The laws of physics ARE part of the universe, even though they arent made of energy or matter, or exist at a time or place.They exist because what they describe exists. The only way they couldn't would be if the things they describe didn't exist, and they do.
For that matter, time and space themselves don't have any of those properties, yet they certainly exist.
Also, numbers do naturally exist in the form of numeric relationships. For example, crystals will always have a certain amount of sides depending on what mineral they are and how they were formed.
Also, at the very start, Arun said stasis doesn't exist. How could you know if it did? Stasis could occur a thousand times a second and you wouldn't realise anything happening.
