The Laws of Physics: Fundamentals or Variations?

[geordief]

are they fundamental (like the atom was considered to be)?
Or might they vary from one region to another??
Might there be an infinite amount of regions with an infinite amount of laws?
Does a similar possibility hold for universal constants?

 

[russ_watters]

As far as we can tell, they are universal.

 

[geordief]

would there ever be any conceivable way of finding out ? is that just a ridiculous question?

It's a fundamental principle of science that you can never do every possible experiment in every possible place at every possible time, so you can never know anything absolutely for sure. But you can know to 99.9999999999999999999999% (however many 9's you want) certainty and that'll just have to be close enough.
