The fact that space/time interval between two points joining a ray of light is always zero - does not prove that the universe does not exist. It simply says that just as in Maths you have concept of zero which we understand - accept and use as a tool without any difficulty. So too in Physics we also have a 'zero' appearing in space/time (the difference being --this zero comes in four dimensions). But Light has another unusual quality - the fact that the speed measured in any reference frame is always same has serious implications which I think can translate to the idea that light does not have a mere objective reality but also has intrinsic subjective element hence any frame will still measure the speed of the same beam of light as being exactly same no matter how fast the observer is moving towards or away from the light beam. --- That is intriguing and has metaphysical overtones! jay Quote Link to comment Share on other sites More sharing options...
Guest guest Posted July 21, 1999 Report Share Posted July 21, 1999 Too scientific to be grasped by an accountant! May be, Dr. C.S. Shah can do it. Thanks, Jay!

Guest guest Posted July 22, 1999 Report Share Posted July 22, 1999 Dear jay i think i will hae to go physics books again to have a look in to special relativity n general relativity . But after reading ur comments i felt the existence of zero in mathematics is really something. 0 representing the null or the unexistent. It seems quite philosphical. Once i was trying to figure out the reality of negative numbers. I stopped after thinking that negative numbers do exist but there existence is relative to positive numbers.
