That's true. I've seen no evidence for FTL travel, except "circumstantial" - if we interpret UFOs to mean they are coming here, FTL must be possible. But even then there's a get-out clause, they could be coming from Venus / Saturn / some moon in our solar system.
Although "Quantum Teleportation" could that theoretically be used to "teleport" a spacecraft FTL?
- krapp 8y ago>Although "Quantum Teleportation" could that theoretically be used to "teleport" a spacecraft FTL? Everything I've ever read about quantum teleportation says no [0..2]. Even if state changes are instantaneous, the transmission of information itself is still limited to the speed of light (and a ship counts as "information" in this case), and the process of quantum teleportation would require some classical communication channel to transmit state. All that notwithstanding the amount of energy you would need to "entangle" an entire ship in the first place.
