So how something can move faster than light. To move at the speed of light, mass must be 0. To move faster than light, what would the mass be?

- Freaky 10y agoEither it would have negative mass and imaginary energy, or it has negative energy and imaginary mass - http://math.ucr.edu/home/baez/physics/ParticleAndNuclear/tachyons.html http://math.ucr.edu/home/baez/physics/ParticleAndNuclear/tac...
- petewailes 10y agoThere isn't really such a thing as faster than light. It's more that light travels at c, than that c is the speed of light. By way of analogy, it'd be like having a chart with an x and y axis, and having a line going straight up the y axis, then asking "but how can we make it more along the y axis?". I realise in terms of numbers it makes sense, but in terms of physics it doesn't. There's no such thing as faster than light through spacetime. Travelling at c, your perception of time would have stopped. From that point, it can't become more stopped, any more than you can go faster.
