Newer observations suggest 200 billion with an average of 100 million stars per galaxy and 3-10 planets per star. 60,000,000,000,000,000,000 planets on the low end? Yeesh.
- mr_mitm 4y agoSo what? 40 zeros after the decimal point should make you go "Yeesh" even harder.
- mcbutterbunz 4y agoIt honestly did after I thought about it more.
- ako 4y agoFor some perspective 70b sandgrains in one cubic meter sand… so they found 100x3x6 cubes of sandgrains…
- superposeur 4y agoYes these are huge numbers, but quantities associated with physical space (# of objects) are nothing compared with quantities in combinatorial spaces (# of possible 256 bit passwords or # of possible games of chess). It seems plausible that getting the sustained chain reaction of life going in a soup of organic molecules and not immediately interrupting it may be at least as unlikely as randomly guessing a 256 bit password, in which case it will certainly never have happened a second time in the volume of space time we call the “observable universe”.
