Engineers only please...is there any truth to the argument that the WTCs were destroyed with explosives?

I've been hearing a lot of conspiracy theories on this matter lately, and I was just wondering what some scientists/structural engineers thought about it. Ive heard some say that the heat of the airplane crash would not be hot enough to melt the steel beams, and also that it looked like there were placed explosives.

was the big bang the beginning of all (time, space etc) or is there a multiverse?...?

in my view, by history, the human kind was always looking towards the world by taking itself into the center. first, earth was the only planet, then the sun circled around earth, then sun was the center, then the big bang. what if this was by far not the last station in which we are playing a more and more obvious side-role? what if our universe stands next to million others, like a bubble in a giant bubble bath?
