Well, ..., Most likely there are other worlds out there with life on them (though life doesn't mimic Hollywood ... Hollywood mimic life and then grossly overstates it). It's just that currently we don't have any observational data to support the existence of life anywhere else but here on earth.
From a societal point of view, though, unless we grow-up as a species, the discovery of life elsewhere would have a devastating affect on our culture. We have a tendency to look at ourselves a superior or inferior to a race or group of people. One only has to look at the atrocities committed by the Nazi's to understand how horrible we can treat people who we rationalize as not-human. Hawking (see below) thinks an advanced ET society may treat us the same way. I certainly think that if we were to find a less advanced culture that we would repeat the failures of the past. So for now, until we grow up, we don't deserve to find life living elsewhere in the universe.Isn't it crazy that we are the only living planet in the whole universe so far?
The last I heard, there are 120 billion galaxies that we know about, each with an average of about 120 million stars, and we have discovered more than 300 extrasolar planets %26amp; more all the time as our instruments get better. Given that, and that we have found liquid water on 2-4 other worlds in our own system (Europa, Encaladeus(sp.), maybe Titan %26amp; Mars), it seems highly probable that there is other life outside our system.
Our technology is best at detecting huge Jupiter-like worlds that rotate close to their stars, but we have detected a rocky planet somewhat bigger than Earth orbiting a red dwarf. This world is the right temperature for liquid water, but it looks like it's in tidal lock (the same side always facing the sun), so water would only be along the twilight fringes.
The above assumes (perhaps falsely) that liquid water is a prerequisite for life. We don't know what other life would look or think like. However, Hollywood usually portrays sentient aliens as having the same shape as humans because of a) human actors, b) they're simpler to animate and c) human audiences can relate to the characters more easily. I believe Stephen Hawking came out with a TV mini-series or something within recent weeks that suggested more imaginative speculations of other life.
There is absolutely no doubt in my mind that there is life elsewhere in the universe. It would be almost ridiculous to think that in the vast expanse of space, there isn't any other life other than our own. There are probably plenty of earth-like planets with organisms which are unique or maybe even similar to those on earth (Though I don't believe planets need to be just like earth to support life). I bet right now at this exact moment, there is an intelligent being on another planet wondering whether there is other life in space. I wish we could yell back and say "WE EXIST".Isn't it crazy that we are the only living planet in the whole universe so far?
We have only obtained the technological capacity to even detect extrasolar planets within the past couple of decades. We still cannot determine if any of them have life on them.
I think we will eventually find life to be abundant in the universe. Considering the conditions necessary for a technological species to develop, I don't find it *terribly* surprising that we have not encountered one yet. There are vast distances involved.
There could be. Out of the trillions of stars any solar systems around them, many of them must have life like ours (trees, lakes etc.).
But if you say is there life on other planets well then there is, bacteria is a form of life and the particles in water are life too. We have basically found life on mars because I believe they have found frozen water or traces of it anyway. To answer your question yes there is defiantly life on other planets we just havn't found one EXACTLY like ours yet.Isn't it crazy that we are the only living planet in the whole universe so far?
I am certain we will find them, or they will find us. The task is overwhelming. Imagine trying to find one particular grain of sand in the entire Sahara desert. Its going to take a great deal of looking with much better technology than we have currently available.
i sometimes wonder about the same thing...and the answer that i get from my head is..who knows..maybe there are other creatures or maybe there aren't!
We ain't the only ones.
There's a lot of Earth like planets around.
