When you explain where I'm asking someone to; "perform a logically impossible action - such as proving a negative - in order to win an argument", I'll stop. Until that time, I don't know what you are talking about?
Fine. Right here:
"I've yet to see proof that thermite or a derivative could not be used to create a core failure."
The proof you require would demand us proving a negative, i.e, that thermite could NOT be used. That is logically impossible. We can rule it out based on evidence, and have done so, but we can't prove it. The proper sentence, using the right burden of evidence would be this:
"I've yet to see proof that thermite or a derivative COULD be used to create a core failure".
This requires positive evidence, and the burden rests on the person suggesting that thermite did play a role in bringing down the towers.
Regarding your summary;
You have not proven there was no evidence of explosives,
Again with reversing the burden of evidence? Neither I or anyone else have to prove that there were no evidence for explosives. You and others like you asserting that there were explosives have to provide such evidence. You have not. The logical conclusion is that no explosives were used.
some, not all, of the videos captured collapse sound,
The videos where the cameras were close to the towers did capture the sound of the collapse. They did not capture any sounds of explosions.
I'm not qualified to state whether the sound of demolitions was, or was not embedded in the sound recordings,
I thought you said you were an expert? Nevertheless, alienentity, who
is an expert in this has checked, and there are no sounds of demolition. Only the clear sound of collapse. Really, no further analysis is needed. It's cut and dry: We can hear the collapse but no demolition charges - conclusion: there were no demolition charges.
I don't know what the hush-a-boom reference is about, the mics did not pick up the collapses "just fine" and I give that as my professional opinion.
I'm just as qualified as you to say that the mics did pick up the collapses just fine. As evidence, I point you to the videos of the collapses where we can clearly hear them.
I also don't like the derogatory term "twoofer".
Tough.
If you use that term again don't expect a reply.
Don't care.
I manage not to insult you with such a label and I think can show me the same respect. Okay?
You insult the memory of the 3000 people that died that day with your loony assertions. Expect no respect from me.
