Question

 If you were at the back of a bus going the speed of light, and you were to run toward the front, would you be moving faster than the speed of light or turn into energy — TM, Ft. Bragg, NC?

Answer First, your bus can't be going at the speed of light because massive objects are strictly forbidden from traveling at that speed. Even to being traveling near the speed of light would require a fan... Read More »

You insist over and over again that it is impossible to go faster than the speed of light. This is completely and entirely untrue. Tachyons travel faster than light. They also go faster as they exert less and less energy. — K?

I'm afraid that you confuse the hypothetical with the actual. While people have hypothesized about superluminal particles called tachyons, they have never been observed and probably don't exist. Th... Read More »

I think that the speed of light could be broken by turning a very long lever. If the lever is long enough and you have enough power to turn it, the end of the lever will travel faster than the speed of light. Is this so — NL, Hong Kong?

I'm afraid that this technique won't work—the torque you would have to exert on the lever to make its end approach the speed of light would become infinite and the energy you would have to transf... Read More »

I understand that the speed of electricity varies with the conductor, but is supposedly 2/3 the speed of light. I had thought the speed would equal the speed of light. Why isn't it — AP?

Although electricity involves the movement of electrically charged particles through conducting materials, it can also be viewed in terms of electromagnetic waves. For example, programs that reach ... Read More »

Does light have mass If so, then how can it travel at the speed of light Doesn't the mass of an object (particle) approach infinity as its velocity approaches the speed of light?

Light has precisely zero mass and that makes all the difference. You're right that taking a massive particle up to the speed of light is impossible because doing so would, in a certain sense, give ... Read More »
