The other way to look at it, of course, is that a NASA scientist attempting to aid popular understanding of science, in his spare time, and maintaining restraint and civility despite provocation, is actually being remarkably down to earth, in the face of a pontificating ideologue bent on externalising his fears about his own sorry predicament.
Most of my questions pertaining to 9/11 aren't scientific, so I'm not interested in soliciting scientists, NASA or otherwise. I've followed the threads and I've read his posts and exchanges with Apollo 20, and others. Despite being a NASA scientist I don't think there is any way he could have enough (credible) information to make any meaningful conclusion about what happened on 9/11, other than the obvious. He wasn't part of the investigation, he wasn't on the scene, he didn't design the buildings, he didn't construct the buildings, he didn't supply the people who constructed the buildings.
He's resorting to some equations to draw conclusions about an incredibly complex event. I'm not convinced.
The nuance you haven't grasped here - despite Mackey having explicitly said it - is that he isn't claiming to have all the answers. He's trying to drag you, screaming and kicking, through a process.
The process is tainted by his being certain of the outcome. He already knows that all the conclusions he's going to draw will support what he believes happened. I could be accused of the same. However, unlike him, I'm willing to admit I don't know with certainty what happened, and I remain suspicious.
Once you formulate falsifiable views about a situation, more or less however trivial it may be, the process infects the rest of your thinking. Your world view is a vast mosaic of interrelated assessments; akin to a hologram, each part contains the germ of the whole. No thought exists in isolation from your ideology, and if you examine one in complete dispassionate honesty, the rest will probably follow.
The important distinction here is the one between an assertion that is logically falsifiable, and one that is
practically falsifiable. I don't believe there is much that can be said about 9/11 that falls in the latter category. We can't practically run experiments to recreate what happened on 9/11, it occurred in a sea of unknowns, and all we have are a few assumptions fueled by what seems to be obvious - that it was a terrorist attack by 19 hijackers.
My world view was dramatically altered when, as a natural skeptic, I questioned the money system that exists in the world. I learned that the supposed causes of inflation are an open lie, and that this has surreptitiously undermined the political system to the point where it is an unfunny joke. Based on this alternative interpretation of history, politics, and economics, I find the attributed motives of the hijackers to be laughable. This is the basic reason for my skepticism towards the official account, and the myriad contradictions (apparently of which there are none that any self-respecting JREFer will admit to) about what happened that day.
You have your own ideology that drives your own assumptions about 9/11, namely that irrational religious zealotry is a predominate political force in the world, as opposed to the more methodical, Machiavellian power-grabs using this as a premise.
If you can't think of a question, then you aren't playing the game. You play the game, and you will understand, eventually, that you don't disbelieve the 'official' narrative about 911 because of its own inadequacies, or the earth-shattering fruits of so many hours of precocious internet sleuthing, but because you don't want to believe it.
It's not that you don't understand the physical science of it - you arbitrarily cram 'anomalies' into any cracks that will bear the strain. The truth is you willfully misunderstand the politics of it, because you don't understand your own psychology.
[Sorry, rant over, I realise you intend this thread not to degenerate into mudslinging, but that just annoyed me]
I can think of plenty of questions I'd like answered, just none by an egotistical scientist on a computer forum. The process isn't motivated by an attempt to understand what really happened - wherever that may lead, but to convince himself yet again that he is right, and we are wrong.
