I voted no, but I hope I'm wrong, but only if they're non-hostile and don't try to destroy is as a pre-emptive strike; presumably if they find us they've a technology way in advance of our own...and could see how utterly stupid and self-destructive we are as a species, and of the others on our planet. Flora and Fauna alike.
 
I look at it this way... If the universe truly is infinite, then there must be infinite variations of stars, planets, atmospheres, temperatures; so logically there must be other sentient life out there.

Our current model of the Universe is that it is not infinite. The Big Bang theory predicts accelerating inflation from 13.8 billion years ago. However, there is the multiverse theory which in practice could be infinite.
 
There has to be a planet somewhere watching this one thinking, what a bunch of stupid people, blowing each other up, and all the other crap, but they have come up with a cloak so we can't see them ;)

Conversely though we're fortunate enough to live in a time where we live on Earth and can go see wonders of nature, Space travel would probably be incredibly boring for the most part. Even travelling at close to Light speed you'd be looking at spending years on a Spacecraft to travel between Stars. In the future entire generations might be born, live and die aboard generation ships.

It's more the travelling to distant worlds I was thinking of, rather than the spending years travelling the "lanes"!

Any species that has survived and developed to being highly intelligent and space faring will most likely have a similar history to our own, though you would hope maybe they didn't have to go through the whole religion thing. In all animal models we know they compete for resources and mates, it's not unique to humans and other species probably have violent pasts, or may very well be violent themselves
 
If the probability becomes so vanishingly small so as to make verification impossible in the lifetime of our civilisation, the problem becomes empirically undecidable, and we might as well be alone. Indeed if civilisations of intelligent beings and lower forms of life keep decaying at staggered and different rates, never coming into contact, direct or indirect (including say fossils and artefacts), before extinction -- the practical effect is number 2. Drake's equation needs a lot of data to become useful; time will tell if it is. And this is before you consider multiple universes. That's to say, infinities are a PITA for any concrete, physical argument, one way or the other.

The fascinating bit's that the harder sciences err on the side of life out there however cautious, whilst the softer sciences, which know a thing or two about life, err on the side of pessimism however well concealed. Fun stuff. :)

Its wasnt a big bang. It was a big expansion, quite a difference.

You know that everyone refers to it as 'The Big Bang' Right? I pay you the compliment of knowing that. I did also mention inflation in my post.

I was simply rattling a response out as I'm quite busy here. ;)
 
I'm sure there is life.

Whether it is 'intelligent' or not is another matter....it's by no means inevitable that life ends up with our level of intelligence. Intelligent life is a mere blip, bacteria and the likes are the real life successes.

Go extremophiles!
 
When they say Proxima Centauri b is in the Goldilocks zone, is that using the same distance as we are to our sun or altered in accordance with the size of Proxima Centauri which is much smaller than Sol?

This image shows what's going on. The reason that Proximal b is closer to the star is because it's star is a Red Dwarf and burns much more cooler than our Sun.

Interesting. So would you be able to look at a cooler red dwarf with the naked eye? Does it appear like the sun at sunset?
