Of course there is resistance, the debris of the exterior columns is coming down way faster than the building is in all the videos, plus the building came down in at least 14 seconds, no resistance would have made the building fall at 8 seconds. Nice try though
The core remains intact just like how the progressive collapse theory says it would after the floors collapsed and turned to rubble and dust.

The top of the North tower was tipping over and was almost completely clear of the underlying structure. So what was the downward force capable of crushing everything beneath it?
Why are we supposed to believe that physics just did not apply on that day?

It was? Care to show a picture of that
NIST 1-3, 6.8.7 "at the moment of collapse of WTC2 the top portion of the building was found to have moved to the west as it tilted to the southeast".
"No conclusive evidence was found to indicate that pre-collapse fires were sever enough to have a significant effect on the microstructure that would have resulted in weakening of the steel structure." NIST NCSTAR 1-3C, p. 235
no evidence the type of joining methods, materials, or welding procedures used was improper NIST 1-3 p.99
recovered bolts were stronger than typical. NIST 1-2 p.133
"no core column examined showed temp. above 250C" NIST 1-3 6.6.2
NCSTAR1-3 7.7.2 "because no steel was recovered from WTC7,it is not possable to make any statements about it's quality"
"NIST did not test for the residue from explosives or accelerants" wtc. nist. gov/pubs/factsheets/faqs_8_2006. htm
Shyam Sunder at 2008 NIST technical briefing
"the phenomenon that we saw on 9/11 that brought this particular building down was really thermal expansion, which occurs at lower temperatures."
"NIST is withholding 68,246 files. These records are currently exempt from disclosure. All input and results files of the ANSYS 16 story and the LS-DYNA 47-story global collapse models"

Why do you believe that?
Are you saying they only needed one column on each side to hold up all the floors above?
