A question then, for the scientists among us (caution, paradoxes abound):
Are the “laws of physics” truly unbreakable? If so, are the laws of physics that govern our universe the same laws of physics that govern all the alternate universes? In an alternate universe, can F <> MA? Can E <> mc^2? If the laws of physics (and the two I sited are among the most universally accepted and undisputed ones) are truly unbreakable, then how can it be said that “anything is possible”? Then, only things that don’t violate the laws of physics are possible, and a whole lot of things (most things, in fact) are impossible.
Isn’t the term “laws of physics” a lofty title, and aren’t they really human hypotheses that have graduated to be called laws (because no counter-example has ever been found, despite significant effort to do so), but are not really laws at all? Because otherwise, if they are really “laws” then they are akin to the 10 Commandments, which, according to the Old Testament, were given to Moses by God Himself on the top of Mount Sinai (where I myself have stood but that’s another thread), and are not dependent on human experience or experimentation.
What happens if it turns out that a law of physics DOES have exceptions? Does it get demoted back to an hypothesis – and a discredited one at that? How can we say that the current laws are impervious to such treatment?
I submit that the current “laws of physics” as they are now understood are fully susceptible to not only being broken, but are vulnerable to future discreditation and demotion.
Laws of physics are unbreakable, because we have not found a way to break them. The phrase 'Law of Physics' is a human term to refer to these rules that are seemingly embedded into the way the universe works.
I can't remember for sure, but I don't think laws that hold in our universe are required to hold in other universes because a set of variables called the 'physical constants' can be different. At the very least, the laws are still true but will create different effects.
The phrase "anything is possible" when used with regard to infinite universes / mulitple universes is taken mean anything with a non-zero probability. So not absolutely anything. E.g. An event in which E<>mc^2 (e.g. two particles collide, 4 particles worth of energy is created) has a 0% chance of occurring, so would not come under the term 'anything' in this case.
So yes, many events cannot happen. But everything discussed in this thread, like the origin of the universe, emergence of lifeforms, the structure of our world: all of it is physically possible, so the arguments still hold in this case.
Yes, Laws are just theories (not hypotheses as you say though, check the definitions!) that we have decided to call Laws. It is extremely likely that some of them are not actually Laws (but they will be almost laws i.e. nearly always right). Most of them we are pretty damn sure about though, so really there isn't any reason to doubt the whole scientific world because of this. Predictions the current laws of science make are nearly always true. Predictions made using religious theories are nearly always false, in contrast.
Physical Laws are not akin to commandments at all. A Law is something you cannot break under any circumstances because it is impossible to do so. I can break the commandments if I wish to, therefore they are only rules. Reality itself does not stop me from stealing things. It does stop me running through walls. One is a rule, the other is a physical law.
So yes, a couple of physical laws will be shown to have problems in the future, and in fact many of them have been already. But they are not wrong. They are incomplete. You are very confident that these theories will be overturned in the future and thus can be ignored now. But what will happen is that the theories will just be redone with a new name and a few extra features to correct past mistakes, because for the most part they are already correct.
That is to say: all the original stuff that we already know is true, will remain in future theories. There isn't a 'right and wrong', just an extent to which everything is explained. So far we haven't explained everything, so our body of theoretical knowledge will expand. But most of what we have already is solid (theory of the gravity isn't going away any time soon, but the theory of quantum gravity which includes the old theory gravity will probably replace it. This is an example of what I mean in this and the previous paragraph).
I hope this answers all your questions!
