For decades scientists have been scanning the universe in search of alien life, but what if we made contact and the aliens turned out to be hostile?

shining a laser

Eliminate that dip in brightness. You do this by shining a laser in the direction of alien observers. All we need is 30 megawatts of power, which equals about 10 wind turbines. This could be a useful way to hide from hostile aliens. but it could also be a way for aliens to hide from us.

David Kipping from Columbia University said, "It's possible what we see as we scan the universe for other habitable planets has been engineered to disguise ot highlight the existence of other civilizations."
