Knowing there is an intersecting universe with our own universe would be a frightening prospect. All that spinning and exploding. Like two saw blades on a tilt. Sparks everywhere, amirite?

I wanna think that the gravity pushes and pulls the planets and stars away from each other , it probably isn't total destruction. Plus time would be on your side as you wouldn't be able to be born and live in the extreme conditions leading up to collisions that takes hundreds of years , the people to witness something like that would probably be cooked to death by rising temperatures. to witness something like that realistically from the inside we would need an old camera that has been running for about a million years. then we would have to collect the film and speed it up so that the million years can be seen on our time frame. I think you may be disappointed to witness it from the inside it would happen so slow
