What major scientist think about this possiblity? why?

Question

Thsi question is about is there life on other planets i need this for a project soon thanks

Answer 1

Check out the equation posed by Drake:
It goes a little like:
N = R × fp × ne × fl × fi × fc × L,
Where N is the number of civilizations we can expect to try to communicate with us.
R is the rate of star formation in our galaxy,
fp is the fraction of those stars that have planets,
ne is 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,
fi is the fraction of the above that actually go on to develop intelligent life,
fc is the fraction of the above that are willing and able to communicate,
L is the expected lifetime of such a civilization.

It's fairly famous, but I don't see much use in it since most of the variables are hardly guessable.

Answer 2

If you mean in our solar system, we still haven't found any. I have to say after all this time that it seems like if there is, it's already all dead.

As for any planet in the universe, I'd say the odds are 1 (in other words a definite yes) that there is life on some planet somewhere.

Answer 4

The jury is still out until we have some positive evidence. However, it is unlikely in the extreme in my opinion that there isn't some life somewhere in the vast universe.
