9/11 meets Sheldon Cooper?

I wish Sheldon would use his awesome mind and finally show people that physics of that day doesn't add up, steel melts at 2800 degrees, jet fuels burns at about 1000-1800 degrees.

    There is so much about 9/11 that has never been answered, the fact that the twin towers are the only buildings in history to collapse due to a fire, the way the buildings collapsed, the FACT that all THE WRECKAGE WAS SHIPPED ABROAD as soon as possible, the FACT that even ROLLS ROYCE themselves have said that the engines from the planes were not the type of engine used on the type of plane (b757) that was said to be responsible.

    -WTC leaseholder Larry Silverstein admitted that building 7 was pulled down by a controlled demolition: http://www.youtube.com/watch?v=-jPzAakHPpk

    (He changed his story the next day)

    -Official version claims the towers collapsed due to 'pancake effect', meaning the floors came detached from steel girders and fell on top of each other, collapsing the tower. If that's the case, why weren't any of the (core column) steel girders left standing? http://4.bp.blogspot.com/-ub_6RM9p6nY/TjWusVortWI/...

    -Pictures show smoke coming from the basement seconds before the plane hits. People (including firefighters and employees) also heard explosions from below the towers, moments before the plane hit. PEOPLE WERE KILLED AND SOME SERIOUSLY INJURED IN THE BASEMENT.

    -Pictures show steel girders with diagonal cuts in the them. This is exactly how controlled demolitions bring down buildings.

    -Designers of the WTC say they were built to withstand MULTIPLE impacts from such an aircraft.

    -Official version states the plane that hit the pentagon 'vaporised' which is why very little traces can be found. Yet they managed to find DNA to identify all of the victims on board. Furthermore the building didn't 'vaporise' in any way. What type of plane vaporises, leaving the building and human DNA relatively undamaged.

    -The passport of one of the hijackers in the aircraft was supposedly found in the rubble at the WTC. It's clearly impossible for any personal effects to survive the impact and explosion, therefore it must have been planted.

    -All CCTV from around the pentagon has been removed and never released. Why do that if there is nothing to hide? 86 CCTV cameras no airplane???

    **PLEASE NOTE: 'Mark F' is a multiple account troll who searches for and responds to every question regarding 9/11 sometimes answering one question using two or three of his accounts to parrot the governments lies and gives other answers up to eight thumbs down who don't agree. (How sick is that?) He spends his whole life on YA and seems to have no other hobbies, interests, friends or even a job.

    Here in the real world we know you are talking nonsense.

    No steel "melted" on 9/11 and the only people who claim it did are conspiracy nutters who don't understand physics. Also, people like me who actually have some understanding of what happened on 9/11 know the jet fuel burned off after about a minute. The subsequent office fires which raged for up to an hour or more (depending on the building) were more than hot enough to SOFTEN the steel the point where it could no longer support the weight above. That happens at something like HALF of the steels melting point.

    If you like physics here is some for you, done by an actual physicist. Let me know what you think and if you have any complaints, make sure you show your work.

    Take your tin-foil hat and your Glen Beck nut-bag conspiracies elsewhere. The steel girders didn't have to melt, they just had to be softened enough for the hundreds of tons of weight above them to cause them to collapse.

    It didn't just melt. It shattered and collapsed. Why can't you 'conspricists' get over it and move on. You give me some reasons why the goverment did it and what proof you actually have
