What is the most plausible FTL communicator, could we in some way use Tachyons?
I like it especially if it uses the casimir effectmfb said:Probably a matter of taste.
Alcubierre drive? At least it does not directly violate general relativity.
Note that every plausible FTL communication also allows time travel.
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.wolram said:What is the most plausible FTL communicator, could we in some way use Tachyons?
I've never heard of anything like that.Fizica7 said: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?
So, what about FTL communicators which interact with Lorenz ether?mfb said:Probably a matter of taste.

I'm not aware of any plausible theory doing that. There is no point in a Lorenz ether in current theories, so that concept got discarded long ago.snorkack said:So, what about FTL communicators which interact with Lorenz ether?

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.DHF said: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.DHF said:That is extremely interesting. How would FTL communications allow time travel?
A "Plausible FTL communicator" is a theoretical device that would allow for faster-than-light communication. It would work by using advanced technologies such as quantum entanglement or wormholes to transmit information instantaneously over vast distances.
At this time, there is no scientific evidence or technology that would support the existence of a "Plausible FTL communicator." The concept remains purely theoretical and has not been proven to be possible.
If a "Plausible FTL communicator" were to be developed, it would revolutionize communication and allow for near-instantaneous communication between distant locations, making space travel and exploration easier and more efficient. It could also have applications in fields such as telecommunications and military operations.
One of the main drawbacks of a "Plausible FTL communicator" is the lack of scientific evidence and understanding of how such a device would work. It would also likely require immense amounts of energy and resources to develop and maintain. There may also be ethical concerns regarding the use of such technology and potential consequences of disrupting the laws of physics.
It is impossible to predict when or if a "Plausible FTL communicator" will become a reality. It is a highly complex and challenging concept that would require significant advancements in technology and understanding of the laws of physics. It may take decades, if not centuries, of research and development before such a device could be possible.
