life , but not as we know it?

Question

do u think it exists elsewhere? if so in what form?
if we are talking about inteligent life...how advanced do you think they wil be? will it be millions/ billions of years the difference?

Answer 1

Does life exists somewhere else in the universe now? Probably
Has life existed somewhere else in the universe ever? Most certainly.

Intelligent life? Depends a little on your definition of intelligent life. If you mean "intelligent" by human standards, I can't see why not. It must be difficult not to be. Have you listened to our politicians? But, if they're "millions/billions of years" ahead of us... they are going to be incredibly benign, or we had better watch out.

If they're benign, they've learned to live in harmony with the universe... just as the dolphins and whales have learned to live in peace with their environment.

But if they're not benign, they'll have survived millions or billions of years by being tough. If they want us to be their friends, we'd better be their friends... and on their terms. Look at us. We're about as mean and belligerent a species as one could imagine. Lacking any other enemy to kill, we kill each other.

What will they look like? Depends on where they come from. If they come from a low gravity planet, they might be tall and rather fragile. If they come from a planet with a strong gravity, they cold be flat, maybe like a fried egg, and if they have a skeletal structure it'll be VERY robust.

But, if any species wants to contact us, they'd better hurry up. We're not going to be around much longer. We're going to have a war that ends life on this planet. Or we're going to over-populate, over-develop, and over-pollute the planet beyond its ability to sustain life. Will we be around another hundred years? Possibly. But we're having a war every 10 years. In 100 years, that'll be 10 wars. One of those will get out of hand. 500 years? Maybe not. 1,000 years? Unlikely. 5,000 years? I'd give us about a hundredth of a percent chance.

Answer 2

Any life is almost surely going to be carbon based. The carbon atom is so amazingly versatile as to make the closest runner up, silicon, a nonstarter. While the drake equation seems to indicate that there are perhaps many thousands of civilizations in the galaxy, SETI has heard no signals from anyone. It could very well be that interstellar travel is impossible since the distances are so vast. If thats the case then we will probably never know if we have company in the galaxy. If interstellar travel is possible, where are they? That is the Fermi Paradox. If it is possible to build an Von Neumann self replicating interstellar probe it should be possible to colonize the galaxy is perhaps 5 to 15 million years. But there is no sign of anybody having visited us.
Another possiblility is the Rare Earth Hypothesis: life is abundant in the cosmos, just simple. Advanced life like our own eukaryote cells, may be EXCEEDINGLY rare. We may very well be the only intelligent life in the galaxy, or perhaps in the universe. The rest of the universe would be populated with yeasts, algae, and moss. It explains why the skies are silent and why we have no visitors. If you are interested read the wikipedia articles on rare earth hypothesis and the fermi paradox.

Answer 3

Man has been hoping that he is not alone in the universe for ages, just as he hopes there is something after death. Seems man can't bear the thought of being alone or of being mortal.
I am sceptical about intelligent life out there. Look at the incredible coincidences which lead to life on Earth. Some 4 billion years ago hundreds of rocks were whizzing round the sun, colliding and forming larger & larger rocks or "planets". One day two of these "planets", of by chance similar size, collided, which by chance, throws them into a favourable orbit round the sun and which, also by chance, gives this new planet a crucially larger molten core than the suns other satellites. This larger core creates tectonic plates without which life wouldn't exsist. Just by chance we have a moon, just the right size & distance away to allow life. All these coincidences allowed bacteria to form which allowed oxygen to form with just the right gasious atmospheric layers to protect life on this shining blue gem in a vast, violent, splendidly awesome universe! The coincidences go on & on. So let's just imagine for a moment that we are the only itelligent life in the universe. Why are we so intent on self extinction, pollution, over population. If we go the same way as the dinosaurs who will be there to witness the marvels that the Hubble telescope has shown us? Guess it doesn't realy matter, the universe will endure wether anyone is there to witness it or not.

Answer 4

1. Yes, I think that life can form anywhere on any planet...

2. It can be in any form, It can be liquid, it can be in rocks, it can be attached to land or something else.

3. They can be sufficiently advanced to see us.

4. Well, the minimum difference is 40 light years and maximum 1 million light years away.

But, as we know,
There are no real straces of life are found. It is not right to imagine them like us..
There can be vast differences between them and us,
for it, we need vast telescopes and the imaginary mentality.

Answer 5

i think that there are other planets that have "aliens" but they're actually a lot like we are. if ufos are real and they've mastered that they must be pretty smart though so i'd say they're more intelligent or advanced than us. i dont know about the ufo thing just a thought. but i do believe there are other planets with life similar to humans but adapt to their environment. either that or we're all sims and a more intelligent race is controlling us. 0.0 sorry its still early.

Answer 6

i believe our human race is not too far from achieving crew operated star travel. our scientists are on the brink of discovering how to travel through worm holes and in to parallel universes. and that's if they haven't discovered it already. but the rate technology is growing i believe it would take 50 to 200 years for mankind to go galaxy hopping : ) how fun!!

with that being said... their are star systems much older than ours with planets around them much older than ours so i believe that life on other planets defiantly exist in many forms but mostly humanoid.

so life on other planets can range from about 200 years older to lets say the beginning of everything. beings that can control the atmosphere of their planet, beings that can control their solar system, and even beings that can create life on new planets just as they did ours. if we were created in the image of god than it means we can be gods to other life forms. we will just continue what we do best...CREATE!!

peace

Answer 7

yes life does exist on many planets in this universe. they are far and way ahead advanced then we are( in inteligence). they are already on their way to earth. (no jokes at all) i will not disclose anything more than that as it is my research material.

Answer 8

According to an article in Scientific American, it might even be alien life on earth right now. See the link below.

Answer 9

Life is great

Answer 10

If it doesn't exist, the universe is an awful waste of space.
