Why Does the Universe Exist?

To start, we’ll begin with absolutely nothing, not even the existence of laws of physics. Therefore, we will first consider the genesis of physical laws. Accordingly, consider the proposition:

“There are no laws or rules”

1. If there are no rules, then every arbitrary rule must exist. Otherwise, we would then have to have rules precluding one or more rules. That would contradict the proposition that there are no rules.

2. Some of those infinite possibilities of rules, like quantum physics, would “break out” artifacts such as our universe because that is implicit in them. If they didn’t, then they would be implicitly precluded and we’re back to the first point.

3. One of those rules, perhaps quantum physics laws, may be unstable to having absolutely nothing and so our particular universe or multiverse is spontaneously created.

In summary, something exists from nothing because “no rules” requires all rules and some of those rules require the existence of complex artifacts like our universe.

Of course, all the above is metaphysics, not to be taken seriously, but it’s fun to speculate.

PS.
The above was inspired by Anselm of Canterbury’s so-called ‘proof of the existence of god’ whereby ‘existence’ is implicit in the definition of a greatest god because a god who exists is superior to a god that did not exist.
