Fine tuning of the universe
Just the pure math is mind boggling. So the main constants we know are gravity and If we increased the strength of gravity by just 1 part in 10^34 of the range of force strengths (the equivalent of moving less than one inch on the universe-long ruler), the universe couldn’t have life sustaining planets. If strong and weak nuclear force or electromagnetism were to even change slightly there would be no bonds and no matter. Cosmological constant (which controls the expansion speed of the universe). is 1 part in 10^120. And based on the fine tuning In The [i]Road to Reality[/i], physicist Roger Penrose estimates that the odds of the initial low entropy state of our universe occurring by chance alone are on the order of 1 in 10^10^123.
