Movement of particle

  1. Aug 18, 2012 #1
    For a particle to travel from point A to point B at the smallest scale, is there a distance in which the particle has to teleport since its shape doesn't change. Let's say the distance it travels is 0.0000000001, but the particle still need to travel that distance without it being 0.

    A particle does not have a shape, and it does not teleport around. Why do you think it has to?

    And with a speed of 0.0000000001, it will reach the target in time 1 (add dimensions if you like).
    Where is the relation to quantum physics?

    well, I'm wondering what the smallest traveling distance is.

    Hey fred:

    It is believed the smallest distance is around Planck scale, about 10-33 cm.

    At this distance chaotic quantum foam seems to begin to destroy traditional space,time, mass,etc....quantum field theory begins to break down.

    Like when wind blow the tops off waves, called spume, the froth obscures the interface......where does the neat divide between air and water go??

    You can read in Wikipedia "Planck scale".....

    Just how far a particle must 'move' depends on your particle model and environment: The Standard Model posits point particles; Heisenberg uncertainty is also a factor and the Pauli exclusion principle may also be a limiting factor.
