This was a screenshot I took months ago while watching a Geology Hub upload on YT. It was a lightbulb moment for my understanding of mass extinction events, (the largest was 250ma). I’ve referenced this multiple times, so thought I might share. Perhaps you find it as interesting as I do.
A safer solution would be to just purposely target your arrival to the other side in empty space. While also travelling in a fully functional spaceship. Just make sure your little ship arrives within a set distance to Earth otherwise you will have to figure out how to travel millions of kilometers to get to where you’re going. If technology gets to the point of developing safe time travelling, I’ll assume that the same level of technology should be able to develop a space ship.
Even easier, send fast-return probes to collect a hard record of locations. Who cares if your prediction models are to chaotic? We’ve already seen the destination!
