Undergrad Could fundamental laws change in Dirac's Large Numbers Hypothesis?

Click For Summary
SUMMARY

Paul Dirac's Large Numbers Hypothesis posits that the fundamental laws of physics may evolve over time, suggesting a dynamic nature to these laws rather than a static existence. The discussion raises critical questions about whether fundamental constants would also change and if there exists a hierarchy of laws governing these changes. It emphasizes that if such changes occur, they must be mathematically describable, leading to the speculation of an ultimate, unchanging set of laws. This hypothesis challenges the conventional understanding of physics and invites further exploration into the nature of fundamental laws.

TL;DR
Could fundamental laws change in Dirac's Large Numbers Hypothesis?
Paul Dirac proposed a hypothesis called "Large Numbers Hypothesis" (https://en.wikipedia.org/wiki/Dirac_large_numbers_hypothesis), where he basically stated that, if he was correct, laws of physics would change with time.

But what about fundamental laws and constants? (Not only 'effective' laws)? Would they change?

Also, according to this hypothesis, if laws would change, then there would be more fundamental laws dictating how they change.

But, if this hypothesis was correct, would there be the possibility that eventually these more fundamental laws would also change? Did Dirac consider this possibility?
 
Space news on Phys.org
The fundamental assumption here is that if the laws of physics change, then they do so in a manner that is describable in a mathematical way. That mathematical description would be part of the more fundamental laws. Presumably there would be an end to the recursion at some point, where there is a final description that doesn't change at all.
 
I always thought it was odd that we know dark energy expands our universe, and that we know it has been increasing over time, yet no one ever expressed a "true" size of the universe (not "observable" universe, the ENTIRE universe) by just reversing the process of expansion based on our understanding of its rate through history, to the point where everything would've been in an extremely small region. The more I've looked into it recently, I've come to find that it is due to that "inflation"...
