All models, Models, Theories, and Laws in science
are subject to change and are always
accountable to Nature and experimental confirmation
“Nature cannot be fooled” -- Richard Feynman

In science if you have two models that make the same predictions,
the simplest one with the fewest assumptions “wins” --
this idea is known as Occam’s Razor
