What is the most plausible FTL communicator, could we in some way use Tachyons?
Tachyons are only hypothetical mathematical things that can only travel faster than light, I'm pretty sure nobody thinks they actually exist any more then, say, a negative number of apples can physically exist.What is the most plausible FTL communicator, could we in some way use Tachyons?
I've never heard of anything like that.Now this info I remember is like 20 years old... so.... Wasn't there a type of seastar that would show spooky action at a distance like if researchers would move the leg of one seastar then the other seastar would also move the same leg kms away?
There are a few SF-franchises that use wormholes in an interesting and (whisper it!) realistic way, insofar as them not being considered straight up impossible. To avoid issues of time travel the wormholes have to be physically transported to the points needing to be linked and any attempt to make a roman ring causes the wormholes to instantly collapse. IIRC it was physicist Matt Visser who proposed the latter might be a real consequence of stable wormholes.Could you open up a stable wormhole? It doesn't have to be big, just big enough to pass regular slower than light communication through.
I don't see it either. I'm picturing a simple set-up in local space, suppose a satellite at the Sun opens a wormhole next to the Earth to send a message that a flare is headed towards Earth. It saves the ~8 minute "c" delay for the message to travel, but I don't see any reason to conclude causality would be violated.How would FTL communications allow time travel?
Everything that is FTL in one reference frame is backwards in time in a different reference frame. That is an unavoidable consequence of relativity.That is extremely interesting. How would FTL communications allow time travel?
