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.
