# Evolution principle of the physical laws

I wanted to know if there is a physical theory that considers that the laws of physics undergo an evolutionary process. That see the law of physics or the absence of them, as something dynamic, and that with time they slowly converge to something we know today. A kind of simulated annealing of the physical laws.

Hi Aron. Welcome to Physics.SE. Please don't add user signatures below your posts. Most of your info is provided by your about me and your own user card ;-) –  Waffle's Crazy Peanut May 5 '13 at 8:04
You might want to check out Lee Smolin's "Life of the Cosmos", it's a bit outdated but nevertheless very interesting!! –  Schlomo Steinbergerstein Jun 5 '13 at 7:34

Yes, evolution has influenced physics, though it isn't wide-spread. Cosmologoical natural selection draws upon Darwin's natural selection. It postulates that a black hole, upon collapse, spawns a new Universe, with parameters similar to its Universe, though slightly mutated. By this, it is meant that the fundamental parameters in the parent Universe are $p=(h,e,c,G,\ldots)$ and in the child Universe $p\prime=(h+\delta h,e+\delta e,c+\delta c,G+\delta G,\ldots)$.

Consequently, stable Universes which permit black holes survive and proliferate, whilst those that don't perish. The population of Universes ought to be dominated by those that have the best conditions for black holes.

In string theory, there is the so-called string landscape of $\sim10^{500}$ vacua, which preserve or break different symmetries, and result in different laws of nature. I'm not sure an analogy with evolution is appropriate, so I'll leave it to an expert.

Also, I'm sure that there physical systems that exhibit emergent complexity (rather than evolutionary features per se). For example, complicated features of special relativity, like time dilations, contractions, planes of simultaneity etc, emerge from two simple assumptions.

Interesting but here we small variations of physical constants, obviously with huge implications. But what I meant, is more something like that initially no physical laws at all, all behavior is possible.Then slowly with time, we start to observe patterns of behaviors (embryonic physical laws). Something similar of embryonic human societies, where initially there are no laws, no precise social conducts but with time, only the bahaviors that permit survival of the entity persist. –  Aron Wahl May 5 '13 at 9:15
any references to the creation of universes? I believe, multiverse theory is still in it's infancy and not yet proved/disproved conclusively. –  Vineet Menon May 5 '13 at 13:16
@vineetmenon I've read about it in a popular cosmology book, I can't remember which one. Lee Smolin proposed it in his book The Life of the Cosmos (which I haven't read). I certainly agree that Smolin's idea hasn't caught on much, and that many don't recognize it as science in the Karl Popper sense. –  innisfree May 5 '13 at 20:04
Many phyicists disagree with Lee Smolin about these ideas, but this answer is somehow interesting. –  Dilaton Jun 5 '13 at 11:26

The reason why the "evolution of physical laws" is not popular is because we can make sense of observations from a long time in the past with the laws we know (star formation and evolution comes to mind). One can of course consider an change in physics with time, but this would only add complications to a thoery that was perfectly able to explain most observations when it was static and therefore fall victim to Occam's razor.
