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.
