Well, with multiverse theory it is possible we might get occasional visitors from the multiverse. However, if this universe it is unlikely we will even encounter aliens from another world, unless either we or them master the ability to travel distances by "folding" space. On our side, that is unlikely to happen in our lifetimes.

About the time I think I'm alone, I simply try to talk along Seventh and Broadway... Feeling's gone. I am definitely not alone.

No doubt about it. Yes there is life out there, the possibility is extremely high.

I'm sure you must know of the Drake Equation. I believe it is likely there is life elsewhere, maybe even intelligent life. But might we stay alone through the time we destroy ourselves (which I think we're in significant danger of doing)? Yes. The distances, as you say, are so incredibly vast.

no, i don't think so as with infinite space there are infinite possibilities

Semantics on exact meaning of "alone" may be confusing. But since we are talking about "in the universe" we mean the whole universe space where I could say we're not alone if a living being is found even far away in the universe.

With more stars in the Universe than grains of sand on all the beaches in the world, I would bet on life. We are expanding our understanding of our galaxy and advancing our technology levels at an astounding rate. Its only a matter of time until we get that signal or contact from other sentinel beings.

I hope there is other life on other planets.

I think we will find life on Europa. And at some point, humans MUST strike out to colonize planets or become extinct.

Neil DeGrasse Tyson had the BEST response. He stated there is 1% of difference between our DNA and ape DNA. If you extrapolate that out to alien life, ie. 1% of difference between their DNA and our DNA . . . .Why would they EVEN want to try to talk to us? We'd be like very low life forms to them. He could be right.

?

I will let you know when I find the light switch to the universe.

More scientific study needed.

As far as we know, we are the only planet with our form of life. There may be other life forms on other as yet unreachable planets.

Interesting perspective. Thanks.
