Possible goldilocks planet (The limitations of science)
Planet postion in a solar system seems to be up to chance. Is Earth lucky or made special? > > "Horner emphasized that the numerous simulations his team ran on Jupiter's influence in the solar system shows that where planets end up is often a result of chance as much as physics. > > "Every object you add to [a planetary] system adds complexity, and the end result is a result of random chances," said Horner. "So if you change something very small when the solar system is forming, it's kind of chaotic.'" > > -Not kind of chaotic, its pretty much a textbook definition of mathematical chaos. Early fluctuations can have long-term consequences for the stability of a system. However, given an end condition and a start condition, we have the tools to be able to reconstruct (most) of the earlier states.- > Read more at: http://phys.org/news/2014-04-mighty-jupiter-earth-habitability.html#jCp-In the case of planets, if there's literally an uncountable number of stars that can have planets, then it is mathematically certain that *somewhere* in the universe there will exist a planet like ours. I don't even flinch at that. I flinch at *any* speculation about life itself. There's a ton of questions to answer. -Consider the evolution of eusociality... we know of 15 species that exist that have ever evolved this trait. (It's the precursor to living in organized societies.) -Using a thought process like that, It might not be unreasonable to posit that life could be rare enough that it only happens in 1 out of every 10 galaxies. (And at those distances... why bother looking?)

\"Why is it, Master, that ascetics fight with ascetics?\"
\"It is, brahmin, because of attachment to views, adherence to views, fixation on views, addiction to views, obsession with views, holding firmly to views that ascetics fight with ascetics.\"
