ETI, and the formula
to calculate the number of extra terrestrial planets capable of supporting life.
I know there is a mathimatical formula to calculate the number, but I cannot remember the name of it, if I ever knew it.
Can anyone tell me what the Name of the Fomula is? Or where to find it online?
I am continuing a debate begun several years ago with an old friend, and a new friend online, need more ammo.
