Infinite Universes or One Universe?
Things in our universe are just perfect. Everything seems to neatly “tie-in” and work well. It has this structure that is conducive to life. If things were different, no life could have been possible. For example:
Consider just two possible changes. Atoms consist of protons, neutrons, and electrons. If those protons were just 0.2 percent more massive than they actually are, they would be unstable and would decay into simpler particles. Atoms wouldn’t exist; neither would we. If gravity were slightly more powerful, the consequences would be nearly as grave. A beefed-up gravitational force would compress stars more tightly, making them smaller, hotter, and denser. Rather than surviving for billions of years, stars would burn through their fuel in a few million years, sputtering out long before life had a chance to evolve. There are many such examples of the universe’s life-friendly properties—so many, in fact, that physicists can’t dismiss them all as mere accidents.
So what does this mean? How come there is such an amazing set of coincidences in the ONLY Universe out there! And “coincidence” is something that the scientists dont like! So what could the possibilities be?
1. A Benevolent Creator
2. More than one (in fact infinitely more!) Universes or Multi-verses
And the latter may be the ONLY non-religious explanation for the apparent “fine-tuning” issue which means that the laws of universe seem custom-tailored for emergence of life.
“For me the reality of many universes is a logical possibility,” Linde says. “You might say, ‘Maybe this is some mysterious coincidence. Maybe God created the universe for our benefit.’ Well, I don’t know about God, but the universe itself might reproduce itself eternally in all its possible manifestations.”
