- Strange things happen when you get close to the speed of light, and they become stranger still when you realize that your high school physics teachers (perhaps inadvertently) lied to you. Lots of you are sci-fi nerds, so I'm guessing that at least once in your lives you learned Newton's force equation, F=ma. Deciphering the symbols, it means that if you apply a constant force to a particle, it should experience a constant acceleration. Taken to its natural extremes, if I apply a force for long enough and the particle keeps accelerating, eventually it should exceed the speed of light. Voila! Newton's force equation (at least in the form it's normally written) is wrong.
