The question you need to ask yourself is do you understand? And if you do, why are you worried about what other people may or may not understand? Regardless, one only needs to understand that the NIST investigation excludes critical components, uses fabricated data, does not conform to investigative standards that NIST publishes and expects all investigations to conform to.and is a theory that is proven to be impossible. The videos show step by step the major differences between real known data and NIST's selective data and how real data, when used correctly renders NIST's theory completely invalid. More importantly though, NIST was not tasked by Congress to concoct theories, they were tasked with investigating how and why the 3 towers collapsed on 9/11. So NIST failed to do its job and created worthless reports as a result. Having said that, qualified experts in relevant disciplines fully understand and have exposed NIST's fraud in detail. What's incredibly evil and vile about that fraud is that this was supposed to be an investigation into the worst terrorist attack in modern US history that murdered 3,000 innocent people. And NIST's theory is being used in part as pretext to wage perpetual war that has murdered hundreds of thousands of innocent people and otherwise destroyed millions of lives, something that is still ongoing.
