We have no reason the believe otherwise.

My belief is that they do not. However, there are many special cases where established and accepted theories/laws are proven inadequate.

This really hits at the heart of Special and General Relativity and why Einstein wanted to call it the "Theory of Invariance." I could go on at length because I used to teach Special and General Relativity and love the topics. One could say that the Einstein's entire opus was built upon absolutism and that he dreaded the term "Theory of Relativity." Do a google search on "Theory of Invariance + Einstein" and see what people much smarter than me have written about it.

Aren't most of those cases 'incapable of predicting', versus 'contradictory results'? Plank scale / uncertainty / divide by zero kinds of issues?

as einstein put it - god isn't playing dice. 1. universe is running under definite laws. 2. we know them in part. it is our limitation not of laws. 3. they seem to change only when our understanding changes (maybe improves). 4. there is no variation in laws is in iteself a proof.

See the problem with this statement is that although it is attempting to effect a Scottish accent it is in fact written using the rules of a non-rhotic accent which the majority of the English speaking world does not use, including Scotland. ;P Just thought you'd like to know. :-D

1. The laws of physics are the same, everywhere in the universe If you have an apple falling from a tree, you would be able to calculate the time it reaches earth by using Newton's famous equation. However, if the tree is sank under the water the equation would seem wrong. That's because we didn't considered all the other forces present, or, the equation was not complex enough (e.g. for the case we need to consider the relativistic effects). Generally, there is always a broader context that covers all facts, so you will be able to precisely calculate the apple falling under the water. The statement "The laws of physics are the same, everywhere in the universe." would be equivalent to "All that is, is what it is", which would be true. 2. The laws of physics do not change This is acctually the same question as the first. ...so they both are true :)

Of course the laws of Physics vary - ask any politian! Actually 'laws’ is sort of a misnomer, they are not laws, they are actually observations/interpretations made on how things interact. Once you look at them from that perspective there should be no surprises if they do alter or that we have got it completely wrong. After all Newtonian physics once explained most things .... (except for the price of apples). Even if we do get to a unified theory of everything, how can we be sure that it’s only another view point! Even with a proven unified theory, it still begs the ultimate question how did these laws come to be, probably a question that can never be answered. Even those in the Religious domain come up against similar theological problems, except they can leave it to their chosen God to ponder such questions!

But the beer is flat. Not to mention the women.
The laws can change, our perception (and interpretation) of them can change, the world can change, but the actual physics stay the same. There may be laws that need amending or as yet haven't been written as in all legal matters.
The tragedy of your times is that you may get exactly what you want!

Newtonian and Maxwellian mechanics don't work so well on small particles, like electrons. Quantum Mechanics doesn't work so well in the macro world we perceive with our senses. Heisenberg's uncertainty principle works well with small particles like electrons, but has no meaning when we are talking about a futbol. When you speak of the laws of physics, it usually depends on the size of the universe you are considering. We don't really have a unified theory that explains all things. The holy grail being the unified force theory. So, to answer your question, Newtonian laws apply to a futbol (or baseball), but Quantum physics applies to the atoms that make up the matter in the ball. And nuclear physics will hurt your head. Nuclear physics and Microsoft(R) Vista(R) should be avoided in order to have a nice day.

Good answer. Newtonian mechanics concentrates on the things that most people can see or do everyday. For example, if you play pool or snooker you should use Newtonian mechanics to work out where to hit balls with the cue ball to get them in the pockets. But Newtonian mechanics starts to break down at extremes. For the extremely small, quantum mechanics comes into play. If you start going fast, that's very fast (ie, you travel in a space rocket, not a fast car), start using Einstein's theories of relativity (also used for nuclear bombs, E = mc^2). If you go very big, ie, look at the cosmos - galaxies and the universe, then you start going into other theories, like string theory that models the universe as 11 or more dimensions. So, do the laws of physics change? No. But, they do break down at the extremes and new theories are written, tested, proved or disproved.

And not forgetting things like: Inflation - which requires the speed of light to have been very much higher during the very early universe (within about 10E-12s of the big bang), or for general relativity to have not held then.

I just thinks it's all relative... Hee, Hee :-D Actually I try to not be too certain about anything. The only things I have seen that are constant are: 1. Change - everything in this reality changes continually 2. Humans resist change more that anything else - we are the Universal Yang to the Cosmic Ying. Everything else is up for debate. That is not to invite anarchy, but to recognize that existence in this reality is dynamic, always in flux and that balance & harmony are moving targets. They have to be, because lack of any movement or flux is stagnation; stagnation is lifeless.

Easy by definition: In physics, if it changes with the location or over time, it is not a law. :D

I think most physicists would put both of those statements in the category of reasonably well supported assumptions. Astronomical observations of distant objects are the best evidence we have in support of both. If these observations aren't anomalous then it's likely that physical law is homogeneous throughout space-time. That being said there are some important points to keep in mind about observations of distant objects: 1) they are actually observations of the past. 2) they are necessarily more limited then observations made in local space-time.
