How do you know how tall those buildings are or how far away they are? Why do you trust scientists telling you distance and height but don't trust them about distance and height about the earth?

Wait, why does that Moderna vaccine need to use mRNA? Couldn't we just have a bunch of E. Coli or whatever produce the spike proteins and inject those to provoke an immune response?

Wouldn't that be simpler?

If we assume the crew use their sick days or report symptoms, then we just want the odds of pre/asymptomatic people who're infectious.

Say that's three days on either side of "day 0" for symptoms and half of cases are asymptomatic. Then that's 3 days worth of cases + 1.5 days worth of cases - 45,000 cases.

Multiplied by the number of crew involved (100?) divided by Florida's population of 21 million gives 1 in 4? 1 in 5 odds?

If COVID-19's such a big deal, why haven't they followed it up with a COVID-20?

I've got a somewhat retarded question for you guys. When you close your eyes, and you create a mental image of something, do you literally see it, as though your eyes are actually looking at that object? I've been reading about aphantasia, having no mind's eye. I can think of an apple and draw it from memory, imagine its shape and color in detail, but what I'm seeing with eyes closed doesn't change at all, just black. Is this normal?
