There is a reason science is a process and until you understand something you should keep your ******ned mouth shut.
Especially when all you have against 40+ years of hard science is computer models.
Massssskss was one of them. I warned early on that physics said masks could not work if the virus was in aerosols or transmitted in feces, no matter whether the feces were manually spread or through aerosols. We knew this was virtually certain when a mass-spread event happened twice in Wuhan and Hong Kong in apartments on the same vertical drain stack where there were no P-traps; the people infected did not know each other and thus any other form of transmission other than through fecal aerosol was wildly improbable. That was ignored. We then had the German meatpacking plant where everyone was wearing masks and yet a huge outbreak took place across tens of feet, a claimed impossibility. Yet it happened and was proved by RNA sequencing; the researchers were able to identify the index and daughter cases and thus conclusively prove that the infections happened in that plant via that route, despite masks.
Now MIT has weighed in and said the same thing. They try to sidestep the mask issue in their “research” but fail; nothing less than an N95, which is not a mask but rather a respirator, stops aerosols, and source control does not work even with N95s because when you exhale the positive pressure escapes around the edges and for aerosols goes right through the gaps. Workplaces and airlines have banned N95s with exhaust valves which preserve the seal on your face and thus are the only ones that will provide protection for you against inhaling said aerosol. Non-valved respirators repeatedly break said seal and thus render it ineffective within minutes. Don’t believe me? Put on an N95 without a valve and do some sanding where there’s lots of dust, when you take it off let me know what you find around the edges where the respirator used to be. This is why you want the ones with a valve and why the ones I have for such work have a valve…
