Thor: The Dark World (2013)
Thor must battle Dark Elves who control the Aether — a cosmic weapon capable of transcending different realms and infecting them with darkness.
What it says about time travel
More a function of teleportation, time travel acts as a gateway to converging realms through which people (Gods and mortals) and objects (Thor’s pecs) can leap.
Real life time travel theory in play: Wormholes
Based mostly in Einstein’s theories of relativity, creating a wormhole would allow the travel between specific points in space-time. In order to do this, you’d have to travel faster than the speed of light (186,282 miles per second) in a vacuum, which scientists deduce would be impossible for anything larger than a particle. [Insert joke about your time-traveling dick here.]
