Same thread, later comment. But if not, then here:
Good layman’s summary of the science behind mask-wearing:

And still more about droplets and aerosols: I know these things take time but are we talking about weeks, or are we talking about months?
I seriously want to see your results.

Ok thanks. Those links are new this thread - you must have posted them on a different one.
You are right that there are elements of science involved with this conversation. What size particles typically result from coughing, sneezing, talking, breathing? How far do they travel? How long can the virus live in them at various temperatures? What particles get blocked by masks of various materials and construction?
But the question of whether masks are effective in responding to a virus goes way beyond the physics of particle transmission and filtration.
There are deep divisions among scientists regarding whether preventing exposure should even be the primary goal. Perhaps we should only wear masks around the very sick and the very old.
Big Pharma’s ability to create an effective vaccine pales by comparison to the human body’s proven ability to create antibodies - and natural immunity. It has allowed us to coexist with millions of potentially deadly microbes through our entire evolution. Exposure to the healthy majority of the population is required to develop natural immunity.
Should we bet on Big Pharma to save us, and artificially block the natural process of building immunity in the population? This is still an open question.
The scientific method is built around questions and assumptions. A real scientist would never be caught uttering Al Gore’s term “settled science.
Leftists like Al Gore always invoke science when trying to force their regulations on the citizens, and anyone who resists is called ignorant.
Let’s not make the same mistake.
