Are we really alone?

Gee bikers are a deep thinking lot arent they!

As someone said, there are a huge number of stars out there. Chance are there's a huge number just like our Sol, hey to be quite honest, a sun doesn't need to be exactly like our Sol for it to support life. I think many different types and sizes have a "sweet spot" or radius range in which a planet can support life if it is within these bounds.

Also noted that someone mentioned that there are also way more stars than we can see. We can only see stuff that is less than 14.9 billion light years away (also note that if we are looking at stuff 14.9 billion light years away, we will be looking at said thing as it was 14.9 billion years ago). And even within that distance many are hidden behind other stars (which could help for long range viewing with scientists working on gravity lenses), and also many that are just plain too dim for us too see with current technology.

Who knows how far outside our viewable space stars exist? I'd say there's a good chance there's many (I have no idea how many) planets containing intelligent life. But I have no idea whether or not even the greatest intellect could ever travel to different worlds containing civilisations. As things stand the only KNOWN option would be wormhole travel, and I have no idea how that works, and until I understand it and see evidence I'll have trouble believing wormhole theory is relevant to our reality. I might just not be smart enough.

I was in your spell right up to that bit, then you really lost me!

Most definately is life of some sort, but to what level who knows. Us feeble humans try put numbers on things that we do not understand, rather laughable really. WE DON'T KNOW SHIT. hahahaah stupid scientists.

Mathematical constants that are not constant. sigh.. we are just glorified monkeys.. no wonder they don't come visiting us eh

The chances are very good that there are many other forms of life in the Universe. There are a vast number of star systems and 13 billion years for other life to develop. Incidentally our own solar system, at only 4.5 billion years old, might be on it's third incarnation as a star system.

But have we been visited? Much as it would be flattering to think so, recorded human history (about 5000 years) is 0.001etc% of the life of the Universe. What are the odds of aliens - who could have evolved at any time, just turning up at the precise moment we learn to write stuff down? Not good, in fact infintessimally small.

Bummer.

I'm no physicist but there is no "outside". Just the Universe which is constantly expanding. In fact the expansion is accelerating - or at least what we can see of it.

Try and imagine the Universe as the surface of a globe like Earth. We can't see over the curve of the horizon, so we can't see the other side, anymore than we can see England. And if you set off to the end of the Universe, you would arrive at..........Earth. Space is curved.

The globe model also helps to imagine how a wormhole would work. Instead of taking a curved path, you'd cut through a tunnel to England. Much quicker.

For all intents and purposes we're alone. We can't communicate effectively with a spider, let alone identify "life" of an extra-terrestrial nature. We haven't even defined the parameters of concious, sentient life on this one little rock yet.

How would you know that you'd met ET? How would ET know that he'd met ET? What would be the common framework for communication, the ET Rosetta Stone that allows us to connect intellectually? It's arrogant to assume that life doesn't exist elsewhere, but it's just as arrogant to assume that that life would identify Earth as containing life.

I seen some UFO's they werent planes, they werent anything from this planet, about four weeks ago weird arse lights in the sky was watching them for about half an hour while driving home late at night, they were racing across the sky then they where going around in circles. I got home and took Mrs Evil out for a ridse to show her (of course they had gone) then the next morning we had a visitor and I told them the story and they said one of their freinds saw the same lights in the sky....freaky!!!

who know could have been a bunch of stuff, end of the day I absolutely believe there are other life forms, not neccersarily more advanced but why wouldnt there be? I would like to know what sought of bikes they ride, probably Ducatis? maybe thats why they come? maybe they come for Ducati's

If any one want an easy to understand book on the Big Bang theory read Simon Singh's book. Just finished this a few months back.
http://www.simonsingh.net/Big_Bang.html Now I'm an expert. You will be too

There's a realy interesting chapter on the cosmic microwave background and how it was discovered and proved. For all intents and purposes this is the limit of our observable universe. The images that are recorded of the micro wave background are as they were about 14 billion light years ago. So it is anyones guess what has happened outside of our observation in that time span.

PS the Big Bang was a derogitory term phased byFred Hoyle who believed in the Steady State Theory.
