    Nuclear propulsion comes to mind as does project Orion, where we can reach a hefty percentage of the speed of light. Quantum entanglement is basically teleportation on a particle scale, maybe we could utilize this.

    Let's not forget one important problem with fast propulsion or even warp, laws of physics aren't going to look the other way. Accelerating in space still crates g force, and meat (aka the crew) can't withstand prolonged high G acceleration, or short but very high G one. So the vessel would have to accelerate over a long period of time, same goes for deceleration.

    And for the quantum teleportation goes, as far as we are know, we can only send information faster than speed of light, not matter. And the subject is touched on in a books Blindsight and Echopraxia by Peter Watts (highly recommended for any scfi fi fan) with something called telematter.
    Spoiler for telematter:
    In those books we built something called Icarus Array, which is a power plant orbiting sun producing anti matter, which then is cracked into quantum specs and sent at a speed of light to a reactor either on Earth or on a ship where the reactor makes it's own anti matter by imprinting that quantum specification on it's substrate giving the ship basically limitless fuel tank although it cannot send the anti matter itself

    Good point on the g forces I assumed it was somehow accounted for due to it being an actual government project with freemon dyson, I didn't really think about it. I mean they did draw up plans for it.
    Also tachyons could be considered matter I think even though they have negative mass or something

    Tachoyns are hypothetical.
    In a book Odyssey One we have a drive called transition, where the ship is temporarily converted into a cloud of tachyons that jumps instantly to it's destination, the distance is limited by the power output of your reactor.

    Also nuclear propulsion is held back by a ban on nuclear tests.

    What do you think of Peter Watts as a sci-fi author? Do you like his handling of future technology from the characters ' view point? Does he go too far and bog you down with jargon and imaginary inventions and implausible physics?

    Blindsight and Echopraxia are both hard sci fi. Most of the tech he describes in the books is possible / plausible. He tries to reasonably explain how things work instead of pulling a rabbit out of a hat. And both books talk a lot about the nature of intelligence and consciousness which is nicely presented in a not so distant sci fi world. I really liked both.

    Since when can information travel faster than the speed of light?

    good album. I like the books by the same name too.

    Since the discovery of quantum entanglement.

    well as far as I know, entanglement does not strictly mean that information is actually travelling somewhere faster than light... but I know too little about the subject to be honest.

    The tests done so far shows that the information reached the target faster via the entanglement than a laser beam. More tests need to be done to determine usefulness of that as well as the limitations. But at least some information can travel FTL.

    can you show a reference to this? also, you have to move entangled particles apart from each other before doingbanything, which certainly can't be faster than light anyway.

    This one just popped up, seems like they did those tests about limitations while I wasn't looking. It seems only the information about the entangled particles can travel FTL so we won't be sending FTL texts any time soon. But we could check up on something on the other end of the galaxy and see if it's still there.

    As for the second part. In Hyperion AIs developed matter transmitter and gifted them onto humanity. They allow us to teleport over vast distances instantly. But first you need to get the transmitter there. Ironically we also have human invented Hawking drive which allows us FTL travel. However as we move faster in space we move slower in time (relativity) at FTL speed something called time debt develops. Where crew of the ship would spent 6 months of travel in the hyperspace but 11 years (or something like that, don't remember the exact figures) would pass for everyone outside their hyperspace. Also the crew had to be in stasis or it would damage their brains.

    If anyone here is looking for a TV series to watch and likes space, The Expanse is something you should try.
