What do you know about aliens, UFOs and the universe..?

Humanity may never find out.

It is a huge, flying leap of faith from a made-up equation with cherry-picked values suggesting a high probability of space aliens on other planets, to accepting their existence as absolutely certain.

Esoteric faith is for religion, and proves nothing.  Valid facts are for science, and prove everything.

I know there is a lot of talk about them in certain circles and that I find some of it interesting.


I know the universe is beautiful and I know that I am not going to build an HO scale model of it.

Five times ten to the fifteenth power planets.

Actually our galaxy probably just has 300 billon stars -each with five planets.

So that 1.5 trillion planets in our one galaxy.

But only one planet in ten is in the Goldylocks zone, and of those only one in a million gets life, of those only one in thousand has life get beyond the bacteria stage. But once you get to true cells evolution takes off, but maybe only one in hundred planets has dry land (that necessary for a number of reasons), or has livable dry land. Of those maybe one in a hundred gets intelligent land living life.

So thats 1.5 trillion over...one trillion. So there is only one, or maybe two, civilizations in this entire galaxy.

If there is two...then we are one of them. So ... there is another single one- another civilization in the galaxy!. But it could be on the other side of the galaxy fifty thousand light years away. And if so...we will never be able to contact it.

Oh well.

(clicky)an intriguing book in my collection, is "Barlowe's guide to extra-terrestrials" [comparatively rare, long out of print

i expect the above surmisals are but scratching the surface of possible ET lifeforms. i also expect that one day relatively soon i will be privy to much more detailed and truthful information about the reality of it all.

I saw that awesome book in the bookstore of the National Air and Space Museum in Washington DC some many years ago.

All of the creatures are taken from classic sci fi novels (Hugo and Nebula winners). It was an expensive big coffee table book, but a blast to flip through in the store.

I laughed out loud at the article about the "Demu" creatures.

Thank you for reintroducing me to that book!

^^prego from one to another
