Please don't waste time with stupid questions that have obvious answers. We are discussing a nanothermite hypothesis here. You scoffed at the idea that a thermitic destructive process through 260-something columns would not take 60 to 90 minutes - a time that I noted because that is the observed time to collapse in the towers.
I asked you how much time you think it would take. It's a simple answer - isn't it? Is this stumping you? If you can't answer it, we'll end the discussion here. I'll assume you really have no clue, which is probably the truest answer here.
Let me explain in detail because you obviously aren't getting it.
In order for you supposed timeframe to be applicable, you need to explain HOW you think that columns of an individual floor were cut. What was the process? Each process would have an impact on the length of time it would take. Using 260 columns, here is each scenario..
1. All of the 260 columns were cut one by one in succession. That being, the first column was cut, then the second column was cut, then the third column was cut, etc.
2. Groups of columns were cut in succession. Group A (consisting of the north face perimeter columns), followed by Group B (south face perimeter columns), followed by group C (15 core columns), etc.
3. ALL 260 columns were cut at the same time
Do you get it now? Obviously cutting all of your 260 columns at the same time will result in a different timeframe then if you cut one column, then the next, then the next.
If you use scenario 3 and surmise that it took 10 minutes total to cut through the largest column, then that is the LARGEST timeframe you can apply to any column on that floor. So cutting ALL 260 columns at the same time would take no longer then 10 minutes.
So which scenario do you think happened? According to the majority of truthers, the columns were cut SIMULTANEOUSLY. If this is the scenario you choose, then you are suggesting that the thermitic material took 60 to 90 minutes to cut through the largest column.
