What can you say about the expansion of the universe? After a certain point, it starts to expand at superluminal speed. And this, by the way, is within the framework of General Relativity.
I didn't quite understand. I think what is meant is that in our frame of reference, two distant galaxies are moving away from each other at superluminal speed. But it is not necessarily the case in their frame of reference. WhiteLizard
So, the space in front of the starship is shrinking, and the space behind it is expanding? Then it turns out that the space itself is moving, and not the starship) such a system is in Star Trek.
It seems like it. But it's better to watch the show, it's on Discovery Science.
