Me...and Enrico Fermi. [:)]
Seriously, it's been ginned up to look like it's a real scientific equation, when its result is no better than a guess.
Infinity = proof of advanced alien life flying around the multiverse.
The Drake equation pertains to our galaxy only. Whether there are aliens elsewhere is not very relevant, since the distances are so vast that we'll never even be able to establish radio contact, much less have a face-to-face.
We could if we intermarry.
Ok, so you're a star-traveling space-farer who's just arrived at a habitable Earth-like planet covered in pond scum. Do you:
a.) Intermarry with the pond scum? or,
b.) Break out the pond scum remover?
You "know"? LMAOROFL!
Yes, we know that every star in the sky hasn't yet been colonized by radio-com'ing beings - because SETI would have found it straight off. Since they haven't, it's safe to assume that it hasn't happened yet. And it's about to happen - by us! While it will take millions of years, that's a mere tick of the clock cosmologically. Since it happens so rapidly - in cosmological terms - the fact that it hasn't yet happened over the galaxy's billions of years means that it's very unlikely there ever were any other space-faring civs in the galaxy before us.
I suspect that planets that are billions of years older & have achieved warp travel consider us to be mere primitives. Silly to think that we're alone in the multiverse.
I never said anything about the "multiverse" - or other galaxies - just ours. Warp travel is science fiction. To travel faster than the speed of light you have to get around Mr. Einstein. But even if you somehow can do that, you then run into Mr. Fermi again. You're faced with that same paradox: If there really are intergalactic space farers out there that can zip around the Universe at will, where have they been? By odds, they would be just as likely to arrive when we were pond scum as now - and then they break out the pond scum remover. Our very existence proves it can't be done. The only way we're allowed to evolve from pond scum to sentient beings is if we never have any visits by voracious space colonists.
