- Hi, I want to ask what happens to someone who passes between two black holes that are orbiting each other so closely that their event horizons are touching. Is it true that such a person would transform into antimatter because he would start to travel backwards in time?
The reason why I think it could happen is that spacetime is being curved really extremely in black holes and when you draw a chart of spacetime near and in black hole , you can see that time axis is being bend towards the center of black hole and that thing is happening from all sides of the black hole, so if you enter black hole from one side , the time axis goes straight to the center of the black hole and theoretically its coming on the other side of the black hole, but in opposite direction.
But of course stuff can't exit the black hole, not even the event horizon, but that is only from the perspective of the viewer outside of black hole and of course all the stuff ends up in the center of black hole because it can't continue its natural trajectory of time axis , because there is center of black hole blocking its path. (same reason why we can't orbit the Earth by simply falling down, there is Earth in a way).
But if there are two orbiting black holes and their event horizons are overlapping or touching, you could travel trough there, but from the point of view of viewer outside, you would just fall in a black hole and at the same time as the antimatter version of you would fall in at the same time as you, but from exactly opposite side of the black holes. But from your point of view you would come on other side (assuming you survive and are not ripped apart by spagetification) and on the other side you would see universe traveling backwards in time, because your time axis would be reversed.
