Yer cannae change the laws of physics, Jim!

Back in the days when I went to school, when the world was black and white and young ragamuffins spent their days acquiring soot stains from their travels up and down chimneys, I was taught the following: 1) The laws of physics are the same, everywhere in the universe 2) The laws of physics do not change Does anyone have any proof of either of these statements or are they assumptions? Rich
These are assumptions made in order to allow physics to proceed. Otherwise if the laws of physics were different in different places then abservations we make of things such as the motion of stars and of light become meaningless. It's essentially wishful thinking based on gut feelings backed by reasonable common sense. However recent work has shown that things such as the speed of light may actually have changed over time, leading the possibility that the laws may change over time, may be different in different places, or may simply be beyond what we can currently grasp. Physics is phrustrating.

Well history shows that the laws of physics change as time goes by. I'm confident alot of our physics laws that have been said to be absolute will be proven wrong eventually. After all if we knew everything about physics already we would not still be stuck on this planet.

No politicians means no political structure. This means no organized society which is called anarchy. I don't believe anarchy is the solution to war.

Doesn't the "Law" part complete the idea? If I remember right Law is higher order than theory and such... been a while though and the physics I enjoy most... well... Law sums it up I think.

Maybe in this universe, but in the next one over, gasoline is free, there are no politicians, and hence there is no war. :)

There are many astronomical observations that agree with those statements. Things like spectra of stars, observed motion of stars within a galaxy and many other observations point to that being true. Those are only observations not experiments The vast majority of all experiments have been done at the surface of the Earth, and the most distant experiments from Earth have all been done with unmanned probes, and all of them within our tiny solar system. The current set of laws for describing the universe has gone from a hand crafted assembly or C++ application to the bloated enterprisy conglomeration of VB modules that is the standard model. Everyone wants there to be something simpler, nobody knows what it is, but perhaps finding it has to do with questioning assumptions like those.

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.

well, this is true. think of it this way: the universe works the way it does and it's true everywhere the universe works. but the real question is, do we know the law of physics? you can tell it an other way: the law of mathematic don't change. but does our description of the universe is mathematically accurate?

this a communication problem. maybe the speed of light change, mybe this or that change. but the law of physics don't! it's just what we know of them which does!

These are simplifying assumptions - an application of Occam's Razor. However, any phycisist worth his salt would love to find that the laws of physics change over very large distances or over large time scales. Physics would become difficult, scarey but VERY interesting. Would this be any different than giving the kiss of life to Schrodinger's cat?

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.

I'll be ..... I just threw out my physics, astronomy and cosmology library and bought a bunch of bibles! And everyone: the Universe was not created by the Big Bing. It took just 7 days for everything to be created and all started on 23rd October 4004BC. I wonder if they had all necessary development permits!

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 :)
