Electron microscope analysis of steel spheres from WTC site

So when the Discovery Channel (America's Scientific Channel of Record) said the impact from the jets knocked off the fire retardant and the av-gas heated the steel enough for it to sag and pull away from the exterior walls trasfering the load they had been carrying to the structure below resulting in the buildings pancaking you say what?

To quote it more exactly, the government report says 'and global collapse ensued'. That's it; it describes nothing and it explains nothing. Notice that I am calling for a sequential mechanism.

How much did a WTC floor weigh?
What is the impulse/momentum generated by a block this weight dropping 3 meters?
How does this compare to the typical load on the steel structure from say the 50 floors it would normally have to support?

Answer these three questions (it's very, very simple physics) and you'll realize that global collapse is indeed inevitable once the first floor goes.

There are legitimate questions to be raised about the collapse but it seems like you've picked the worst possible points. [img]/images/graemlins/blush.gif[/img]

You have not described a sequential mechanism, or pointed to a source that does describe it.

It would be very interesting if you would actually give that a try. Then we can see if that mechanism matches with what we see on the videotapes and the photographs, with the speed of the collapse, things like amount of thick dust, and so on.

NIST has not dared to do it.

Why should anyone try to "talk science" with you? From previous threads, it's pretty obvious that you REALLY want to believe in a conspiracy, and nothing anybody posts to the contrary will convince you otherwise. It's like trying to debate the existence of god with a NotReady, or the theory of evolution with Sharkey.

You're not creating these threads to start a debate, you're starting these threads to push your agenda.

did you look at the links in my post or not????

Yes, I have and the issue isn't clear to me. On the one hand we have images of clear silver-looking molton metal, and then we have images of clear orange-looking materials. So that doesn't settle the issue, and I'd like to know what the science behind it is.

Are you saying you don't want to talk science? Why are you posting then?

If the President was involved in this plot why was he so stunned when he heard about the first plane?

Also, do you not understand what a sequence is?
1. Plane hits tower, impact knocks off fire retardant material from beams.
2. Resulting fire from av-gas heats beams enough to cause sagging.
3. Sagging causes beams to pull away from external walls.
4. When support of external walls is removed floor collapses to floor underneath.
5. Weight of floors above causes floor to collapse onto floor underneath.
6. Pancake

Still waiting for someone to do that. Unless you consider "You're irrational and dishonest" debating.

Give an example of the sort of post which you would see as a good-faith attempt to debate the existence of God.

Er, molten aluminium will be orange at certain temperatures and silver at others, just like the heating element of your stove will be orange at certain temperatures and black at others. Black-body radiation and whatnot.
