A great subject is also the cosmological constant. Introduced by Einstein, who later claimed it was the biggest blunder of his life, that has returned to make the math work for cosmological observations made in the 90s. As explained by Susskind[1], a sort of negative force that by one measurement is 2.88 x 10^-122 [2] and if it were only slightly different, the universe as we know it would not exist. Add in the "need" for observers in Wheeler's Participatory Anthropic Principle[3], I would say that some extraordinary minds have recognized and proposed some strong anthropic arguments. In any case, the older I get, the more I realize I don't know a damn thing. As a poet once sang: Now, I wish I could write you a melody so plain That could hold you, dear lady, from going insane That could ease you and cool you and cease the pain Of your useless and pointless knowledge [1] https://www.youtube.com/watch?v=2cT4zZIHR3s&fbclid https://www.youtube.com/watch?v=2cT4zZIHR3s&fbclid [2] https://en.wikipedia.org/wiki/Cosmological_constant https://en.wikipedia.org/wiki/Cosmological_constant [3] https://en.wikipedia.org/wiki/John_Archibald_Wheeler https://en.wikipedia.org/wiki/John_Archibald_Wheeler
