Laws of physics from initial conditions?

[Suekdccia]

TL;DR Summary

Are there any models, theories or physicists who propose that the fundamental laws of nature come from the initial conditions?

Are there any models, theories or physicists who propose that the fundamental laws of nature come from the initial conditions? Are there any physicists who propose that the most fundamental laws of physics emerged from initial conditions at the origin of the universe? And according to this view, if the initial conditions had changed could the most fundamental laws of physics have been radically different from the ones we have now?

If you read up on the fine structure constant, you’ll find some discussion on whether it’s value has changed over time or whether it’s value is different on one side of the universe vs the opposite side.

Some physicists speculated on what would our universe be like if the constant were different...

Somethingt that resembles your question a bit is the no-boundary proposal by Hawking.

Brief but inspiring article: I wish I knew more physics.

I would say any of the multiverse models suggest that fundamental constants are different in each universe due to random differences in the initial conditions of each. Steven Weinberg, in an essay in his book “Lake Views” goes on to argue that the expectation for an explanation of fundamental constants will someday be seen as equivalent to to the (ancient) expectation that there must be significance to the ratios of orbital periods in the solar system - and for the same reason - failure to recognize that both are accidents of initial conditions.

Certainly many physicists don’t take this view, but also many do, including prominent ones.

What do you mean by an initial condition? A first event?
