"I have not found data to substantiate that the conversational distance is higher outdoors than outdoors." And that's just silly.

You're wrong about the sunlight, Zeynep. Jose started with the claim that inactivation takes 5-30 minutes. Then it was 90% inactivation at 5 minutes, then 3. That puts the half life well below a minute, a figure reported in multiple papers.

As for gravity, yes, it's the same indoors and outdoors. But outdoors people spend a lot less time face to face. There are reasonable arguments for predominantly aerosol transmission. It baffles me that anyone would focus on this particular one. It's incredibly weak.

Need a theory of observed epidemiology that fits physics, virology, mitigations and their results. I've yet to encounter one on it being mainly droplets—close contact being important fits both theories, but little else does. (Where is all the close contact outdoors transmission?)

Has it ever occurred to you that there just isn't enough evidence to decide? The over certainty of some of the covid social media influencers drives me crazy. I guess you don't get a lot of followers when you say "we just don't know yet."

If sunlight was the explanation, there would still have been a load more evening outdoor super spreading events

Sunlight inactivates virus regardless of whether it's in aerosol or droplets.

I *think* Bryan bzdek / Jonathan Reid in Bristol found small differences in stability in trapped levitated droplets. But I'd also be surprised if major difference - RNA still same basic chemistry, and that would be the main photo damage, no?

That, and oxidative damage to unsaturated lipids in the envelope.
