The first collapsed floor was not due to a preceding collapsed floor... of course, unless we have some freaky causality loop from star trek
. I agree with you, however, your statement is ambiguous; the first collapse does have something to do with another collapse, the collapse that follows it. We agree that [some cause] caused a single floor or several close together cause the initial collapse that eventually brought down the building.
Yeah I know you know thermal expansion was real, fastom had earlier brought that into question… my professor got a kick out of reading fastom post, as did his colleagues, and the rest of the science department
