Reflections on The Multiverse


For decades, scientists have always preferred the view that space and time first came into existence fourteen billion years ago in a big bang. The famous picture describes the cosmos transforming from an almost uniform gas of elementary particles up to its current hierarchy of structure which is so complex. Such complexity encompass quarks, galaxy clusters and an evolutionary process governed by universal rules which to the physicists seem so simple. In recent decades though, physicists have discovered something more. They discovered finely tuned features of the universe that seem to go beyond the nature of things.

Physicists and astronomers have discovered what's called "cosmological constants" which are exponentially small when measured and calculated by our most sophisticated equations. The cosmological constants are as they should be so that space won't expand so rapidly that galaxies and stars would never form. Thus, such small value has lead physicists to the multiverse theory. Perhaps we live in an anthropically selected universe. We live in a multitude of universes where the cosmological constants vary from one universe to the next. The bulk of the universes have values that are incompatible with the morphing of galaxies, stars, and planets. The reason why the cosmological constant here in our universe posses the value that it has is because it happens to be one of the rare examples of which the values are just enough to be in a narrow range which is compatible with life.

Some intellectuals consider the multiverse as a reckless abandoning of purpose; that things rarely get right. Owl Man in the movie "Justice League Crisis on Two Earths" makes the claim:


"Every decision we make is meaningless because somewhere on a parallel Earth, we've already made the opposite choice, or nothing, less than nothing. In one Earth, we may be poor. In another Earth, we were never born. In another Earth still, the world ended in nuclear war. And in another... life never evolved."

Recently, more and more data from quantum physics are coming in support of the multiverse theory. Surely, the theory has turned the realm of physics and everything we know about life and the universe into a much more complex and mysterious puzzle. A bulk of the scientists say that it doesn't matter whether we live in a multiverse or not. There's no arguing as to whether life, right and wrong, and the whole of existence is really valuable or not because we have our own universe and Earth. We have our own life and purpose here in our own little place in the cosmos and we should cherish it.

In my opinion, I could care less if there are trillions of universes out there. I may be more than just what I directly see. There may be more atoms and quarks in my body that behave in ways that I can't sense or observe directly. There may be a trillion versions of me out there in the Multiverse. But in the end, all I see is myself and all that other people see in this life is that one version of me. And so in this universe, all those other versions of me disappear and appear only as mirages while I live my life according to its purpose. That if the claim is really true. But for now, it remains only as one of the many possibilities within the realm of physics.

Thus, in contrast to Owl Man, Batman said: "Our first responsibility is to protect our Earth.."

That is a deep sense of thoughts. I never thought about that. Multiverse, indeed a very complex matter to discuss.
