The significance, if any, of these coincidences is not understood. What is understood is that, if these quantities were slightly altered, then no form of complexity or life could exist in the universe.
Speak for yourself. I understand the significance, and so do many others who do not have an atheist water bucket to carry.
"Slightly" is a grotesque understatement. There are at least 40 such constants and to point out the precision of just ONE of them, gravity is precise within 1 part in 10 to the 10 to the 123rd power, according to one cosmologist.
1 in 10 to the 50th is impossible.
If you think this principle means that the Earth is the only planet, out of trillions, with life, you're even dumber than you first appeared.
What a convincing argument THAT is. No, really.
