Why are so few willing to discuss the science?

Well, they started with the fires and the evidence showed that there was a lot of fuel and the fire burned hot enough for their to be visible buckling of the towers' infrastructure. The fuel didn't disappear, it burned and the effects were obvious.

The alternate theories didn't start to develop right away - the NIST investigation eventually had to catch up with them years later and address them. They wouldn't have occurred to investigators because they came out of the imaginations of people who were trying to come up with them.

Those big fireballs were the result of the fuel burning up. Nothing else would have contributed to that huge fireball. I'd say more than 80% of the fuel burned off right there and then on each impact.

If fires really get that hot, then we have many buildings that are at risk of collapse due to fire.

The alternate theories came out with the inconsistency of the information in the reports coming out of the government.

They had the names of the highjackers, so it would be easy to follow those to Al Quaida - they could have already had those links on file.

Yes I recall the one untouched passport of one terrorist was found in all the rubble of the towers. That's some needle in a haystack. You'd think those fireballs would have taken care of anything that could burn. Sure we saw much paper being spewed from the towers after the impact, but one passport managed to survive which allowed the US to pin it on Al-Queda and identify all 19 hijackers?

Now with science (I guess if we stick with the OP) explain how that passport managed to survive?

Based on what ? It's hard to measure how much fuel produces a spectacular fireball isn't it?

Yes, if they had fires.

I agree with that, but inconsistency will happen when there are huge volumes of information. And the theories kept changing. Soon after the event, I remember two big theories were that the cellphone calls from plane passengers to relatives were faked, and that the WTC landowner was behind it. Those died, eventually, with the surviving theories being ones that could only be absolutely disproven by experts. And if you didn't trust the experts, or had a single self-described expert in your corner then you could cast doubt on the official story.

Leaving aside the science for a minute, there's no overarching story that can reasonably explain how these events happened other than the terrorists being behind it. The motive, the command structure, the risk/benefits to such a project, the execution do not make sense at all.

In an event of this size, there are millions of events and therefore many anomalies and strange coincidences. The planting of a passport would be part of a conspiracy if they wanted to deceive people as to who was in the plane right ? But people were in that plane. I don't think people doubt that. And it was flown by somebody, so what's the idea there ?

It's more likely that this is just an odd coincidence - I don't see how or why suggesting a different identity to the pilots achieves anything for the conspiracy.

Now with science (I guess if we stick with the OP) explain how that passport managed to survive?

It's random. The nose of the plane was destroyed first, with debris scattered a fraction of a second before the explosions.

According to the designers, the towers were able to sustain multiple hits from aircraft smaller than the 737.

Cite?

Did they simply focus on the fires as being the sole reason for the collapse? Those fires could not have gotten that hot as most of the fuel burned off on the impact of each aircraft. The wings carry most of the fuel.

Cite? The fact that there was so much smoke coming from the towers right up until collapse suggests the fires were blazing away quite well.

The impact got through the outside mesh, but not so sure that it got to the core. The aluminum aircraft was shredded by the iron exoskeleton of the building.

The impact of the aircraft caused the load to shift from the outer frame to the inner core which was subsequently weakened by fire.

They found lots of personal effects from lots of passengers. Not sure why a passport surviving is so unusual.
