I have no logical answer, so I will toss this bullshit out there hoping that it sticks to the wall.

The science that says that for persistent trails to be made, there are conditions that must be met.


SRM stops at night, that's obvious to anyone that goes out and sees the stars. If they didn't stop at night, we would never see the stars, due to them being faint compared to the sun.


The lack of persistent trails at night proves an ongoing SRM project.
