    A time machine is a teleportation machine. If we can imagine a time machine existing, a teleportation machine isn’t really far fetched.

      I cannot wait for time travel to exist so all the pedants online can be like “um actually, it’s a space-time machine”

      Edit: because I am also pedantic like this.

      A time machine is a faster than light drive.

      Well, the other way 'round, really, but same difference.

      And to come back you need a slower than (but very close to) light drive.

      well, if you rewind time and stay in the box, the box would probably stay on earth, but I have no idea how time travel would work.
