Born and bred Buckeye from the Great State of OHIO - GO BUCKS !!!
Nuclear Engineer with a lifetime interest in GR, QM, and the origin and fate of the Universe.
I believe that Isaac Azimov's Robot, Empire, and Foundation Trilogy series is not science fiction, but that it was a gift from the future to inspire our generations.
I have been a member of SETI@Home for about seven years and I first occupied this "pebble in the sky" (Thanks again, Isaac) 73 years after the great man himself, Albert Einstein, joined the human race and forever changed how we view the Universe and our place in it.
If there is not intelligent life elsewhere in the universe today, then I believe there will be eventually, even if that intelligent life is only we humans, expanding out into a Galactic Empire.
If you live long enough, the future will catch up with you.

Based on Frank Drake's famous equation and related data on the GHZ, I have "guess-timated" that there are 469,000 planets with life in our galaxy, of which 12 have harbored intelligent life such as ourselves.
Further, give the volume of the GHZ and the time span over which life and intelligent life can emerge, I have further estimated that these 12 planets capable of communicating with us are, on average, each separated by 64,256 lightyears.
Assuming equidistant spheres around the "torus" of the GHZ, this means about 1 planet harboring intelligent life for every cubic Mpc within the GHZ.
This would, in turn, place 2 of these 12 planets within our sphere of reception within the 100,000 year period that I assume we will exist as an entity to receive such signals.
Given the likelihood of these 2 planets transmitting during our 100,000 years of existence, this places the odds of reception within that 100,000 years at something like 1 in 6 billion.
However, given that the sources of potential error in the above calculations are truly "astronomical", I like yourselves, remain optimistic.
The universe, being as it is, would tend to provide us with proof of such existence by giving us our first, and possibly only, reception within the next 50,000 years. |
