9/11 False Flag: 9/11 Truth for Complete Retards: Wrap Your Head Around One Thing


Premise, official story: a few floors at the top collapsed, starting a chain reaction in which the collapse of each additional floor made the total mass heavier, and driving it faster and faster toward the ground. This is why the towers fell at virtual free-fall acceleration (virtual as in 'very close to.') Free fall acceleration is the speed any object falls through thin air to the ground. It is 10 meters per second, per second (for every second an object is falling, it goes another 10 meters per second faster. So a baseball falling for 3 seconds attains the speed of 30 meters per second.)

Problem: Things that are heavier do not go faster than things that are lighter, discounting negligible differences in air resistance. In a vacuum, even a feather and a bowling ball would fall at the same speed. The towers "fell" at the same rate as they would have fallen through thin air. But steel, even soft steel, is thousands of times denser than air.

Therefore, mass does not accelerate as it accumulates. In fact, it can only go much slower than free-fall acceleration as it meets resistance. This is common sense and what would have happened on 9/11 if the upper floors of the towers had collapsed. The upper floors would have met the resistance of floors below them, slowed down, and stopped. The mass could not have fallen through steel at the same speed it would fall through thin air.

There are many things wrong with the official story. You've heard them all by now. Wrap your mind around this iron law of Newtonian physics, proven by Galileo, and you will see that the collapsing mass could not have gone faster as the mass got heavier. Therefore the official explanation for how the towers disappeared so quickly is false.

Congratulations. You are no longer a dumbed-down American. You know what the rest of the world which gets a science education in high school knows: that the official 9/11 story is impossible. Not suspicious. Not full of questions. But flat-out, physically IMPOSSIBLE.

By the way, the debate over whether heavy things fall faster than light things has been going on since Aristotle. Galileo settled it. Galileo also settled that the Earth goes around the sun. That's how far into the Dark Ages 9/11 has taken us.

9/11 story problem: Which 15 story block will hit the ground first?
9380276396_9b8688d34c.jpg

Answer:

On 9/11 they both hit the ground at virtually the same time!

-If the 15 story section is falling at free fall speed ...

-All of its gravitational potential energy is converted to Kinetic Energy (movement)

-It is not available to do the work of "crushing" the building below!

-It would have to slow down in order to do any other work, i.e., "crushing 80,000 tons of structural steel below.

First of all, I agree that 9/11 Truth is for dummies.

Aside from that, this is the same attempt at a false argument that you've copied-and-pasted before. The 'official story' does not state that the rate of collapse accelerated, so that is a strawman argument.

Another strawman: The towers fell at the same speed that they would have in thin air. FALSE. But keep repeating it, maybe repetition will make it true.

This is sheer idiocy, and you clearly don't understand even the most basic ideas about physics. Granted, you didn't write the article, but you were once again sucked into the rabbit-hole.

"Wrap your mind around this iron law of Newtonian physics, proven by Galileo, and you will see that the collapsing mass could not have gone faster as the mass got heavier."

Sir Isaac Newton was born the year Galileo died, in 1642, so how could Galileo “prove” Newtonian physics? Incidentally, Galileo was imprisoned by the true church at the time of his death as a heretic.

Why did it collapse? It was not hit by the jets.

It was damaged by falling debris from the Twin Towers, and then left to burn for several hours, when firefighters had already stated that it was structurally unstable and would collapse. On the other side of the coin, what did a building that collapsed, that most people don't even know about, along with other WTC buildings, have to do with some conspiracy? What role did that play? I've never heard anyone make sense out of that angle.

They blew up WTC7 because....BECAUSE WHAT? :confused:

Because that was the building that had all the bodies of the demolition teams that rigged the WTC after they were executed to keep them quiet, sheesh!!!!

Correct me if I'm wrong but I think the tower 7 angle is that there were records upon records in there that made it convienient thar the building collapsed.

I would elaborate on the documents but frankly I dont care nor do I remember. Blessings!

That makes sense, because in order to destroy computer files, you need to demolish an entire building.

I recently looked at some porn on my computer, but instead of clearing my cache and all the things I had searched for on Google, I blew it up with some dynamite. ^_^

An an engineer, I can tell you that stuff like this makes me want to weep. :doh:
Yeah.

Here's what my physics education teaches me. Impact forces go as FT=MV
Where T is in some sense the time period over which the impact is spread out (say due to structural deformation spreading the impact over time) and MV is the momentum of the impact. F gets transmitted over the remaining members. Yes this is pretty idealized and there's a simultaneity problem (F will determine structural deformation which will determine T which will determine F...) but it's good enough for order one estimates.

That said, floor height at the 1&2 WTC was on average 12 feet. A single floor collapsing 12 feet will have all the velocity of a 12 foot fall plus all the mass of the building above the collapsed floor. Given the components are steel and steel (vertical cross beam under compression), deformation will be minimal and impact forces will be pretty large. At a first order estimate, 10 to 100 times the normal load of the floors above the collapse point. Here's the math.

normal load:
F = mg = 9.8 * m

impact load:
F = mv/t

Ratio: (v/t) / (9.8)

Approximate t? 1/100th of a second

More exact v: 7 m/s

Ratio: 700/9.8 ~ 70x the normal load force

Notice the sensitivity of the calculation to the impact time. I pulled 1/100th of a second out of thin air, but given the incredible rigidity of steel, I don't think it's totally crazy.

Anyway, the point being that a steel member can't support a building that it suddenly finds 70x heavier than it was.

And as for that nonsense about the collapse not accelerating, each non-damaged floor should provide, in some sense, a constant resistance on the way down. But every floor collapsed is additional mass, additional force. So there should still be a tendency accelerate even if you were thinking you could get away with making the assumption that an object falling through heavy resistance should quickly reach a slow terminal velocity.

I find these discussions to be about as useful as those debates about what might have happened if George Armstrong Custer had done something different at the Little Big Horn.

He didn't, what happened happened, it can't be changed, and what possible difference is it going to make now?

If Napoleon hadn't invaded Russia.....

If the dikes had been upgraded, then when Hurricane Katrina hit.....

The CIA was really behind John F. Kennedy's assassination because.....

Henry Ford should have known when he introduced the Edsel that.....

People: what difference does it make? 9/11 happened, nearly 3,000 people were killed, and it was one of the most tragic days in our history. Flogging this dead horse is not going to bring them back, or put those towers back up, or keep the terrorist scumbags who flew the airliners from doing what they did.

It's over. Let's learn what we can from what took place, take steps to avoid having it take place again, honor the fallen, and move on. Give the conspiracy theories a rest. Sheesh.

As much as I reject the claims of conspiracy theorists, I don't think any of us should pretend that it wouldn't make a difference if the government actually had killed 3000 of our own citizens.

But every floor collapsed is additional mass, additional force. So there should still be a tendency accelerate even if you were thinking you could get away with making the assumption that an object falling through heavy resistance should quickly reach a slow terminal velocity.

Additional mass does not equal additional acceleration. That is exactly what Galileo proved and what makes the official collapse dynamic absurd. It is so absurd that NIST would not describe it in its report, it was left to shills in the media to fill out the "domino effect" fantasy physics. The NIST report stops at the initiation of the collapse. Even they were too embarrassed to put their names on such an absurd theory. I guess they didn't want their grandchildren to think they were idiots.

The idea that a few floors of falling 3-inch thick, specially lightweight concrete, and the truss assemblies, can make 90 stronger, lower floors give way is something only dumbed-down Americans would believe, who don't even have to take algebra anymore.

That is the same as believing that Wile E. Coyote, when he falls off a cliff, makes a deep hole in the ground, instead of being squashed flat because the ground is much harder than he is.

You used the 'additional acceleration' strawman again. It isn't a feature of the collapses.

Have the dude you copied-and-pasted this tripe from submit his ridiculous 'it should have slowed and then come to a stop' nonsense to a peer-reviewed engineering or physics journal, or continue to get laughed at.

Like this --->^_^

To be completely honest, for me, I do not ask wither or not my government was behind the events of 911. I just ask myself if I would put it beyond their capabilities.

Would my government kill American citizen's in order to justify it's own means?

Would Bush lie?

Could there be some agenda?

I will never be able to say definitely: yes the government did it. However I can not say they are incapable of such an act either. Can you?

My favorite 'conspiracy' clips.
