Before Einstein, it was generally accepted that you can't violate the forward progression of time, because "time" is not really a thing, it's the measurable effect of physical processes playing themselves out. So the states of the universe that we call the past no longer exist and cannot be returned to.

Then Einstein did this Space-Time thing in order to solve some problems with gravity and time dilation (under certain circumstances, physical processes slow down). And then he decided to make Time a dimension, like the three dimensions of space.

I am firmly on the side of Lorenz here and I think this is nonsense.
