Hi there, I have a question for you pros on this site. If an observer were to reach the speed of light, would time dilate to a stop? Now I have another question about the nature of matter and light. I've made this observation: Matter has 3 physical dimensions (length, width, height) and one "movement" dimension - time Light has 2 physical dimensions (electricity and magnetism) and one "movement" dimension - out in all directions in time. Light by nature is 2 dimensional - projections in your eye or on a screen - any image in fact - is 2 dimensional. If you want to get from matter to light you have to multiply the matter by c^2 to get that amount of light. So you have 4d matter, 3d light... now say you want 2 dimensions (one dimension of space, one dimension of time) wouldn't you just multiply the equivalent matter by c^2^2 and then if you wanted just 1 dimensional material (no spacial dimensions and one dimension of time) you just multiply the equivalent matter by c^2^2^2, or c^8 Just been having these ideas and I've read through Einstein's special theory - still not clear on how much time would mathematically dilate if one were to actually reach light speed.
