How do aliens travel through space?

Answer 1

In their UFO's.

============================

If you want to make up aliens, then you can go ahead and make up any mode

of transportation you like to go along with them. You're writing the story.

This is not to say that aliens definitely do not exist. No statement can be made

either way, pro or con, because so far, no credible evidence whatsoever of their

existence or positive non-existence has been documented.

==============================

Aliens are not even confirmed to exist, but the general eyewitness reports say they mostly travel in round spaceships, which have been named UFO's, which simply stands for Unidentified Flying Object. How these work (hypothetically saying they do exist) has never been agreed upon, and nearly all of their features are disputed depending on the witness and area. The only other feature which is agreed upon by most cases is they have lights on them,.

They are also commonly reported to be triangular, but government officials say these can easily be B-2 Bombers or "Stealth" bombers, which are shaped very oddly so they can deflect radar waves astray (therefore making them invisible to radar). The bombers are shaped in a triangular-like fashion and are full black.

Answer 2

There is no scientific evidence of aliens traveling through space. However, according to theoretical physics, aliens may potentially use advanced propulsion systems or technologies we have not yet discovered to travel vast distances in space.
