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.

Ok, it’s been a while since it took physics so if I’m wrong someone can correct me:
No, moving charge doesn’t have kinetic energy because it has no mass. The link between photon frequency and energy is called the Planck Relation.

Concentration is important too.
Take 30 tablets a day and you will overdose and your liver will die in days.
Lower doses: Studies have proven that there is no affect on lifespan or other medical conditions from healthy people taking aspirin every day.

Was hoping to see someone linking to this video, Sabine goes into way more depth than anyone else I've heard explain it

How do you shine light on something vs through something? And I agree that the whole complementary color thing doesn't tell us much about the light inherently but it still seems useful (or at least interesting) to determine what color we perceive things to be.

> In other words, different wavelengths of light have different energies.
Is that only because shorter wavelengths lead to more oscillations per time, thus more kinetic energy in the affected charge? Or is there another reason for higher frequency light containing more energy?

No one suggests raccoon dogs are the reservoir. They suggest they were an intermediate host between bats and humans, as has happened with all the other bat coronaviruses that have jumped into humans.
