At best, it might be classed as a variable used to describe movement in the universe. Without time, all states of the universe would exist. That is not evident. If you don't want to call time 'a dimension' what other name might you suggest? from: Spirit of Truth (using June's e-mail to communicate to you)! Henri Wilson.

Here is a link for you that should be well within your grasp. http://math.ucr.edu/home/baez/physic...R/gravity.html http://alcor.concordia.ca/~vpetkov/gravity.html But please... go on to s.p.r and tell everybody that there are gravitational forces in GR . Why? Its you that has a pathological need to convince someone of something. The term "gravitational force" is a precisely defined term in general relativity. Just like "Coriolis force" is a precisely defined term in Newtonian mechanics. Prove that there are no Coriolis forces in Newtonian mechanics. |

"Robert Calvert" wrote in message ...
While of course your contention that SR is 'wrong' is itself quite wrong (if it weren't, we wouldn't have made it to the moon, or have DirecTV, or planetary probes, etc.). Why do we have to assume that only Einstein's version of Relativity would be required for this? If you mean Einstein's interpretation, we don't. However, the observable implications of SR (at least at scales above the quantum realm) are correct, so we need some theory that is identical to SR in terms of experimental predictions. We might as well call such a theory relativity, since non-observable factors (such as philosophical interpretations) are not scientific attributes of a theory. However, I will fault Einstein and other scientists for one important thing that has led to much confusion. Perhaps they didn't have the proper foundation to state it any other way (in fact, most scientists would still do it this way), Could this mean that most scientists don't really understand SR themselves? If you mean the interpretation, then yes, I believe most scientists haven't really given proper thought to the implications of SR. However, again in the end all that really matters is that the math works -- it describes what we observe. 'Most scientists' are not particuarly concerned with the (presumably) non-scientific aspects of the theories they work with, ie the philosophical implications, metaphysical explanations, and whatnot. They consider that to be either crackpot material, or the egghead musings of philosophers, both of which are irrelevant to most day-to-day work. However, such musings often have an influence on future research, and become relevant later, when new experimental techniques may be available that can differentiate between two interpretations of the same original theory. Then we have two legitimately different theories, and the distinctions suddenly become important. but IMO there is a gravely misleading aspect to the way relativity is usually phrased. Pay attention now: Einstein's formulation of relativity: "There is no preferred inertial frame of reference." The correct formulation: "All inertial frames of reference where the velocity is less than the speed of light, are mathematically equivalent, and there is no a priori reason to prefer one over the other." Any theory that asserts that one twin can return home younger than the other requires a preferred inertial frame of reference. This is why every intelligent person that I know of has a problem with SR. This is where you are dead wrong. The math of SR makes it perfectly comprehensible how two people can go off on different trips (that means with different accelerations, not just symmetrical trips in different directions) and come back having aged differently (btw I made a mistake on this point later, I will correct it here). In other words, given a spacetime history in frame F, we can always transform it to frame F' through some simple trigonometry. For convenience, we usually think of observing the world from whatever frame of reference we happen to be in; but it is perfectly acceptable to use some other frame of reference instead. Sure, we can use any frame of reference we want. But if we want to invoke SR, then we're also forced to declare our preselected frame of reference the privileged frame of reference. No, we're not. We can do the computations in *ANY* frame of reference, and they come out the same. What makes one frame of reference 'priveliged'? As for your 'paradoxes', you don't have it right. If two spaceships do some symmetrical acceleration thing (like fly away fast, then turn around and come back), of course their clocks match perfectly. But this is exactly where the paradox comes into play. Read this again: If we want to extrapolate this experiment to the extreme, we could imagine a scenario in which both clocks have been traveling toward each other at 86% of the speed of light relative to each other for the past 10 billion years and are only recently about to meet. If clock (a) "decelerates" in two seconds to enter the frame of reference of clock (b), should we conclude that clock (a) has lost 5 billion years compared to clock (b)? yes. What if clock (b) "decelerates" in two seconds to enter the frame of reference of clock (a)? Should we now conclude that clock (b) is the clock that has lost 5 billion years? yes. To make a long story short, Who's to say which clock accelerated and which clock didn't? The one that undergoes a huge amount of acceleration (or 'deceleration', they're the same thing) to catch up to the other is the one that loses time (ie its clock goes very slow for a while). The paradox, such as it is, comes when they accelerate or decelerate, and *choose* to view the Universe from their new frame of reference. Among other things, by doing this they may redefine the 'present' moment on the other spaceship to be a year later (or earlier), for instance. Once you comprehend the spacetime geometry transformations of SR, it all makes perfect sense. Only if you presuppose the existence of a privileged frame of reference. wrong. The distortion occurs with you, the observer, at the center; everything else is warped and modified to make your 'present' stay continuous. But the important thing to realize is, none of this implies that your actions have any effect on other observers. They go through their own transformations, and decide that you are shrinking, going slow, etc. and so on. If everyone on both spaceships simply used clocks that were modified to show the 'proper' time of their home planet, they would both see their clocks slow down on the trip out, and speed up on the trip back. In a strictly Newtonian universe, a clock would appear to slow down on the way out and appear to speed up on the way back in so that, by the time one clock reaches the other and decelerates, both clocks will have recorded the same elapsed time. It is true that the twin paradox would be resolved even if we did assume that time is literally slowing down using this formula. But, then again, this is not the Special Relativity that I'm familiar with. (in this example I'm just talking about SR, so the clocks on the spaceships end up synced with the one on the home planet. Note that the twin paradox is really part of GR, not SR, but that's another story.) Correction: the twin paradox is part of SR. My bad. GR simply adds gravity to the picture, which we're not discussing here. Why don't you tell it. I don't know GR well enough to teach it. I'm very comfortable with SR because it is simply trigonometry. Check out this page, it has what I consider to be one of the best explanations of why SR works. http://www.astro.ucla.edu/~wright/relatvty.htm Robert Hope this helps, sty [snipped immature lambasting of Einstein and others] |
