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.

You can simulate the 4004 like the 6502 (see https://t.me/c/1123530133/73), but it seems you need to run on an older Java version.
