Theres actually a mathmatical equasion to answer your question:

 

 

N is the number of civilizations in our galaxy with which communication might be possible;

and

 

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.

 

This is known as the Drake Equation

 

Plug the numbers in and you'll know how much life is in the universe. :-P

 

The general accepted answer amung people who believe this could be a good estimate is:

 

N = 7 × 0.5 × 2 × 0.33 × 0.01 × 0.01 × 10000 = 2.31

 

So estimated value, theres 1 other inteligent civilization outside of us somewhere in the universe.

Ok, teacher Mr. SpikedRocker

wow thats actually pretty cool!!!

[Justice...]

lol, you cant determine wether its 1 or 2 or 4 or 1000 or 0 other intelligent species out there by math. I mean, you just cant.

[Itch]

Sure you can.. supposedly there is an infinite number of planets out there.. and a finite number would be inhabited.

 

So if you divide an infinite number by a finite number the result is too small to be calculated.

 

Thus total population = 0 and we don't exist.

NERD Jk dont hurt me

I heard that they discovered a frozen lake on one of the planets that could support life.

You are talking about Europa. It's one of Jupiter's moons and the outer layer of it is a thick layer of ice since the planet's surface is about -276 degrees celcius (Off the top of my head). Underneath that ice is a vast ocean which is warm enough to support life.

 

This reminded me of the philosophical thread that I still need to reply to, hehe.

so, because the math says so, there is us + 1 more intelligent race out there? Naww dont think so =)

The key thing here is these are estimations. Obviously its nearly impossible to count all the galaxys, stars, or planets and determine if they are in the habitable zones. But these are mainly estimations that gives people hope to finding intelligent life.

Europa has probably the most realistic source for life elsewhere in our solar system. Granted the surface is near absolute zero temperatures, but due to possible vulcanic activity in the core and Jupiters massivly strong magnetosphere causing crazy radiaton its possible about 100 miles under the surface there is liquid water. It hasn't been proved obviously no probe has drilled but its most likely to have it.

 

The life forms on Europa are most likely non-inteligent but they would be considered life. My suggestion to anyone interested in stuff like this should catch "The Universe" on the History Channel...they have a whole episode dedicated to this.

seen it befor but its all theoretical but it would be stupid to think there aint life out there
