Your answer is interesting, insightful and educational, for all of which I am grateful. I hadn't considered that perspective and it is all of the adjectives I listed previously.

However, I don't think it answers at least what I meant by the original question, even if it does answer the literal question I asked. That's on me for not using sufficiently specific language. What I meant wasn't "why do things obey the laws of physics as we understand them" or "why do things obey the laws of physics as we've defined them" but more "whatever the laws of physics truly are as defined by the universe, what makes the content of the universe obey them?" I was quite young when I asked my dad the question, so at the time I pictured little Marvin the Martian style physics policemen following atoms around enforcing the law, but I suspect that's not correct.

My question is possibly more philosophical than scientific (or realistically answerable). At that age I was certainly not aware of the simulation hypothesis, which seems like a good starting point, but also raises more questions. Regardless, I appreciate the clearly genuine effort behind your answer as well as the pontification it inspired, at least for me.

An aside: your comment reminded me of the "Maxwell's Demon" Abstruse Goose comic (which sadly I can't find to link here) and this Simpsons bit, which clearly I was able to find to link.

I want to reiterate one last time that people who try to answer questions and educate others are extremely valuable and I meant nothing negative about your comment. Thank you for responding.

Thank you for the kind response!

I was kind of considering that you might have meant the question that way ("why does nature obey whatever underlying law there is"), but as you say, it quickly takes us into philosophical territory.

If I were to give my honest opinion on that as a scientist, I would say that we can never know what the true, underlying guiding principles of the universe are, or even if there are any at all. We can only ever measure the laws of the universe indirectly through observations. This precludes us from ever being 100% certain about the true underlying principles that guide what we're observing, or even if there are any.

As an example, there's a hypothesis (can't recall what it's called) which postulates that the entire universe is in an unstable state. If that hypothesis is correct, the laws of nature as we know them could in fact change abruptly, with the change propagating at the speed of light. This change could amount to stuff like changing fundamental constants, which would pretty much break the universe as we know it.

I'm familiar (very vaguely) with the unstable universe. It reminds me of an author, Douglas Adams I believe, who wrote "There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable.

There is another theory which states that this has already happened."

That's a great quote! I just did some searching: I'm thinking about false vacuum, and can live with the fact that if our universe does decay, it will (according to this theory) happen at the speed of light, so it will be impossible to observe before we are instantly wiped out, which is a calming thought.

This is similar to the thought process cracked.com recommended regarding gamma ray bursts, IIRC.

I'm currently doing some studies and only briefly logged in here to check things, but once my boring studies are done, I'll try to remember to check your link for interesting studies.
