Showing that people with Covid can be asymptomatic is not evidence that asymptomatic people transmit the virus, and the article you linked to just leaps directly to the conclusion. Here's an actual paper from 2021 that shows that -- as you might expect -- that exhaled particles correlate with age, weight and viral load: https://www.pnas.org/content/118/8/e2021830118 https://www.pnas.org/content/118/8/e2021830118 In other words: older, fatter, sicker people are more likely to shed the kind of particles that facilitate transmission. They make a point of noting that nobody in their test under the age of 26 was a significant source of aerosol. Anyway, GP is not wrong. We could do these experiments, instead of just guessing.
