Obviously if there is any life elsewhere in the galaxy, it's alien, and probably looks nothing like us. But seriously, if there is life out there somewhere, even if it's intelligent, who know's how far along they are? Even if they have superior technology, the vastness and harshness of space is a ridiculously hard thing to overcome. I mean, the closest star to us (Proxima Centauri) is 4.24 light years away. Light travels at a speed of 186,000 miles a second, or 700 million miles an hour. Think about that. Traveling that fast, it still takes over 4 years just for the light to reach us from that star. Now imagine how long that would take when traveling in the space shuttle, even using it's orbit speed of 17-18,000 mph. Then you have to figure out how to store all the fuel you'd need, which in turn calls for a much, much, much larger spacecraft to hold the fuel. There are all sorts of possible designs, but they use imaginary technology that won't be around any time soon, if ever.
Now try to imagine that that intelligent life is in a totally different galaxy, somewhere on the other side of the universe, where distance would be measured in thousands upon thousands of light years. The distances are almost impossible to fathom. Unless someone discovers how to convert anti-matter into fuel, or stumbles upon a wormhole (which is still just a theory at this point), humans won't be making contact with anybody that lives on another planet outside our solar system.

Man o man, this question i've asked ALL my life. I definetly believe there is other life, there HAS to be. Once i learned that what we see at night, the stars and stuff, and all our planets-are inside OUR galaxy, and beyond that, there is countless other stars/galaxy's/planets etc it got me thinking. The aliens..well i believe most of them would be human-like, nothing like crazy 8 headed monsters, or friggin predator's etc-then again, thats selfish by me stating that, cause i just don't know.
But yeah, this question is just amazing.. Cause it's the biggest question posed next to the whole God and Heaven thing. I believe in god, and heaven-but remember, if there is a good, there is an evil.

Okay lets say for the sake of argument, there is life out on another planet in the universe somewhere. How can you say that they would be human like. We as humans have evolved because of our genetic makeup our gravity and the environment and millions of years of evolution Whats to say that on that other planet their gravity is different or the astmosphere etc. The species would evolved probably shorter, thicker skin (if the environment was harsher compared to ours) etc, etc. I believe I saw in one of those science mags a long time ago this same scenario and the creatures they came up with were mind boggling.

Not one sign of life outside our little rock in the universe. Nothing.
With such a total lack of evidence, I'm surprised at the number of people who believe that there is life out there (especially intelligent life). It would be amazing if there was, but consider a few things. The universe is 15 billion years old (give or take). It took (supposedly) about three billion years for humans to show up. We only took a tiny fraction of that time to invent radios. Our radio waves will be loud enough to hear on the furthest galaxies we know of once the waves get there. All it would take is for one species to develop radio waves in the last ten billion years for us to pick up on them. Even if a species took tens of thousands of years to go from planet to planet (even with only probes) they could have covered the galaxy a hundred times over.
The fact the vastness of space makes it hard to find things is offset by the magnitude of time we’re dealing with.
Not one piece of evidence – anywhere.

They are supposed to be 6ft tall, weigh no more than 120lbs and have what earthlings call "blonde hair", oh, and they have mounds or some kind of foreign rubber-like domes in there chests....

lack of evidence how can you even say that. Seriouly yogs i though more of you. there are plenty of pictures showing extremelly low resolution blobs in the sky. Plus all the eye witness accounts from angry drunk inbred rednecks.
And lets not forget the lights in the sky as also seen in very low resolution videos. How can you explain those except for the airplaines of all types, helicopters, meteorites etc.
See plenty of evidence. Heck maybe I'll get drunk tomorow get my ultra hight tech camera (5 pixel rez) and take some more pictures of them aliens.
FYI is a proven fact that hight alcohool levels in the blood, combined with the use of 3 dollar cameras found in albertson's discount bin increase the chances of witnessing an alien. Just remember to use the worst posible lighting, shaky hands and the walmart 50c foto special when you develop them.

Even if a species took tens of thousands of years to go from planet to planet (even with only probes) they could have covered the galaxy a hundred times over.
You're forgetting that there is no 'sound' in outer space, so the "loudness" of our radio waves is irrelevant. Not to mention, who's to say that an alien civilization would even be monitoring for radio waves? Maybe they're so advanced they don't bother with such an inferior technology, and instead use something stronger or faster. They could be broadcasting at a frequency or using a method we aren't even aware of it. Or maybe they haven't even reached the basic radio level yet.
The label of 'intelligent life' doesn't apply only to modern day humans; it also covers our early ancestors who were making primitive cave drawings and using the most basic of stone tools, and probably couldn't even imagine some of the things we have today, as well as another group of primates, the chimpanzee.
Also, there is no way a space probe could cover the universe a hundred times over, even if it was travelling for "tens of thousands of years" as you put it. A galaxy? Possibly. I'm not going to bother with the math on that one, lol. There are at least 100 billion galaxies, each with approximately 1 billion stars. Even travelling at the speed of light, this would take a ridiculous amount of time. The universe is at least 156 billion light-years wide, based on this study. (http://www.space.com/scienceastronomy/mystery_monday_040524.html) And like i said, that's if you're travelling at the speed of light. Now take into account that radio waves and the like travel nowhere near as fast as light does, and you can start to see how hard it would be for humans to make contact with another culture somewhere in our own galaxy, let alone one in another galaxy, or in a distant corner of the universe. It takes a looooooooong, looooong time for things to travel in space, even if a civilization is more advanced than ours. Aside from travelling at light speed, the only way (theoretically, at least) to travel quickly across the galaxy, is through a wormhole. Assuming these do exist, an alien culture would have to be sophisticated enough to not only find one, but also intelligent enough to use it properly.
The odds are in favor of there being life out there somewhere. Whether it ever advances to the point we're at now, or is ever able to contact us, who knows? They/it could be wondering the same thing. And what that lifeform might look like, that's anybody's guess, and using your wildest imagination certainly wouldn't hurt in this department. Just take a look at all the varied types of animals we have living on land. Now factor in all the life forms that live in the oceans, some of which live in environments that were once thought to be completely inhospitable to life (deep sea vents, for example). But in fact, life flourishes in those environments. Life adapts to whatever conditions are present. Life elsewhere in the universe may look somewhat familiar to us, or it could look like nothing anyone has ever imagined.

Oh my goodness. Please tell me you're only 13 years old or so. :disappoin The radio wave is just like any other light wave. Though you can't see it, the broadcast off the Earth is brighter then the radio waves produced by the rest of the galaxy. Irrelevent? What the heck do you think all the searchers are looking for? Flashlights?
Not to mention, who's to say that an alien civilization would even be monitoring for radio waves? Maybe they're so advanced they don't bother with such an inferior technology, and instead use something stronger or faster.
You must not understand anything about the laws of large numbers. Keeping it simple, the fact is that humans went from stone tools to radio waves in a hundred thousand years. The age of the universe is on the 15 billion year range or so. If you consider the current estimates of 200 billion billion potential systems out there, don't you think at least a couple of planets out there would use radio waves?
They could be broadcasting at a frequency or using a method we aren't even aware of it. Or maybe they haven't even reached the basic radio level yet.
The method is irrelevent. The frequency is everything. Radio waves are in the best position of the electromagnetic spectrum to broadcast information over long distances. Microwaves and visible light can't penetrate solid objects. XRays and Gamma rays are damaging and expensive to produce (though we'd see an xray source if an alien civilization were using them).

You just don't get it. Do you know what an airport hub is? Planes land and fly off in different directions. They land at a different hub and then take off from different directions again. This is not a linear equation. Even using the slow rockets we have now, we could populate the entire galaxy (if there are planets to hold us) in several million year. That is a drop in the bucket to the age of the universe. Yet, we see no signs that anyone has done that. Nor do we see any signs that anyone has done it in another galaxy.

yeah 8 min your right
we did find evidence of microscopic life on mars, fossilised, but still. Humans and other modern day intelligent life evolved from unicellular life on our own planet, so considering that there was at one time flowing water on mars it is very possible that life couldve bloomed on that planet as well had the resources not been whiped out by enviornmental factors. This alone obviously doesnt say much about the entire universe, as mars and earth are very close to each other when you think in terms of the entire universe. But considering that we know that many other planets far outside of our solar system have the exact same elements that we have on earth (not necessarily all of them, or mabe even more than us, but elements such as sulfur exist on on planets throughout the universe in the exact form which exists on earth, so i believe that it is very possible for other planets to have conditions capable of supporting life, and it is possible that life would actualy come to exist on those planets, especialy given the time frame. Life could have blossomed and evolved millions of years beond us, and been whiped out before the first sign of life on our own planet.
edit: after reading it i just want to clairify that i do not believe that there is definately life outside or our planet, just that there is a possibility for intelligent life outside of earth.

there is believed to be less than 20 intelligent life forms in the universe, including us. just went over this in school yesterday. and that is only to be thought, not even for sure. we could possibly be the only intelligent life forms out there.
a philosopher once said no matter which way you look at it, whether we are here alone, or with other species its pretty scary.

Gee, i never stated anywhere that i was an expert on astronomy or space travel. Of course, if you're such an expert then why are you still on this planet? I never said that space was a straight line either. Did you even read the information contained in the link i provided? The purpose was to illustrate how large the universe is, not what shape it is (which no one knows for sure, by the way). Also, since it seems you either didn't read it, or just didn't understand the article, i'll post this to enlighten you:The universe is about 13.7 billion years old. Light reaching us from the earliest known galaxies has been travelling, therefore, for more than 13 billion years. So one might assume that the radius of the universe is 13.7 billion light-years and that the whole shebang is double that, or 27.4 billion light-years wide.
But the universe has been expanding ever since the beginning of time, when theorists believe it all sprang forth from an infinitely dense point in a Big Bang.
"All the distance covered by the light in the early universe gets increased by the expansion of the universe," explains Neil Cornish, an astrophysicist at Montana State University. "Think of it like compound interest."
Need a visual? Imagine the universe just a million years after it was born, Cornish suggests. A batch of light travels for a year, covering one light-year. "At that time, the universe was about 1,000 times smaller than it is today," he said. "Thus, that one light-year has now stretched to become 1,000 light-years."
All the pieces add up to 78 billion-light-years. The light has not traveled that far, but "the starting point of a photon reaching us today after travelling for 13.7 billion years is now 78 billion light-years away," Cornish said. That would be the radius of the universe, and twice that -- 156 billion light-years -- is the diameter. That's based on a view going 90 percent of the way back in time, so it might be slightly larger.
"It can be thought of as a spherical diameter is the usual sense," Cornish added comfortingly.
(You might have heard the universe is almost surely flat, not spherical. The flatness refers to its geometry being "normal," like what is taught in school; two parallel lines can never cross.)
This is the kind of thinking that leads to wild speculations.
Yeah, imagine that. If it weren't for wild thinking and speculation, we'd still think the earth was flat, or that the sun revolved around earth. Wild thinking is what leads to scientific breakthroughs, and new technologies. It's called thinking outside the box. Maybe you should try it sometime when you pull your high-and-mighty head out of your ass.

the SUN (bright thinngy in the sky :smile: ) is a star, bud, about .02 light years away i believe i donno, 7 days is the number ive been hearing as far as light from the sun reachnig us so i figure thats at least close
Duh. Obviously i was referring to a star outside our own solar system. :loser:
I should just list off the topics you need a lot more study in, but suffice it to say that space is not a straight line. The universe is not 156 billion light years across. If it were, then the universe would have to be 156 billion years old and the laws of large numbers would still be in play and there would be an entire factor more to deal with.
Gee, i never stated anywhere that i was an expert on astronomy or space travel. Of course, if you're such an expert then why are you still on this planet? I never said that space was a straight line either. Did you even read the information contained in the link i provided? The purpose was to illustrate how large the universe is, not what shape it is (which no one knows for sure, by the way).

just out of curiosity, how did your teacher/textbook justify its prediction that there are ~20 intelligent life forms in the universe? im having trouble believing that they could find anything solid behind that, and it kind of sounds like a bs estimate.

This is where you are mistaken. Yes, sound waves do travel through space. Yes, they can be detected by whatever creature on whatever planet provided they have the equipment. However, you can't actually hear the sound of whatever it is you are trying to listen to if you are in outer space. For example, if you were to clap your hands in space, you would see your hands smack together, but there would be no sound picked up by your ears (that is, if it were possible to be in space without a pressurized helmet), because our ears simply are not sensitive enough. For humans to actually hear sounds in outer space would require an amazingly large and sensitive microphone to pick up the sound waves, which would then need to be processed and transmitted to our ears through headphones.
That being said, perhaps it is you who has the IQ problem, or got a poor education at whatever institution you went to, because this is stuff i learned in grade school. Before you open your mouth and stick your foot in it again, why don't you try and learn about a topic before you attempt to make fun of someone? If i didn't know what i was talking about, i wouldn't bother posting.

:disappoin What a sad little boy you are. Wild speculation is not how theories are made or discoveries are found. Speculation is not thinking 'outside the box'. That is a phrase made up to sell consulting time. Discoveries are made because someone spends the time to decipher a mystery. They come up with tangible evidence or mathematical proof. That proof is presented and debate can begin on its validity. You cannot find a single reputable piece of evidence that life outside this planet exists. None. Not one. Every single model proposed is built solely on conjecture.
I've suggested you learn about the law of large numbers. I suggest you read Cosmos. I also suggest you read 'Aliens Cause Global Warming' by Michael Crichton.
You are a classic example of someone who thinks they are a whole lot smarter then they really are. You should pull your own head out of your ass and wipe the shit from your eyes and you might just see that my original response to you was an effort to give you additional information that you could use to expand your knowledge. Its amazing that Hawkins, Lane and Sagan couldn't propose a workable model but armchair physicists can.
No evidence has been found. No workable model has ever been produced. Believing that aliens are out there has less empirical evidence then the existence of God. Proofs are never done to prove the negative and until something is found or a positive model is found - The existence of extraterrestrial life is speculation at best, no matter how hopeful we may be.
As for your last response to leadfootGTP - :rofl: you really are uneducated aren't you? Hear sounds in space by clapping hands? Do you even know how sounds are transmitted? The slightest idea? You have an opportunity here to shut up and do some actual research. The hole you are digging for yourself is just getting bigger every post. That or you need to go back to grade school and pay attention (or those teachers should have been fired).

You are absolutely right; however i didn't mean to imply that speculation is proof unto itself. Hypotheses are not always made because proof is found first. Sometimes it works that way, sometimes it doesn't. But most times hypotheses are produced, and then testing and research, etc. is done to prove it right or wrong.

Exactly. I don't know for sure if life exists out there or not, and neither does anyone else. It's just my opinion that it probably does. No where have i posted that life outside of that on earth exists for sure or doesn't, or that there is definite proof one way or the other. And as far as there being less proof that aliens exist compared to a god, gimme a break. There is no more evidence to prove/disprove the existence of either. At this point, they're both in the same boat. Some believe, some don't, but there is absolutely no evidence to prove either camp's belief.

Dude, look back to my original post. I said that you cannot hear actual sounds in space with your ears. I didn't say that sound waves are non-existent. I was merely giving a very simple example of how you could do something that on earth would produce a noise you could hear, but in space there would be nothing. Obviously the sound waves are still created, but as i stated in my followup post, it would require and amazingly large and sensitive microphone to pick up the waves, because our ears are not sensitive enough by themselves. Why don't you look it up instead of just assuming you know everything?

There are no sound waves. There are not enough connected molecules in space to provide the vibration needed to make sound.
I'll provide a link to help you out since you seem unable to grasp it, I'll keep it simple. http://www.qrg.northwestern.edu/projects/vss/docs/space-environment/1-is-there-sound-in-space.html

You are well into your 20s if the bday in your info is correct, given your posts that is the saddest thing I have ever heard. Im done with this thread, reading your posts is dropping my own iq substantially.
By the way, we didnt discover that the earth was flat with "wild thinking" we noticed the way that ships came slowly into view starting at the top of their sails and great minds hypothesised and tested their theory that this meant that the world couldnt be flat.

OK, first of all if you travel a long time at the speed of light you are not getting old (Einstein said that than living tissue doesnt get old) Than in all of that neverending space there HAS to be something living. It is impossible that humans are only life, when the Earth finally collapse what there would be no life until another Earth exidantly form (wait I just created another hypothesis, sweet) anyways that might be case. I don't think any of us will ever find out.
This question is one of the things I think we ll never know.

Without getting into deep analisys of relativistic mass vs rest mass. The mass does increases. Any object pushed with mass pushed to lightspeed will have infinite mass. This is why its imposible. Only 0 Mass particles such as the photon can acheive light speed(as measured in vaccuum).
Weight is mass times gravitational accelleration. This is why you weigh more on juper than on earth even if you mass stayes the same.

My thoughts exactly Dantheman. What is infinity? (Don't say a car). So you probe as far as you can into the universe. Then go farther. Repeat. There is no end to it. Now it might be contained in a marble, like in Men In Black. But those aliens, they're got their planet, and outside that, to the end of what they can probe, then .... there's more.
Yogz, I agree there isn't any hard evidence that other life exists out there. But there is an infinite area in which conditions may exist that life could form in. Infinity's mighty big, so I wouldn't rule out little green men just yet.
But no matter what, you still can't hear your hands clapping in space. Um, why was Jas_M banned, anyway?
