Gravity points down.  That's where things fall.  Down.  And saying "the fires didn't weaken" does not make it true.  It doesn't even make an argument.  It's more like random words.

Finally, there are huge differences between 7 and the towers.  For example, the primary support for the towers were the beams around the outside.  The primary support for the bldg 7 was far to the interior.  Again, just saying something isn't even an argument.

Does that make sense?
