"Matter that is stationary goes zero speed through space,....."

Is there any stationary matter?

"Is there any stationary matter?"

It depends on reference frame. From your reference frame, you are stationary. Even if you're driving your car, from your reference frame you are stationary while the street is moving. The equivalence principal says that there are no absolute reference frames, only local ones. Relativity theory says that for every reference frame, time and space are different, which leads to time (and space) dilation at near the speed of light. That's from the point of an observer who's local reference frame is stationary, not the object going near the speed of light. That object's local reference frame is also a stationary one.
