    Einstein's theory of special relativity
  1. I suppose what it all comes down to for me is an attempt to explain Einstein’s concept of gravity in an accessible metaphor. Space-Time contraction when approaching the speed of light may take a while to understand, but the concept (if not the math) is not outside the ability of an interested pedestrian high-school graduate. Like me. So why not gravity? It may be “pop-sci” cartoons that help the understanding, but I’m a big fan of cartoons. And pop-sci, come to think of it. Aren’t you? How can anybody not like “Futurama”? Einstein’s ideas regarding gravity don’t seem as simple and strai
  2. I've been trying to wrap my head around Einstein’s explanation of gravity. I'd like some input to see if they way I'm visualizing could be correct, because it's a little different than what I've been seeing. In typical illustrations of Relativity and the force of gravity, Space-Time is a shown as a two dimensional grid. Mass (a planet) is pictured as forcing the grid down, warping the plane like a heavy weight on a pliable surface, or re-shaping it into a sort of cone-like funnel. What I see (on those iritating nights that thoughts of Relativity are keeping me awake) is the same two d
  3. I'm not a physics type guy, but I'm interested in Einstein, so this is more of a question than an answer. I've always assumed that the increase in mass was a direct result of the space dilation more than anything else. I know that I'm missing something here because that leaves out the energy being converted to mass, but I just don't have the physics to fully comprehend what it is. Or is that what it's all about? Energy being converted to mass?
  4. The topic description pretty well spells it out. Light travels at 186282 miles per second, a velocity at which time and space fully dilate, and where an infinite amount of energy would be required to for matter to travel at the same speed. OK, fine. So why light speed, in particular? And please don't answer "because if it traveled any faster it would go back in time", or "because that is as fast as it could go in normal space". I want to know why the two are dependent upon each other. A better way of putting it might be "What physical rule in our universe makes it impossible for light sp
  5. I appreciate everyones input, and I can't say that I disagree with the generally accepted interpretation of Special Relativity. It took me several months just to wrap my head around how Einstein came to his conclusions and what they mean (it really kind of grabs you and doesn't let go, doesn't it?), so I don't really feel qualified to disagree. I just have this itch in the back of my mind that says that there may be room somewhere for a different idea. If you'll indulge me just once more, I'd like to go just a little further and get some feedback on what's really bugging me. I'm not changing t
  6. Would the exchange of information at a speed faster than c be equivalent to sending information into the past?
  7. I have a different way of looking at Einstein than most, that makes faster than light travel possible, without bending any rules. At least, I think I do. Special Relativity says that space-time dilates at near light speed velocities, and that the time slows down for the traveler. As the old story goes, 100 years pass on earth, while only a few years pass for the traveler on the near light speed ship. This is not merely a matter of perception on the part of the either the traveler or the earthbound observer. This is the reality of the space that both parties inhabit. Relativity says that time
