After mulling over special relativity for a while, I have come to some conclusions that seem correct, but I don't know if I'm on the right track. I'd like to know what some of you think. Please keep in mind that I only recently started learning about relativity, so I'm somewhat of a layperson on the subject. I wanted to show that an observation point traveling at the speed of light would contain the entire universe... but how? Special relativity says that if an observer were to travel at the speed of light, the universe would be compressed down to an infinitely thin plane, perpendicular to the vector on which the observer is traveling. Time would stop at the observer, which means this plane would also contain an infinite amount of time (or all of time). Okay, so we have a plane that contains two of the four observable dimensions. What about the other two? If we open ourselves up to extra dimensions (as in superstring theory), the solution becomes simple... I think. From a perspective that includes another dimension, the position of the observer on the plane and it's vector angle have infinite possibilities. If we pay attention to just three of those possibilities, all with the same position but different vector angles, the planes would intersect at a point... the observation point. If traveling at the speed of light can compress two of our dimensions, it seems pretty likely that it can do the same on one of these "extra" dimensions (this is where the "guess" part of my idea came in). The convergence of these possibilities causes our other two observable dimensions to converge onto the observation point as well. If there are 11 dimensions, I suspect that they all have a different effect on each other at the speed of light, but the cumulative effect is a convergence to one infinitely small point that contains the entire universe in all dimensions. If that is true, then existence and the big bang are simply the observer slowing down from the speed of light, or perhaps a particle that is changing states from the speed of light to something less. But what caused that particle/observer to change states? If I were a theist, I would say God. If I were a science fiction writer, I would say that particles changes states in our universe all the time, and that a different universe exists in each changed particle (i.e. we are just a particle changing states in someone else's universe). But I'm neither, so I have no idea. What do you think?
