#quantum

So, after all, what is time dilation? You see the picture, if a particle is unmoving, stationary, it will move forward at the maximum rate possible, but the more the particle moves through the space, the less it has influence in the time dimension, then dilating the time dimension.

Topics: Quantum computing. #quantum
