Time is how we perceive distance in the fourth dimension of space.
The Lorentz equation for distance 's' between two events, which does not change with the speed of the observer, is :- s^2=(ct)^2-x^2-y^2-z^2.
If the observer sees two events occurring at the same place then the four dimensional distance between the two events is the measured time difference multiplied by the speed of light.
As the observer sees no distance between the events the observer must have been moving at the speed of light in the fourth dimension of space.
It follows that the universe is expanding at the speed of light in the fourth dimension.
From this the whole of the confused muddle that is called the science of Physics has been unraveled and is present on the web.
