Who ever said the core caused the collapse moron?<quoted text>
Here's the reality.....
How could the core cause a global collapse, perfectly, on all four corners of all 3 buildings, when the pile driver force did not exist there?
And seriously, "perfectly on all four corners"?
Both towers tilted before collapsing and wtc 7 kinked in the area below the east penthouse so your claim is wrong as always.
And you don't understand physics so referencing forces is obviously beyond your intellevtual capacity to understand.
