thing will happen far away from the original Black Hole, so that means that those crewmembers would be dead to us. The reason why they cannot send the communication back to the observer through the wormhole is that they could fly very far away from the point, where they are coming out if they are coming out.
