Yes I'd completely agree and after looking at images like the Hubble Deep Field the true mind numbing scale is insane. The extent of human radio broadcasts in our galaxy isn't that impressive either.

Updated Drake Equation Suggests We Might Be - Maxmars - 06-07-2024 If our "presence" within the galaxy is that limited (a mere 200 light-year sphere) we can probably be certain that no other civilization with "similar technology" could ever find us, other than good fortune. But that's just for any other theoretical civilization 'like us,' within that small portion of the galaxy. But then, higher technologies will appear as magic to us... maybe someday we'll know more. Perhaps distance is just 'an illusion' to higher technologies. RE: Are We Alone In The Galaxy?

Same here. The ingredients for life to exist are the abundant in the Universe and life can probably manifest in very different ways, it doesn't need to be carbon based. But first of all anyone who looks at this issue needs to appreciate the numbers involved. The Universe contains (a recent estimate) around 2,000 billion galaxies and each one on average contains 100 billion stars and at least as many planets. Very unlikely we are alone. On the other hand we haven't even explored our solar system. Let's see what's underneath the icy surface or Europa and Enceladus first. I think there is a good chance we answer the question if life exists on other planets. RE: Are We Alone In The Galaxy?

I agree but would go a step further. I suspect many civilizations would be subterranean. So you could potentially go to any number of planets and find life. Our mistake is combing the surface (though I do suspect we’ve found things that have not been shared with the public). |
