I came up with an idea more than a year ago, but I've yet to take a physics course, still in high school, but please bear with me. Take the Kaluza-Klein approach that light originates from the 5th spatial dimension, at the nearly unreachable Planck length. Now, light is supposedly a vibration that originates from there. If the light traveled parallel to our 4 dimensions of space-time, then we would never see it, confined to the 5th dimension. But it doesn't and crosses our dimensions. That's where you can bring back the concept of absolute space and time. Since the entire universe may be moving at an immeasurable rate, because we all have mass, but it isn't measurable without some known constant, because everything in the universe is moving together at that speed in addition to any expansion or any other movement. But take the light beam. Since it crosses our dimensions from the 5th, all matter we know may be moving through the universe at a certain rate. But light isn't confined to our dimensions, moving through the 5th dimension as well, but it is not affected by the motion of the matter through space-time. As best as I can illustrate it, imagine our space-time by a line, and the light beam crosses our dimensions from some other point. The point of intersection can be a reference for absolute motion, space or time. Then suppose that time is a spatial dimension, that we are moving through. The reference point, to determine our velocity is the point of intersection of the light beam. Suppose that we are the ones that are traveling through space-time at 300,000 km/sec, away from the beam of light. Since we are moving through the universe together with everything else, except for light, we can just as well be moving from the light beam at the observed rate that it moves away from us. Relativity says that as we move faster, time slows down for us. Now, time, as a "different" represents change as well as space. Now if we have a particle, and its velocity increases, the change that occurs is the particle begins to approach the point of intersection of the light beam and space-time. As it approaches the speed of light that we observe, which in this case is the speed that we are moving away from the light, its change in time decreases, and at the point that it reaches 300,000 km/sec, the velocity of light, time comes to a stop because the particle has ceased to change or move through time. Take e=mc^2 If e is the total energy of the particle that encompasses the difference between c^2 and e, that gives the true mass to be 1/m, a hyperbolic function of absolute energy vs. mass. When the difference in energy approaches 0, then mass becomes infinite. I can barely continue anymore because I can barely keep up with my thoughts. I'm as confused myself as many of you might be right now, so I'll get back to this in a little while. Again, I'm only 15 and have yet to take a formal course in physics, but any comments would be appreciated. I posted this a while back in the old forum with little replies. Hopefully I can get some more help this time around.
