ANALYSIS AND CONCLUSION The conditions required for gravitational acceleration to occur have been known for centuries....
The condition under which a body is, literally, free to fall under the influence of the local gravitational field with no resistance to its acceleration....
The control that appears on the right in many of the animations is intended as a reminder of that, and also signals the beginning of a comparison....
We can know with certainty in some cases (like this one) what conditions exist beneath an object (or building) as it falls....
....even though we may not be able to see into the space beneath it as it does....
Buckled columns, whether one or a hundred, whether one at a time or all at once (or any combination thereof) don't just go from 100% to 0%
when they buckle, they steadily decrease in strength
while they buckle and that takes
time.
The mechanism of buckling (a mode of natural progressive structural failure), whether caused by heat....
....or by overloading....
....
absolutely cannot match or create the conditions required for gravitational acceleration to occur, it's literally impossible. There is no such thing as
progressive gravitational acceleration....
Some force must be introduced to quickly remove all support from beneath the literally falling visible upper part of the building seen in the video....
The
progressive collapse of the building (NIST probable collapse sequence starting with column 79 on the left)....
....that essentially happens
all at once....
....is
clearly physically inconsistent with what we
empirically know of natural progressive structural failure (defined as a time consuming process of individual/sequential/simultaneous failure involving one or a number of related structural components).
It's a physical impossibility for the lower part of the
asymmetrically damaged building (reportedly three core columns and nine perimeter columns)....
....to have naturally progressively collapsed in
any way that could result in the upper part of the building
symmetrically descending straight down through itself (NIST probable collapse sequence starting with column 79 circled below) at anything
near gravitational acceleration for
any period of time. The scenario playing out below is an
absolute physical impossibility....
....and there is
absolutely no mode or combination of modes of natural progressive structural failure driven
solely by gravity that can
ever give rise to the conditions required for free fall to have occurred at
any point during it's descent....
The scenario playing out below is an
absolute physical impossibility. Just as there is no such thing as
progressive gravitational acceleration, nor is there any known structural failure mode known as
natural progressive structural gravitational acceleration....
There is simply no point during a natural progressive gravity driven collapse of a steel frame skyscraper like this where one could say....
"Hold it.... right there! That's the point where all the steel columns and structural components that were supporting the building just a moment ago (with an area greater than that of a football field) will undoubtedly be found to be behaving in a manner very much like air (below left). It will take very careful calculation to tell the fall times apart during this free fall period of the ongoing progressive structural failure (below right)"....For the 2.25 seconds (eight stories, approximately 105 feet) that we
know the upper part of the building
literally fell at gravitational acceleration it
cannot have been using
any of it's potential energy to crush the building contents, columns and other structural components beneath it and undergo free fall
at the same time (as illustrated by this frangible impedance scenario)....
It's
physically impossible for the lower
asymmetrically damaged part of the building to have naturally progressively collapsed in a way that could result in the upper part of the building actually
accelerating as it descended
symmetrically straight down through itself, through the path of
maximum resistance (below right), and then, driven on
solely by gravity, actually
continue to accelerate so nearly to gravitational acceleration (below left) as to require
very careful calculation for any difference between the two to be detected....
Some
other force powerful enough to quickly remove
all support from beneath the upper part of the building as it descended
must be introduced to explain the observed rate of descent during the 2.25 second period of gravitational acceleration.
For the 2.25 seconds that the building
iliterally fell at gravitational acceleration, no
other force powerful enough to quickly remove
all support from beneath the upper part of the building was seen to be introduced from
outside the building, and no
other force powerful enough to quickly remove
all support from beneath the upper part of the building is known to have existed
inside the building as an element or normal function of it's infrastructure.
For a load supported by a column to descend at gravitational acceleration, all support
must be quickly removed, there's
absolutely no other way. It
must be knocked out, pulled out, blown out, vaporized, etc.
Since no eight story tall boulders were seen rumbling through Manhatten that day that could have quickly
knocked out all support....
....and no suspicious looking Frenchmen were spotted rigging for verinage (another form of controlled demolition) the night before that could have quickly
pulled out the support....
....and no bombs or rockets were seen to be dropped on/fired at it that could have quickly
blown out all support....
....and no giant laser beams or other secret weapons were being tested in the area that could have quickly
vaporized all support....
....and no
other force capable of quickly removing all support from beneath the upper part of the building existed in the building as a normal function of it's infrastructure (blue)....
....it
naturally follows that whatever the
other force was that
must be introduced to explain the observed 2.25 seconds of descent at gravitional acceleration, it
must have been introduced some time
before the event, and unless someone can show how the
other force that
must be introduced either
during or just
before the collapse of the building was introduced from
outside the building, or that it was already existing
inside the building as a normal function of it's infrastructure, the process of elimination really leaves
only one possible explanation for the building's behaviour.
Some energetic material powerful enough to quickly remove all support from beneath the upper part of the building during the 2.25 second period of gravitational acceleration
must have been physically transported
inside the building some time
before the event, it
had to be
brought in.
The explosion model is the
only one....
....that can
realistically match and empirically be
expected to create the conditions that we
know must have existed....
....beneath the
literally falling visible upper part of the building during its observed largely symmetrical descent at gravitational acceleration for approximately 105 feet in 2.25 seconds....
The undisputed (both the NIST and independent researchers alike agree) confirmed observation of a significant well defined period of gravitational acceleration....
....means that an explosion, or a number of explosions,
must have occurred that was powerful enough to quickly remove
all support from beneath the upper part of the building (below right), either all at once or incrementally in advance of its descent, permitting it to descend at gravitational acceleration for the observed period and under the conditions required (below left) for free fall to occur....
The building was brought down by explosives.The empirically established fact that WTC7 was brought down by explosives immediately shines a bright light on literally the
only ones who could possibly have carried out a covert domestic operation of this magnitude.... the
only ones who had exclusive 24/7 access to the highly secured building (WTC7).... the
only ones who were in complete control of the security system for the building.... the
only ones who had ready access to the quantity and quality of energetic materials required.... and the
only ones who had the required expertise in the effective use of said energetic materials. The fact is that
only the Department of Defense/Central Intelligence Agency could have done it.... just as one needn't be Isaac Newton to see there is no other possible explanation for the behavior of WTC7 other than energetic materials having been physically transported into the building, one needn't be Sherlock Holmes to see there is no other possible explanation as to who could have done it since the building was in perpetual lock down as a highly secured government facility.... it's elementary.
So to sum up, in this case anyway, one simple fact (free fall) leads to an inescapable conclusion (intentional demolition). That one simple fact and the inescapable conclusion it naturally leads to (as revealed by analysis), that WTC7 literally had to have been brought down by explosives, along with the fact (as revealed by the list of tenants) that personnel from the Department of Defense/Central Intelligence Agency are literally the only ones who could possibly have done it, really wraps up the whole thing (all the events of that day) in one nice neat little package.
