9/11 question... Do you know why a feather and a bowling ball dropped in a vacuum from the same height at the same time will reach the ground at the same time? The answer is because while in free fall they both weigh exactly the same, zero weight, and there is no force acting on them. So where did the weight and the force come from to destroy the twin towers when all of that weight was supported for 30 years? The NIST answer --> "Since the stories below the level of collapse initiation provided little resistance to the tremendous energy released by the *falling* building mass, the building section above came down **essentially in free fall**, as seen in videos"...But free fall means not **falling**, and it also means no weight, and no force. --> ukposts.info/have/v-deo/fWRkYXmdrKF2yKc.html

@davidmudry5622
@davidmudry5622 Рік тому
Question, is saying "dynamic effects" in this NIST document the same as saying "dynamic weight"? My understanding is that objects falling "essentially in free fall" would have very little weight of any kind with respect to their "static weight", or any falling objects that do not "slow" as they fall, can only have a maximum weight of a "static weight"? Am I right or wrong? NIST WTC Towers FAQ 31...? Quote word for word... "Since the stories below the level of collapse initiation provided little resistance to the tremendous energy released by the falling building mass, the building section above came down *essentially in free fall*, as seen in videos. As the stories below sequentially failed, the falling mass increased, further increasing the demand on the floors below, which were unable to arrest the moving mass." "In other words, the momentum falling on the supporting structure below, which was designed to support only the static weight of the floors above and not any dynamic effects due to the downward momentum, so greatly exceeded the strength capacity of the structure below that the structure below was unable to stop or even to slow the falling mass. The downward momentum grew larger directly proportional to the increasing falling mass." Now can you envision a falling bottle that falls faster and faster and at the same time the water squirts out harder and harder? This is what the USA government is telling you happened on 9/11.

The falling water bottle was an awesome way to demonstrate the equivalence principle. Brian Greene mentions very quickly that the curvature in time as well as space is important and doesn't go into it more, but he means something like this: the rubber sheet represents spatial curvature and you can slice spacetime so you have many copies of the rubber sheet stacked together. Moving forward through time forces you to move upward through the stack, but the *true* time direction you experience gets pulled slightly inward by gravity, so your overall motion arises as the combination of both space AND time bending toward the sun.
@shcxatter2
@shcxatter2 5 років тому
Steven Kapturowski Holy shit, thank you for that comment! It made me think deeper into the problem, and I think I finally got it! So basically, it's like time is just another spacial dimension, in which we are moving with constant velocity(which we preceive as time passing by) at all times, and the curvature, which mass produces, extends into the future(which is basically just a direction if we consider time as a spacial dimension), and the fact that objects with mass get drawn into that curvature is due to that constant movement in time!

It's even stronger than that. The overwhelming majority of the acceleration we experience towards the earth - and everything experiences towards everything else - comes from the curvature in time specifically, not of space. Spatial curvature contributes to more exotic effects like lensing and black hole dynamics.
@MrFlameRad

@@jmcsquared18 exactly I was just going to explain that. For the most part, gravity is just matter bending space so that relative to spacetime curvature, you're actually not moving through space at all but only through time when you and another object of mass accelerate towards one another.

Hey if you guys want to understand more about how special and general relativity works, how humans' thoughts on the matter have evolved with the work of Einstein and other key scientists, or if you just need more examples to try to really wrap your head around a lot of the concepts, check out the Space, Time and Einstein course at www.worldscienceu.com. Brian Greene does a really good job, and the courses do a great job at making these mind blowing things relatively easy to understand.

But Brian Greene said the water is squirting out the holes because gravity is pulling down on the water. "Since the stories below the level of collapse initiation provided little resistance to the tremendous energy released by the falling building mass, the building section above came down **essentially in free fall**, as seen in videos"...But free fall means not **falling**, and it also means no weight, and no force. --> ukposts.info/have/v-deo/fWRkYXmdrKF2yKc.html

"So Albert Einstein says that space-time is a 4-dimensional hausdorff differential manifold, on which a metric tensor is imposed that solves the Einstein field equations, and that metric tensor gives rise to geodesics, and objects that are not experiencing any other force will move along the geodesics described by that metric." In case you wanted to look anything up. ;)
