UFO Propulsion! Have we detected evidence of huge alien ships riding radio beams?

This is the first in a series of videos about how alien civilizations might travel to our Solar System at relativistic speeds. This particular propulsion system uses a powerful radio beam to push massive ships to 50% of the speed of light. And, amazingly, we may have observed advanced civilizations doing this already! <br>#space #alien #nasa <br> <br>Please support my North America Tour!
