The fact that there is life is as odd as it is exhilarating. It’s strange because the odds of there being a universe fit for life are actually quite small when we consider that if the laws that govern our universe were slightly different, life would be impossible. This means that the configuration of our universe falls within a narrow line of possible options that allow things to be.
For example, if there had been a small variation of only 2% in the setup of the fundamental forces that govern our universe, things would be entirely different. For example if the strong nuclear force (one of the forces that bind the atoms together) had been 2% stronger, all of the hydrogen in the universe would had been consumed in the very early stages of our Universe. The nucleosynthesis (process that created new atomic nuclei from pre-existing nucleons, primarily protons and neutrons), would not have been possible as we know it, thus, other chemical elements such as carbon, nitrogen or oxygen wouldn’t have come into existence. This means, no stars, no planets, nothing would be as we know it.
