how many think there is other life than us?

Question

i think there is because our galazy is soo tiny in all of the trillions of galaxy's in the universe and we dont even have the technology to travel outside of our galaxy and take a picture of it i say theres got to be other life on one of those trillions of other galaxy's

Answer 1

Suprisingly there is a reasonable amunt of actual mathematics done on this very subject. A physicist called Dr Frank Drake created the 'Drake equation' which actually estimates the number of other civilisations in our galaxy.

The basic equation is:

N = R* x fp x ne x fl x fi x fc x L

Where:

R* is the average rate of star formation in our galaxy
fp is the fraction of those stars that have planets
ne is the average number of planets that can potentially support life per star that has planets
fl is the fraction of the above that actually go on to develop life at some point
fi is the fraction of the above that actually go on to develop intelligent life
fc is the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L is the length of time such civilizations release detectable signals into space.

Drake estimates that N is about 10. Remember that is only for our galaxy and there are millions of other galaxies...

Answer 2

Hey There Cev... Nice to meet you...

I think that there is life out there other than "us."

I also think that it is less than adequate to surmise that this life will be in a form that we can see in our minds right now:
Such as Horses, Birds, Fish, Dogs, Cats, and People. The various life forms here on Earth have evolved due to certain sets of influences over a long period of time which are peculiar to Earth. I think that the probability that those same chemical and physical influences occurring in exactly the same sequence over the exact same period of time is highly unlikely in the extreme.

For example: The Earth, according to various scientists, is between 4 and 5 Billion Years old. Yet the intelligent life that we are familiar with (developing space ships, sending remote control radio signals and probes to the distant planets, developing the early stages of human and animal cell cloning, and investigating the inner workings of the atom...those things have only happened within the last 100 to 200 years of Earth's existance. And while making some miraculous discoveries, mankind has also developed enough weapons to totally kill every living thing on the surface of the Earth.

So, what is to say that when we find some earth equal planet, that planet has reached a similar and parallel stage in its development as the Earth has reached? Really, we could miss the mark by a billion years, or so. If that were the case, which seems entirely likely to happen, would you then say that there was no intelligent life there? Or, would you agree that it just hadn't happened to develop there yet? Maybe some terrible disease wiped out all life there long, long ago. Are we to then suggest that there is/was no intelligent life there?

Now, coming right to the point... Are you willing to concede the point that intelligent life forms on a distant planet in a foreign solar system might indeed be extremely smart birds, fish, or some kind of insect? The probability that the life forms which developed on this remote earthlike equivalent planet might be humanoid in form is really quite small.

Answer 3

We barely have the ability to send probes beyond our own solar system, forget about leaving our galaxy!

The idea that there might not be life outside our planet comes from the same human-centric viewpoint that allowed us to think that the Earth was the center of the universe.

It is highly unlikely that we are on the only planet with life on it. Even if we never discover other life, that won't mean it doesn't exist. Only that the universe is too large for us to search effectively.

Answer 4

I think it's possible

even in our MIlky Way galaxy there are 100 bln stars like the sun and it's very possible that at least there is one planet with the conditions for existence of life

and besides the MIlky Way there are some trillions galaxies in the universe

Answer 5

People don't like to think about this because if we aren't alone, thousands of religious beliefs are destroyed. But of all the millions of planets in an "endless" universe, how can we be alone? There are others somewhere.

Answer 6

I believe that there is other intelligent life out there because of the sheer number of stars and planets rotating around them. I believe that we just can't be the only intelligent life in the universe.

Answer 7

There is certain to be other life forms in the universe but the great divergence of paths that evolution can take in other places leaves me to believe that we are probably unique.

Answer 8

Yes I agree for what is worth . There is a big problem that we are so far apart that there is very little chance that we would even be able to communicate with each other.

Answer 9

im a gambler, and odds are in our favor that theres more life out there.

Answer 10

Yeah sure is. Trees, birds, bacteria, virus, etc etc etc
