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?

The answer depends on your world view: a) Materialism, i.e. there is no God: No, your 1) and 2) cannot be proven, they are considered constant only because our observations and experiments agree with them being constant (currently and viewed from earth), however, there is no logical reason why this invariance should continue in the future. b) Christian Theism, i.e. there is a God and He intended for people to live on earth and to be able to figure out that we are here for a purpose. Yes, your 1) and 2) can at least be assumed, because the laws of physics are extremely finely tuned to allow life to exist ( http://www.leaderu.com/science/ross-justright.html ), and being tuned by God makes it logical that they stay the way they are, i.e. something that was carefully built stays the way it is. It would only change if the builder makes revisions.

They are not assumptions. 1. The proof that the laws of physics are the same everywhere in the universe is Einstein's General Theory of Relativity which lays out the structure of the universe required to make the laws of physics the same in all frames of reference. The things that most people associate with the Theory of Relativity, E=mc^2, space-time, time dialation, etc. are the results of the structure that Einstein proposed and have been tested and verified. The General Theory of Relativity was the result of Einsteins reconciliation of Maxwell's equations, which do not allow for a standing electromagnetic wave, and Newtonian physics which held that space and time were seperate static entities. Prior to Einstein's General Theory of Relativity, there was a Theory of Relativity for Newtonian physics which held that the laws of physics were the same in all frames of reference but was primarily concerned with mechanical physics. 2.Our understanding of the laws of physics has changed over time but no one has ever demonstrated that the laws of physics themselves have changed. This is a good thing as relatively small changes to the laws of physics or some constants could radically alter the universe say making atomic structures or fusion impossible. As a for instance, to change the speed of light you would have to change the permitivity of free space which would in turn affect the electromagnetic forces between nuclear particles which could in turn change the energy released by fusion. If this change were to occur depending on which way it changed, some stars would either collapse into black holes or explode as the balance between the pressure from fusion and the weight of the matter in the star changed. If the laws of physics did change it is likely we would never know about it as we would almost certainly be instantly anihilated.

I knew someone would respond with an intelligent comment like this! News flash: Not every Christian has the Medieval, anti-science mindset that you're describing (though, sadly, too many do!)... On the contrary, some of us actually have enough smarts to understand that if God created the Universe then the Universe must reflect this fact. And if the Bible really is the inspired Word of God, then science and the Bible must line up. The anti-Big Bang and 7-day-creation theology comes from a gross misinterpretation of the creation account in Genesis. The word for "day" there is "yom" (as in Yom Kippur, etc.), and, while sometimes indicating a 24-hour period, can also mean "eon" or "era". We have this usage of "day" in the English language as well, as in "back in my day" or "the day of the dinosaur"... So, yes, the Big Bang did occur, and many billions of years ago. For something to be created, it has to have a beginning (as in the Big Bang), and this in turn indicates a cause. The Bible tells us that God said, "Let there be light", and the light has been penetrating the darkness ever since. Amazing that Moses (who penned Genesis) could know about the Big Bang and the continuing expansion of the Universe so many thousands of years before the science of cosmology began! The reference I cited is from an organization called "Reasons to Believe" that believes in the 100% validity of the Bible and the 100% validity of science. You should check them out: http://www.reasons.org/[^] P.S. To paraphrase Sagan: Think of how many scientists attempt to validate themselves with only science that they can personally comprehend. Sagan was great at marveling over the graspable Universe around him, but didn't try too much to ponder what's beyond this. The Big Bang proves that there is a transcendent realm (doesn't it?). Einstein, in his later years, brought embarrassment to his scientific career, the most distinguished in history, by rejecting quantum physics, essentially because he couldn't personally grasp it... Love both these guys, and how human of us all to need to define all of reality according to our own tiny little contexts...

Your assertions presume that "The laws of physics" includes a complete description of the entire how the universe world. By Godel's incompleteness theorem, this is not possible. QED. Cheer, Will.

Any organized decision-making process inclusive of more than one person negates the state of pure anarchy which, like a pure vaccum, is a state never to be seen in nature beyond a very local point of view.

But... "with God all things are possible" so He could change things around on a whim. The Earth may once have been flat. The Sun may have revolved around the Earth. Dinosaur fossils may have been planted. You just can't trust someone like that. :-D

Our current understanding of the universe only works if these laws stay the same. But even then i'm pretty sure the physicists bend the laws quite a bit to explain alot of strange stuff.

gasoline wouldnt be there but there would be something equivalent which caused the war. People have been fighting for materialistic things all over the history.

Well, it's still a theorem rather than a law - suggesting it isn't proven. If it is correct then it may be that a theory of everything can never be produced. But does this have a bearing on the original question? It was not so much one of our ability to describe everything but rather, is it provable that the evrything has always been and will always remain the same everywhere. Cheers, Rich

If the law changes, then we had it wrong to begin with, and thus it is only our understanding of the law that changes. If it is not the same everywhere, regardless of space or time then its not an absolute law. The whole point of a having a law of physics is for the purpose you mentioned, it is the same everywhere, regardless of time or space, and it does not change, ever. if this can not hold true then there are simply no laws! (this is not equivalent to anarchy though) It is our understanding that changes, not the truth itself. That being said our documented understanding is not correct, take the 2nd law of thermo dynamics, the first qualifing phrases "in a closed system" and "in equilibrium" these are 2 conditions that have never been proven to exist so whats the point? you cannot achieve equilibrium, because you can not close any system from the rest of the universe, just as you cannot reach absolute zero. only a perfect vacuum at absolute zero would satisfy these conditions and no such thing has ever been observed, nor has anyone thought that we could observe such a thing. The statements above: 1) The laws of physics are the same, everywhere in the universe 2) The laws of physics do not change are actually definitions of the term 'law of physics' and it is true because we say it is, that is what a 'definition' is. But what we say the actual laws are, well thats just clever guess work.

Yes, Rich, I have proof of both of those statements. I assume that you would now like to "see" or "hear" the proof? Okay, then please send 5$ and a self addressed stamped envelope to...... :-) yuk! yuk! yuk!

Read Powers of Ten. The laws of physics are thought to have mutated since the beginning. I don't know if any more mutation is predicted though. It's a bit like trying to imagine infinity or more than 3 dimensions (apparently infinity exists and there are 11 dimensions in our universe). At what point in time/space does 1 + 1 = 433? Or does it ever? And at that point, would we realize the laws had changed? What if time stood still? We wouldn't really know it would we? I'm going to go take my thorazine now.
