Your own statement disproves your theory. If you can't travel away or towards the source, you'll never notice a difference no matter how fast you go. Therefore, no time dilation (or Doppler shift of the "light source" you posited above, which amounts to the same thing in your theory.) Since both the Doppler effect and time dilation have been experimentally shown to exist, then your "4D time wave" theory must be wrong, as it contradicts the experimental data.
