Life in space?

Question

Is it possible that land dwelling creatures, such as ourselves, are very rare in space, that being if there is any other form of life out there? For instance, the nearest planet that could possibly harbor life is covered in ice, with an ocean of water running underneath it. If this is the case, do you think it is possible that intelligent life out in space, would not nessicarly be found on a planet like earth, but instead it would be found underwater? Isn't it true that we find life in water first?

Just looking for some opinions on this.

Answer 1

If there are 1000 billion Stars in the Milky Way Galaxy, and hundreds of thousands of other galaxies with billions more Stars in them, then it is entirely likely that there is a parallel world like ours (Earth), or more than one of them. This does not necessarily mean that that equivalent planet orbiting around some distant star is equally as old as the Earth (or young as
the Earth), nor does it mean that possible life on that equivalent planet is in exactly the same stage of intelligent life form development as ours is. Because the Earth is now about 4 Billion Years old, and intense scientific developments have only occurred in the last 100 years or so, the chance that the intelligence development is equivalent (theirs and ours) is hugely remote. That is to say, the life posessing planet could well be in its dinosaur stage of life form development while we are as we are today. Or, take the converse situation... Man could have developed there a long time ago and due to disease, famine, climate change, or some major event all life forms were wiped out.

Keep in mind please that some of the possible locations we are discussing are tens, hundreds, thousands, even millions of light years away from us. So, knowledge we are gaining about their possible radio or electromagnetic radiation patterns (when we find a significant one) will be thousands and millions of Earth years old, having traveled a long, long distance to reach our receiving antennas and equipment. Further, if you look at the
total age of the Earth and the total age of mankind (from cave man to modern man), man has only been around for the blink of an eye in that total time span. The task is to catch some place that is blinking just like we are...and that is a huge, huge task indeed.

Answer 2

Of course there is life out there, it would be extreamly ignorant to think otherwise, considering the infinant amount of stars out there, and all the planets that we have already discovered orbiting these distant stars... the possibility of life out there is just too great to ignore, and as far as "radio signals", they probably wouldn't use radio signals in the bandwith that we are accustomed to, the most likely would use a form of short wave frequency bands because short wave radio frequency waves travel at the speed of light, but they would most likely focus these radio frequency waves through a gravity amplier which would cause the radio waves to travel much faster than the speed of light, and hence if they were trying to communicate with other species throughout the galaxy than this would be the most logical means of sending radio waves great distances in a relativly short period of time.

Answer 3

ABSOLUTELY!!!!!

My logic on this is simply by looking at my own planet...all of the myriad and millions of individual creatures on it! Look up at the sky....you can see the "billions and billions..." of stars and other Universal entities that Carl Sagan espoused so elequently about!
So, there ARE other stars, planets and life out there, after all as far as I am concerned!

Now whether they WANT to venture out of their comfortable little worlds to find us or not.....that may the most intellegiant thing about them - that they don't - LOL!!! It is interesting to wonder about other races & other lifeforms living in what we call "uninhabitable" envirnoments, what they look like, eat, how they live, love, children..

We have been visited by extraterrestrials - too many people in the world past and present have seen too many things in the skies above Earth, not to believe....but...most CAN be explained or are hoaxes.

There has been spores found at some of the meteorite crash sites around the world (Russia in particular) that posess life not of this world.. Perhaps that's how we came to be...Food for more thought!!!

Answer 4

I take it your talking about Venus being covered in ice. Well keep in mind that our solar system is so tiny in this immense universe, that chances are there is a planet just like earth out there somewhere. As for life underwater, well wouldn't they be fish? It would be interesting to find some new animals but I think everyone would be hoping to find something a little more intelligent , like ourselves. Or maybe we have just seen too much star trek!

Answer 5

Definitely. They might be a little different from us but they are there. It is only a matter of time that we get to know about them. You may refer to the following article
Searching for life in outer space
Monday, March 17, 2003 Posted: 12:00 PM EST (1700 GMT)SAN FRANCISCO, California (Reuters) -- Using 4 million computers worldwide, scientists based at the University of California, Berkeley said that they have identified about 150 sources of possible signals from intelligent civilizations.

The California researchers plan to head to Puerto Rico this month to use one of the world's most powerful telescopes to more closely investigate the signals that might be from extra terrestrials, a university spokeswoman said.

"They are homing in on interesting signals," said Sarah Yang, a spokeswoman at the University of California, Berkeley where the SETI+home research project is based. "They have not said they found anything."

Linking computers
The project links volunteer computer users into the researchers' efforts to search for strong or unusual signals from space that one day may lead to the proof that there really may be something else out there.

The leading candidate signals compiled over more than three years of work are the ones that were particularly strong or have been observed in the same spot more than once, researchers said.

While scientists involved in the project are cautious about their chances of actually discovering a signal from an intelligent being in outer space this time, they believe they are on the right track for the future.

"I believe that we will likely discover extraterrestrial civilizations in the next hundred years," Dan Werthimer, chief scientist of SETI+home said in a statement.

"Even if we don't find a signal from ET this time, I'm optimistic in the long run, since our search capabilities are doubling every year."

Answer 6

there different theories about this,may be we can find super intelligent creatures in outer space,bcoz science hasn't even studied one fourth of outer space and also so little knowledge about life there is with us,yeah traces of water and other samples reveal that in some kind or another life exist in outer space.time will tell what exactly is there,many new research and investigations are on to find the truth.

Answer 7

The conjecture is that life on earth started in the sea so it has a good chance of being correct. Whether it's intelligent life is a whole other matter

Answer 8

I believe you are talking about the moons of Neptune / Jupiter..
Yes, life could be found in the under ice seas of these moons..
I don't know that it would be intelligent but it may be life...
If faster than light travel is indeed impossible then we may
never meet other intelligent life in the universe..

Answer 9

How can we expect to find intelligent life on other planets when we don't even have it here on earth ?

Answer 10

Yes
