So hear me out.
What if the entire speed of light limit is true only for light?
Now you may say that the entirety of modern physics is based on relativity which is based on the speed limit true for light.
But what if that is just a special case?
That would mean that the wave functions are also variable when mass is present or not in the equation.
What if relativistic effects on objects containing mass is just a 'light boom effect' ?
