Basic physics tells us that a thin plastic sphere (ping pong ball) can not cut through a wooden structure (paddle). So why did many Americans watching Mythbusters (or Jimmy Fallon) believe that such can happen without leaving any debris on the outside of the paddle.

The trouble with "basic" physics is that the collision of a fast moving aircraft with a relatively thin walled (and lots of open space on the interior) building is anything but basic. It can't be modeled using the static solid body physics of "basic" physics. That is why the NIST (and others) need to use complex dynamic models to understand the forces and interactions at play. And while it might not make common sense, the events are within the realm of physics.

I expect these videos won't dissuade your position. But it is obvious you don't want a discussion, so I won't respond other than to post this message. Your statement....You would rather be spoon fed some story that gives you some brown person to hate. ... does not suggest you are open to a true discussion.

As a free thinker, I am open to considering the evidence and conclusions based upon the evidence. I also saw the planes strike (albeit on video) the towers and penetrate into them. While there might be discussions about some of the smaller details, I do believe that the planes struck and penetrated the buildings causing their collapse.

The plane was a projectile, going at amazing speed. Smaller items have penetrated larger items. Explain how pieces of straw have been able to penetrate tree trunks during a tornado or hurricane. You also have to take into account the Twin Towers' structure: [tms.org]

It depends on the velocity and mass. A drop of rain traveling at the speed of sound can wreak havoc on what it hits.

Your initial ASSumption, that a plane could not penetrate a building, is just plain wrong. (See excellent comments, above, about arrows, & high winds causing grass to penetrate wood, by Mortal & WilliamFleming.
Everything after that therefore fails.

I have no opinions on the subject at hand, but I would like to point out that sometimes after a tornado straws are found to have been driven through trees. Remember also, there was s lot of glass in those buildings.

By all means, let’s not have hatred and intolerance. Especially let’s not blame one fourth of the world’s population for the actions of a few people.
