Philosophy of Everything

Many physicists observe that Universe seems to be carefully crafted to sustain life. Only slight changes to physical laws constants would make life as we know it impossible. However, I think this is more like a case of selection bias. We observe these physical constants because we happen to live a type of life that is possible in this observable Universe. Thought experiment Let's imagine there are 4 Universes. I don't find too many arguments for the multiverse hypothesis, but let's imagine them for the sake of argument. First Universe is similar to our own Universe, it can sustain a type of life based on Carbon matter combined with various other atoms The second Universe has slightly different physical constants that makes Carbon links unstable. Still, life is still possible based on Silicon, including some humanoid intelligent beings  The third Universe is way different, it consists mostly on anti-matter. However, intelligent life can develop based on Carbon anti-matter Th...

Biological life is somehow very probable on Earth. Even when many species have been extinct, other species emerged, unexpectedly similar, however different. Many of them had backbones, one mouth, two eyes, nails. It is like... life is bound to exist only reusing similar patterns, at least in this time frame.  Once the Earth was too hot to sustain life. Someday it will again be too hot or too cold for life. But for now all is ok, Earth seems to have the right balance of atoms in the air and in the soil to make the life probable, you only need a seed. We can imagine that these conditions are very special. Would it life be possible in rather different conditions, even if the temperature allows and you manage to have water, oxygen, carbon, hydrogen?  Would it still be probable to live rather than die if other minerals that we use today would be more scarce? Would life still work if some minerals would become way more abundant? Would DNA create the same organisms we know when for...

"Believe" is often associated with religion. However, even for using the " scientific method ", we are forced to assume certain qualities of the Universe that we cannot prove nor fully verify. The most basic assumption is that there are common laws that are universal and they function the same across the whole Universe. This is a leap of faith that we have to take if we believe that the Universe can be understood at all by humans.
