Now teleportation…

Wormholes!!

Also, time travel forward is only theoretically possibly in the sense that time would pass at a different rate near a black hole. So if we ever develop technology capable of breaking away from the gravity of a black hole we could travel some petty number of years into Earth's future. So even for forward time travel we need to figure out first how to break the laws of physics.

Or approach the speed of light. We can't reach the speed of light ever, of course, but if we traveled at say, even 0.5c the effect would be significant.
