Constants are almost ALWAYS global. Seriously, do you even do programming? You talk about programming like you are an expert at it, but when you actually say things, it's just wrong. In C, C++, Java, and even PHP it is VERY common to declare "bitflags" as global constants. This is done in thousands of programs, in fact, any C/C++ program that is more than "return 0" includes constants whether the programmer knows it or not. In C/C++ as soon as you include any of the standard header files you are adding constants to your program. So if every C/C++ program in existence uses constants, in a global scope why would you say it is rare? In fact, up until a change in the C standard, constants were REQUIRED to be global, there was no way to make a constant that wasn't global.

Oh and btw about your 'absolute zero' stuff, how about you stop stating unproven theory as fact? For every statement you stated in that little message of yours, I can give you 2-3 credible refutations by other competing theories. And some of what you said is just wrong, xrays are the fastest EM? Not even close, Gamma rays are far faster. And btw you quote the speed of the universe, well stating that the universe has a speed suggests that the universe is moving. This indicates one of two things. Either a.) you mean it is moving with respect to a CONSTANT body of reference, or b.) it is expanding by laws defined by Hubble's CONSTANT. And the universe collapsing? Ever heard of Friedmann's three models of the universe? Well they follow logically from the fact that the General Theory of Relativity predicts that there is no cosmological constant. It predicts three possible universes, either a closed universe that will contract and implode with a "big crunch", a universe that grows asymptotically close to the point of collapse, or a universe that grows infinitely. First off just general statistics show that there is only a 33% chance the universe will contract, and in recent years with newer theories the universe is viewed to be a "saddle" which is predicted by the model of the universe suggesting infinite expansion.

There is a difference between fact and opinion, your commentary on absolute zero (and constants in general) seems to neglect that issue.
