Light Knight : I'm fascinated by Kepler! I follow all the updates on recent Planets found, very similar to that of the Earth's!

Yes, I do think that there is life out there on planets. We just do not have the technology right now to actually know if there is. Someday we will, and I want to be one of the first to discover them!

Light Knight : Its great to hear your interested in the Kepler subjects Light Knight, i personally find it a amazing topic of interest and conversation.

Faith

There are trillions of galaxies in the universe, each with billions of stars in them. At least one in six stars have earth sized planets, and some of them are bound to be in the habitable zone. We've already found planets with the ability to sustain life, such as HD 97658b and Kepler-22b. Really, if we were the only intelligent life in the universe, it would be an awful waste of space. 

epic-san : Yeah, and one of those can contain an Eatth-like planet with live.

I mean... it is possible. But I have not seen any proof of hard evidence, and that is what matters to be. So I vote Not Sure on this subject matter. 

I wouldn't say no on that topic. If there is life on planet Earth, there has to be another planet in the universe that has some sort of life. Maybe not human-life, but plant. You know?

It is Black Bot here, with a LONGER than usual post. This explains a whole bunch of live on other planets in different Solar Systems, in different galaxies. Enjoy.

Do not be so weird guys, There is already proof that there is life in another Solar System on a planet. There IS life. You guys should pay attention to the news more. No offence. 
"Traveling to another Earth-like world just got a lot easier. It turns out that there may be many other dirt-and-water planets lurking at the edges of our solar system in places like the Oort Cloud. These planets, which could be roughly the size of our own, would contain all the elements we need for life. They're just sitting in a cold, dimly-lit part of the solar system, waiting to be defrosted and colonized. Yesterday, NASA scientists announced that this changes the prognosis for nearby livable planets."

There are other planets. This is what I think NASA said.
So all we need to do is haul one of those babies into our orbit, defrost it, and start populating. Earth 2, here I come!

Yeah! So  we just need to do that, somehow..


The observations suggest that between 20% and 60% of Sun-like stars have evidence for the formation of rocky planets not unlike the processes we think led to planet Earth. That is very exciting.

There is a lot more proof that there is life on lots of other planets. The universe is bigger than you think. There is also probably OVER 1,000 planets that have life somewhere in different galaxies and stuff. There is so much stuff in space that nobody knows about. But there is a whole living world way out there and all you need to do is THINK before you say "There is no life out there. I do not believe there is another living world out there."
Sorry for the long post, but there IS lots of life way out there.

THINK before you post people..

Black Bot : And read before you post. Most of what you said was already said by many people, yet you thought most other posters didn't know any of that.

And no, there is NO proof that there is life in an other systems ("Solar" system only refers to OUR system, not others); there is very very strong evidence that there are earth-like planets in terms of size, composition, and distance from their star, but there is no indication of life on them.

The Kepler candidates, (the one's that faithnomore, Dean2k13, and epic-san, and I referred too) are the most likely best earth-like planets, yet we don't have any way of knowing yet if there is life on them.

I do agree that it is very exciting though. I think it's likely there is at least some bacterial/vegetation life on at least SOME nearby planets, one day I hope we make it there.

I think there is life on other plants but just not intelligent advanced life. I think life can be found on similar planets like Earth but that life is in bacteria form or maybe plant life based form. 

The Mars rovers are more and more pointing to the possibility that life once existed on Mars.  Also, Jupiter's moon Europa with it's vast oceans beneath the surface ice is a candidate for life.  With even this bit of possibility that life exists and/or existed elsewhere in our solar system, in all likelihood life--even intelligent life--exists somewhere else in the universe.

Of course there can be. Large universe leaves many possibilities to vast unknown

Do I think its possible? Yes
Does that mean that there is? No

But since life has evolved on the planet we are living on its probably possible that there is some other planet out there which has life on it if not multiple.

But I doubt we will find out anytime soon if ever.

I think there is life on other plants but just not intelligent advanced life. I think life can be found on similar planets like Earth but that life is in bacteria form or maybe plant life based form or even a fungus based life form. Bottom line I don't believe in little green men out there or any for of intelligent alien life. 

I'm a big believer in life outside of Earth. It will be arrogant of us to think we are the only life that exists in the universe because the universe is so large and vast. There could be life outside of Earth in our own solar system. Such as Europa which is a moon of Jupiter which immense gravity pulls on its moons which causes them to be volcanic and Europa has a molten core and covered with ice. Meaning that there could be a liquid ocean underneath all that ice and when there's water there could be life. Life doesn't need sunlight to survive just look at the thermal vents in the oceans here on Earth. I heard years back that NASA wants to send a small probe to Europa and look for ice in the sea of Europa using a small mini unmanned sub. There could still be life on Mars if there was any it would be underground or in the poles where most of the water is located at. 

I don't think so. My opinion would change if we had a legitimate sign, not some hunch, from extraterrestrial beings. Some planets do support life, but that doesn't mean anything. I'd maybe believe it if we saw some tent or settlement on Mars or some other planet man hasn't been on. But, until then, science hasn't proven anything. 

Many people here have said that they would believe it if we saw other lifeforms. But we won't. Think about this. Proxima Centauri is the closest start (other than our sun) to us. That star is roughly 24,792,710,570,269 miles away. When our space shuttles go 17,582 miles per hour (give or a take a few), it would take 12,592,018,293 years just to reach that planet. And if memory serves me right, no planets have actually been confirmed orbiting that star. So the closest planet to our solar system is even farther than that. Now, we can probably make faster shuttles in the future, but light speed is science fiction. Matter can't travel the speed of light without being broken back down to pure energy, so that is a bust. No matter how advanced another civilization on a distant solar system might become, it is just not likely they are going to visit this one planet. Unless there are beings made of pure energy, they can't travel light speed. So unless they are immortal or live hundreds of thousands (or even millions depending on the distance) of years, they couldn't even survive the trip. 

So meeting other life is not in the cards, honestly. But I still think it is naive to think we are the only intelligent non bacterial life. All stars are created the same way. All of those stars go through nuclear fusion at the core. This process is essential for planets to be formed. All planets, both gas and rocky, are formed by the same process. Our galaxy alone contains anywhere from 100-400 billion stars, many having rocky planets orbiting it like ours. What are the odds of all of those, ours is the ONLY one formed an appropriate distance from it's star and have a suitable composition for life? Then when you take into consideration there are more galaxies than we can count, some bigger, smaller, or the same size as our own galaxy. Another planet NOT being able develop intelligent life when there are that many chances for it to happen more than defy chances to the point of nearly impossible.

rcarter2 : Do you mean WE alive right now won't ever see other lifeforms, or did you mean humanity in general?

It is impossible to travel the speed of light, according to the theory of relativity. But how long until we find a new theory that might change that? For example, in the Quantum Mechanics world, it IS possible to send information faster than the speed of light; and while we currently can't conduct those experiments on anything larger than on a quantum scale,  if we find a unifying theory (which is supposedly the next big step in science), we may in time find ways to travel matter faster than light and not suffer some of the consequences, in the very distant future.

Or perhaps we will find an entirely other way of reaching those worlds. Perhaps we will be able to keep humans alive for thousands of years, who knows.

We alive now won't ever see any other life, but if history has shown us anything, it is that humans always make their world smaller and smaller... and planets thousands of light years away is only one more, though huge, obstacle.

And anything humanity can or will do, an other intelligent life form can as well.

Bottom line is, to limit the possibilities for humanity FOREVER based on what we know of science NOW is very naive.

Light Knight : Of course I mean now

But such a leap like that does not happen in one lifetime (heck, maybe even 3 lifetimes). But one thing to consider is resources. We definitely don't have an infinite resource supply, and one of the hot topics is how much we have depleted. Do we even have the resources capable of making said discovery that bypasses what we currently know as the boundaries of quantum mechanics? Given that any star or planet our there is made the same way as ours (unless somewhere someone artificially made a planet ), can any civilization make that leap in discovery (if it is possible) before they lack the usable resources to do so? But the point of all this is that we will nob be discovering life while the current population is alive. Though I believe in life out there, I don't believe a single alien siting story out there right now, and I believe even less the abduction/experimentation stories. If there is other life out there, we are not a special civilization that warrants all other life's attention. 

I agree to limit possibilities forever based on what we know now is naive. But I also consider that the unknown is just that. Unknown. There really are no 'possibilities' per say. In reality, it either is or it isn't. If such things such as FLS, extending life by hundreds of thousands to even millions of years, etc are NOT possible, then we will never inhabit another planet. The planet we have now is it for us and is all we will ever get. If any of it IS possible, then humans will only see it if it is discovered (by us or someone who happens to come here and teach us) AND controllable. 3 scenarios, only one of which ends with us being able to travel to other places out of our solar system. But none of the 3 are actually 'possibilities'. Only scenarios in which only one of them can be correct. The other 2 are irrelevant. But we can't know which one, so one can only hope for the one they prefer.
