Also a statistical fact - each star has at least one planet. So in out galaxy that would be about 300,000,000 planets at the minium. As for the distance thing - just imagine you had one of the very rare copies of “Dynamical theory of the electromagnetic field” and were well versed in theoretical physics.
Would you conclude as Oliver Heaviside did that James Clerk Maxwell’s 200 quaternions were garbage and only four really could be converted into vector equations?
Or would you actually study them as they are and conclude as Nicola Tesla and Albert Einstein did that there was a lot more there? That there is no such thing as distance, since it is possible to step from any one point in the universe to any other point instantaneously?
If you were an Alien from some other star and not bound by our Earth cultural norms and consensus thinking, might you just make something with that knowledge so you could travel anywhere in the Universe?
But then you aren’t an Alien, and so would you fall back and support Heaviside’s trashing of 196 of the quaternions and reworking four of the quaternions into everything we now know about the entire electromagnetic spectrum?

And, if we have -- and can use -- what he mentioned -- I hope we can find a few worthy brains to send along with it.
My point was -- IF "they" come here right now -- "vermin extinction" would be the likely result...
