Question 22

Question: Does technological capable life exist in this universe or any other universe? –aaron

Answer: If I knew the answer to this I would be famous. I will say this though:

I believe in the Big Bang Theory and evolution based on the findings and research I have read. In doing so, this affords the opportunity for intelligent life to exist on other planets. Obviously I am not the first to think this. There was a fellow by the name of Drake that is famous for his attempt to estimate the number of extraterrestrial civilizations in our galaxy with which we might come in contact. It is called the Drake Equation and looks like this:

N= R* x fp x ne x fl x fi x fc x L where N = the number of civilizations in our galaxy that we might be able to communicate with.

    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
Current estimates and measurements put the values for this at:

    R* = 6/year, fp = 0.5, ne = 2, fl = 0.33, fi = 1×10-7, fc = 0.01, and L = 420 years
    N = 6 × 0.5 × 2 × 0.33 × 1×10-7 × 0.01 × 420 = 8.316×10-7 = 0.0000008

So that means that the chance of another intelligent civilization in our galaxy is slim. But with billions of galaxies in existence, the equation starts to yield more interesting numbers. There can be literally thousands of intelligent civilizations in the universe.

To answer your question aaron, yes I believe it is possible for others to exist, but like the existence in God, I need proof.

But I will add this… There have been more sightings of aliens than there have been of God ;)

    for more info, see:

    But, let me add to that, there is more then one galaxy, and all those values are under constant discussion. Also, it doesn’t say anything about races that are allready gone/aren’t here yet.

    now, wether or not these aliens would take an intrest in us, is a different question.
