Speed Of Light May Not Be Constant After All, Physicists Say

The speed of light is constant, or so textbooks say. But some scientists are exploring the possibility that this cosmic speed limit changes, a consequence of the nature of the vacuum of space. The definition of the speed of light has some broader ...Constant Force and Constant Motion

I see this problem all the time. The idea that if you apply a constant force on an object, it should move at a constant speed. Really, this is what Aristotle would say, right?
