Rules:
- History of the world before your birth remains the same; only events happing after your birth can be changed.
- The other version of you must still be alive, you cannot go to a world that you are dead in. (This essentially forces you to murder/abduct your alt-self, so travelling has a ethical cost to it 😉)
- There may be other multiverse travellers out there
(Btw, is it ethical to murder an alternate version of your self? Is that even murder or just self-harm technically?)
Can I go to a universe whose me is not there (in another universe)? Can I go to a universe that has another me but the original me from that universe is dead?
Alternatively can we all (along a finite curve) go to existence record 3.50 where we over throw all the nations governments by our collective numbers redirect the governments to both properly steward the environment, and create social safety nets. Once we do one, we will snowball and tackle another universe slowly adding tasks and learning as we go and work on creating a wormhole that replicates our natural ability so that we can visit the ones where we are dead.
