The spaceship “exists” (I don’t really like using exists in this context because it is confusing) in the sense that in the futures where someone figures out how to break the speed of light, I know I can interact with the spaceship. What is the probability that I can break the speed of light in the future?
Then for Many Worlds, what is the probability that I will be able to interact with one of the Other Worlds?
I would not care more about things if I gain information that I can influence them, unless I also gain information that they can influence me. If I gain credence in Many Worlds, then I only care about Other Worlds to the extent that it might be more likely for them to influence my world.
We’re assuming you can’t break the speed of light or interact with the other worlds.
It’s a one-way influence. You can influence the spaceship before it leaves your light cone (you can give them supplies, etc). The MW argument is that you can influence parallel universes before they split off.
