And by aliens I mean, outer space creatures and UFO. For whatever reason all UFO sighting footage looks either fake or like recorded with a Casio keyboard. And I find hard to believe we don’t have any decent footage of them with all the surveillance and technology we have now.
Edit: 🍿
Saying FTL is possible is equivalent to saying effects can proceed cause, the two statements saying the same thing from different frames of reference. You can demonstrate this with the Taychon pistol paradox (you could use a gun that fired FTL bullets to shoot yourself in the past).
Wormholes could avoid this but only if the mouths of the wormholes moved away from each other at slower than the speed of light.
Ok, I deserve this since I said “Go.”
I’ll spin the wheel again. How about a generation ship they used to park on the far side of the moon. Actually a fleet of them. Occasionally, they send a lander down to pick up a farmer they can anally probe: the Hallmark of advanced civilizations. How about them apples?
