"Start with e=mc2. This has been accurately measured as true." By whom? If tachyons were the new measure for fastest thing in the universe I guarantee you that the minimum difference between the old equation and the new one would make no noticeable difference. "People always talk about how things get heavier when they go faster" Who says so and who has proved that? You may get heavier by adding gravitron collisions to your particles, and that doesn't mean it is a law. "As you go faster, you have more energy. Since you have more energy you are heavier." I didn´t know energy had weight, but again, it may be explainable. "You find that as you get closer to c your mass goes to infinity." Unproven. Photons travel at the speed of light and they don't have mass. "This is probably not enough to convince you" Nop. "The light always moved at the same speed." Who say so? What if light has different speeds based on huge gravitational forces? Nothing to do with the curvature of spacetime (which I call bullshit) but with the perception of the observer. "Start with that assumption, and create rational formulas to explain how that could work." If your assumptions are wrong your formulas will also be wrong. "A clear explanation that anyone can understand." It is not that I don't understand it, it is just that I don't accept it as truth. "The final question is, ok you can't send matter faster than light" I am not talking about matter, it may well be a limit for matter, but how about other forms of known and unknown energy or radiation? Relativism is ok regarding the observer and using light as a measurement unit. But just throwing a huge number c2 in a formula doesn't make it right, just the same as throwing another t2 (speed of tachyons squared) would make it right either. Here is my formula: E=mt2 My question stands: why the speed of light squared?

"I didn´t know energy had weight, but again, it may be explainable." If you didn't know that energy had weight, then how could you possibly understand anything whatsoever about relativity? You talk about "adding graviton collisions". Go way way simpler. Energy has weight. Speed things up, they are heavier. Want to speed it even more? You need to add even more energy than the first time because now you are also speeding up the energy [weight] from before. Run the math. Solve. Final result c=speed_limit. The math is easy, don't take my word for it. Do you know any calculus? That's all you need for the math. You are talking about advanced topics like gravitons and tachyons, without even understanding the simple topics like energy having weight [mass]. How do we know that the weight of energy is equal to the energy times c_squared? You can measure it, that's how. The earliest particle accelerators can do it. Actually you don't even need a particle accelerator. Take a gamma ray (a photon), cause it to split into an electron and an anti-electron (using a magnet). Measure the energy of the photon that is left over. The difference is the energy that was consumed in making the electron and anti-electron. Measure the mass [weight] of a single electron. Do math. Result: e=mc2 (i.e. mass of an electron * 2 * c_squared + energy of leftover photon = energy of starting photon).
