The other thread asks about life in the universe. How about the [correct application of Drake's equation] number of planets in the galaxy that support intelligent life?
The discussion revolves around estimating the number of planets in the galaxy that could support intelligent life, referencing the Drake equation. Participants explore various perspectives on the likelihood of intelligent civilizations existing in the galaxy, the definitions of habitable planets, and the implications of these estimates.
Participants express a range of estimates and opinions, with no consensus reached on the number of planets that could support intelligent life. The discussion includes both speculative and critical viewpoints, indicating ongoing debate.
Participants' estimates depend on their definitions of habitability and intelligent life, which remain undefined and subjective. The discussion also highlights varying interpretations of the Drake equation and its application.

Yes that would have been better. But if even a complete guess, a number is nice to contemplate.Originally posted by LogicalAtheist
My point is that people probably think a percentage of planets which have life.
Honestly I make no claims about the %. All I can say is universe large, must be life...

10^10 is a bit exhagerated as the amount of planets in
our galaxy, don't you think ?
If you mean habitable for US planets in the
galaxy (by habitable I assume you mean we'll need
nothing more than cloths to walk around, in the
long term too) then I'd say about 1,000.
If you mean planets that COULD support in a similar
way all the intellegent spiecies that exist
in our galaxy (which I estimate at a few hundred)
then considering their enitial development biological
"form" I'd say about 10^5. (I say their "enitial
biological form" because most intellegent spieces in
the galaxy are most likely much more advanced than
we are, because we've just appeared a very short
while ago, so I presume that what ever they may've
evolved into is much more adaptable.
Anyway, I can't vote on the numbers you posted...
Live long and prosper.
Nope, a horse is approximately a particle. If we use a sphere, we have to consider the horse to have VOLUME. Which is of course nonsense, isn't it?To a physicist, a horse is approximately a sphere. I didn't think that orders of magnitude would be a problem.

I think 1, as IMHO by intelligent life we really mean life that is like us. And I don't think any alien "lifeform" in this galaxy would have a chance in hell of being like us enough for us to consider them intelligent.

As we think of it, yes. Perhaps some equivalent would exist, but then again would maths really be a judge of intelligence? Computers know maths, but we judge them not to be really intelligent...Interesting. You feel that mathematics, as we think of it, could be a unique phenomenon?
I think you'd have some problems there if you everOriginally posted by Ivan Seeking
Besides, 10^4 is about 10^6 as compared to 10^10
