Phu! At last my XRN is working.....! Let me throw a rather large rock in the physical waters, hoping that it will create waves that perhaps can go all the way around the lake and back. I would want to ask all of you this wery simple (?) question: what is time? Let me first try to recap the basic knowledge and ideas in physics today about this subject. First of all, time is not absolute. At least this is what SR and GR states. There is no absolute past and present, or absolute clock ticking somewhere in the heavens. Newton assumed this to be correct, after all muons and other strange beasts did not run around with big signs on them in his time either. But today we safely (?) assume that there is no absolute time. Time is closely related to the curvature of space and thus is a geometrical object. We know that the picture of the slowing of relative time in a strong gravitational well relates to the "dip" in space at the point. (In pictures) Ok, we could rest with these simple explanations, which only describe time as a fundamental part of space, being governed by shapes. But this does not describe (at least not to me) WHAT IS TIME? Why can we say that time is not absolute? Just because it takes on various forms depending on where we measure it? Is it not possible that there does exist an absolute time, a sort of "time-quantum" that can be in perfect harmony with relativity? Is it impossible that time could NOT be continous? After all, we have defined time and the methods of measurement using the "time-meter- stick" prinsiple, and must this not be finite? There is also a limit in our basic knowledge of any system, defined by quantum relations. Please send some of your own ideas, and remember: I KNOW this sounds crazy.....! :-) M&M I asked Him what Time was, He just looked at His watch and asked me to come back tomorrow.
