Additionally, soon after the outbreak started China went through and eliminated a huge number of animals from wet markets and livestock farms...a reasonable response, but there was very little outside testing of those animals for viruses. They may well have wiped out the entire population of intermediate hosts.

I dont think there is a charge that has no mass. Light is not considered having a charge, protons and electrons are, and those have mass. Maybe I should have said 'charged particle' but it should be synonymous. Your link unfortunately does not answer the question.

Basically is it backlit or lit from the front. If you backlight the cup you are looking at the light that has passed from the light source through the cup and then reaches your eyes. If you put the light on the same side of the cup as you, then you are looking at light which hits the cup, reflects or scatters off the glass and gold and then reaches your eyes.
