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

In summary, Paul Dirac proposed the "Large Numbers Hypothesis" which suggests that the laws of physics may change with time. This would also include fundamental laws and constants, and would be governed by even more fundamental laws. However, it is assumed that there would eventually be a final description that remains unchanged.

TL;DR Summary
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?

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.
 

1. What is Dirac's Large Numbers Hypothesis?

Dirac's Large Numbers Hypothesis is a theory proposed by physicist Paul Dirac in the 1930s, which suggests that the fundamental physical constants of the universe, such as the gravitational constant and the speed of light, may not be truly constant but instead vary over time.

2. What evidence supports the Large Numbers Hypothesis?

There is currently no conclusive evidence to support Dirac's Large Numbers Hypothesis. Some scientists have proposed that certain astronomical observations, such as the apparent variability of the fine structure constant, could be explained by the hypothesis. However, these observations are still open to interpretation and do not definitively prove the hypothesis.

3. Could the Large Numbers Hypothesis change our understanding of the universe?

If the Large Numbers Hypothesis were to be proven true, it would challenge our current understanding of the universe and the laws that govern it. It could potentially lead to new theories and explanations for phenomena that are currently unexplained.

4. What are the potential implications of the Large Numbers Hypothesis?

If the Large Numbers Hypothesis were to be proven true, it would have significant implications for our understanding of the universe and could potentially change the way we approach scientific research. It could also have practical applications in fields such as cosmology and astrophysics.

5. How can we test the validity of the Large Numbers Hypothesis?

Scientists are currently working on various experiments and observations to test the validity of the Large Numbers Hypothesis. These include studying the behavior of physical constants over time and analyzing astronomical data for any patterns that could support the hypothesis. However, further research and evidence are needed before any conclusions can be drawn.
