Here is a list of 3 possible ways that an alien (or us) could travel across space.  At first glance it seems far out (no pun intended) but there might be something to any of these:

1. THE ALCUBIERRE DRIVE

The idea behind the Alcubierre Drive is to basically place a craft within a space that is moving faster than the speed of light. Therefore the craft itself does not have to travel at the speed of light from its own type of propulsion system. It’s easier to understand if you think in terms of a flat escalator in an airport. The escalator moves faster than you are walking! In this case, the space encompassing the ship would be moving faster than the ship could fly, keeping all the matter of the ship intact. Therefore, we can move faster than light in a massless cloud of space-time.

2. Quantum Entanglement: All Points In Space Are Connected

Quantum entanglement suggests that space is just the construct that gives the illusion of seperation. As demonstrated in the vido linked above, if you take two particles and put one of them on the opposite side of the universe, the moment you do something to one of them the same reaction occurs instantaneously in the other one. This suggests that either the pieces of matter are “entangled” or connected, or that information is travelling much faster than the speed of light.

3. Wormholes

Wormholes are passages through space-time that would allow one to create ‘shortcuts’ through space in order to travel long distances. They are predicted by the general Theory of Relativity, and as of now still lie within the realm of theoretical physics. In 1935, Einstein referred to these as “bridges” through space-time, again, connecting two different points in space-time to create a shortcut. It’s also important to mention that the existence of these wormholes has been mathematically predicted, but are still considered theoretical.

A paper that was recently published in the Annals of physics offers mathematical evidence that a massive black hole in our galaxy is actually a wormhole. If this is true, it should be possible for humans to navigate it.

Now if any of these ways worked how would one actually harness them?

We hope you like the enclosed vidoes!
