The chances of therebeing a water planet like earth?

[Plat]

a. in the milky way
b. virgo cluster
c. known/visible universe

[Pinemarten]

a. 1/100,000,000 give or take 10^50

b. 1/100,000,000 give or take 10^5,000

c. 1/100,000,000 give or take 10^500,000,000

I may be wrong, but my data is improving as we speak.

Hehehehe... Has anyone calculated the probability that a planet formed in a star's "Habitable Zone" will have Hydrogen and Oxygen? Supposedly we know roughly how much of each element there should be and we think we know how planets form... :-?

Platinum Rhymer,

Your posts fall mainly into two categories:

1) Questions that could easily be found by using Google or other search engine.

2) Questions requiring wild speculation, since there is no available hard data.

This question is category #2.

I'll disagree with you on the first one. I'd say the odds of there being an Earth-like planet in the Milky Way galaxy are pretty much 1:1.

:)

Now, the odds that there's another one . . .
