Many scientists believe we are not alone in the universe. It's probable, they say, that life could have arisen on at least some of the billions of planets thought to exist in our galaxy alone -- just as it did here on planet Earth. This basic question about our place in the Universe is one that may be answered by scientific investigations. What are the next steps to finding life elsewhere?

I watched the conference. It's a pity SETI was never mentioned and I don't refer only to SETI@home but to the various institutions doing SETI search.

Searching for life and searching for intelligent life are two different things. I think finding life out there in some form will be relatively easy and accomplished soon. Finding intelligent beings on the other hand will be difficult unless they cooperate and make it easy. It could happen at any time but if we must find them on our own it may take centuries.

I think Bob is right. It is quite likely that we will find evidence of microbial life on other planets in the next few years. But to quote McCoy "It's life Jim, but not as we know it".

That is the fundamental difference. All ET's in Scifi films are bipeds, simply because human actors need to play them. Ok so Jabba the Hut was a one ton puppet operated by three people, but how likely is is we will find human like life out there?

Fred Hoyle imagined a living being made up of gas in "The black cloud", 1958, the best science fiction book aver written.

All these new worlds exactly none are earth like only in size and in the Goldilocks zone. All are too far even to send a robot to. Most would take over a million years to get to. Glise worlds 1,350,000 years one way. The CLOSEST star is 73,000 years one way @ 30,000 mph.We cant even physically see even if they have a atmosphere.All this tells me that to get to another star will require a million years plus journey. Be bad to go all that way and fins out the planets oxygen level is way too high and air pressure is 90 atmospheres of pressure. That cant be measured from 55 light years away. So any of you believe in ET hes traveled a million years to twinkle their lights in our sky and never once communicate.

There are other dimensions though and so forth as Dr. Hawking stated, 11 of them, he had to correct the amount iirc. Humans are made of matter, as animals and all other living beings on our planet. My point is we have yet to broaden our inquiries and 'evolve' in our own rythm, in equillibrium with the Universe, our time will come if we keep it in good hands...

We maybe the first life in the galaxy we may travel into space as family's and many generation late arrive on a planet that can support us but Seti work will still be helpful in many ways

We could go faster in the future. We could accelerate at one G for a few months if we had enough "Fuel"--but we would have to know where we were going to find a hospitable planet. That is the problem.

We might undertake a multi-year trip to another star system; or even a multi generation one in another 1000 years. The challenge will be to find a truly habitable planet close by. If the nearest one is 30,000 light years away then we will never find it

I think, most likely, that the three dimensions we live in are the only ones we will be able to explore and discover alien life in. Most scientists agree that the other eight are so small that they don't occupy space as we know it. In a similar vein parallel universes may be a reality but are most likely inaccessible to us. But that still leaves a lot of space for us to search in.

But we must remember finding extraterrestrial life and travelling to where it is are two widely different things. With the exception of other life in our solar system.

We will never be able to succeed in the second part. Unless we find a way to accelerate the speed of light by a factor of minimum 100 and travel by that speed.

We need to take baby steps before tackling interstellar travel. We need a faster method of exploring even our own solar system, first. Right now and for the foreseeable future all we will be able to do is look outside the solar system. It is said we will discover other life in the universe in the next 20 years. I think that is extremely optimistic.

We could discover Life without going to where it is. Hopefully someone will beam us a strong signal that we will not ignore in the putative next 20 years.

If it occurs , I think that it is likely to be a one-time event and come from many hundreds of light years.

Hawkings mind sees dimensions we do not or you would encounter something every day. That dont happen. Hawking is theroizing these diminsions travel between them I think not. We dont have it a way to manipulate out dimension to visit another and go back and forth but can you return to your time in a diminision. The paradox is that you cant go back in time only ahead. If you could go backwards in time you would alter something change it in a minute way and it cant be corrected.
