Hi everybody! Yes, another crazy idea from an outsider, but sharpen your teeth those who use to eat crank meat for dinner, I'm going to give you a tough ride. Here is the general idea: since, at the atomic scale, energy is always quantized, I suggest that motion could be. I begin with a mind experiment: - Imagine two cars at rest on the same straight road but one km away from one another and heading in the same direction. - There is an emitter and a receiver in each car and the signal exchanged between them is about the speed from their speedometer. - One of the cars accelerates and decelerates for 10 seconds, so a signal is emitted every fraction of second indicating the speed at which the car is going. - Lets us admit that the signal will take more time to travel one km than the time it takes for the car to accelerate and decelerate to rest. - When the signal will arrive at the second car, at each fraction of second, its receiver will indicate exactly the speed at which it has to accelerate and decelerate. - While it does as precisely as it can, its own emitter will transmit the signal to the other car, which will repeat exactly the same move forward, and so on for the next car, indefinitely. If the energy to move the cars could be infinite, the signal absolutely precise, and the steps absolutely precise, this slinky kind of motion would never end. Now, replace the cars by two identical atoms linked together to form a molecule, and imagine that the energy they exchange to maintain their link is quantized, which means that it would have the form of a signal, which would have to be constant for their link to be constant. These two atoms, represented by their nuclei, are very far apart, like the two cars, far enough for the signal to take more time to travel that distance than for an atom to make a step towards the other atom. Lets assume now that one of them is forced to make such a step because it undergoes a push, and that the signal does not have time to reach the other atom before the step is finished. If the energy of their link has to stay the same, won't the two atoms be forced to proceed exactly like the two cars? Observed from far away, wouldn't the motion of that molecule look like an inertial motion?
