Here is a possible explanation.
Time is the propagation of electromagnetic radiation,time is light.
The speed of light is a constant because there is no way to
detect time changing speed in your own frame of reference.
The speed of time-light is only an operant constant.
The universe is filled with electromagnetic radiation,
light has a finite speed possibly because light must travel through itself,
this could be the limiting factor.Only light can travel at the speed
of light because light is time. If you could travel at the
speed of time,for you no more time can pass.AS you approach the speed
of time-light,time-light gains on you less and less and time-light for you slows down
but you can not detect this until you return to the clock you left at home.
You can't measure the contraction of the length of an object with a ruler
that is contracting with the object,time-light is the ruler.
If light traveled at an infinite speed,reality would end with one spike
in an infinitely short time.
The universe must be AC.
