That would mean speed of light is far from being fasting thing in universe.
The crafts they’re describing would only have to come from a mothership, no way they’re capable to travel vase distance.
Don’t believe it.
Now having said that are their intelligent life out there? That could very well be possible. But I think intelligent life came and went since window for it existence is limited. I hope that makes sense.
Makes no sense to even have them out there where our personnel can see them if they are ours. Risks letting everyone know we have the capability for what benefit? Around our best pilots and radars? Stupidest place they could be.
Since we want a minimal power estimate, we took the acceleration as 5370 g and assumed that the UAV had a mass of 1000 kg. The UAV would have then reached a maximum speed of about 46, 000 mph during the descent, or 60 times the speed of sound, at which point the required power peaked at a shocking 1100 GW, which exceeds the total nuclear power production of the United States by more than a factor of ten. For comparison, the largest nuclear power plant in the United States, the Palo Verde Nuclear Generating Station in Arizona, provides about 3.3 GW of power for about four million people [16].
Of course that assumes they haven’t found a way to eliminate their mass.
There have been quite a few ideas put forth about traveling such vast distances. Such theories involve black holes, worm holes and the bending of space to make long distances rather short. And while we don’t know the physics to do such a thing does not mean that it doesn’t exist.
One theory that I find fascinating is the what if these craft are really us from the future. Say a couple of hundred years from now mankind is able to time travel. And we have developed ships capable of what these craft seem to do. Would future us want to do back in time to see how mankind on Earth developed? Hell, it might even be a tourist attraction.
I’m not sure anything is capable surviving a black hole. As for wormholes entry and exit ramp has to be precise. To bend matter/space would require so much energy to be directed that would be impossible. Exploding star perhaps.
As for time travel that is a possibility…which means we haven’t destroyed ourselves. But then what would the chances be they they won’t go back in time to alter history?
