    What if only ONE of the Twin Towers had collapsed?

    Was thinking about this. This has NOTHING whatsoever to do with bonehead conspiracy theories. What would New York, the government etc. have done if only one of the Towers had collapsed?

    A scale model of the Twin Towers

    I've been wondering this for a while. Perhaps someone with the relevant education can help me with it. Ultimately, perhaps it would be a good way to discuss this with the CD theorists. Suppose we had an imaginary 1:100 scale model of the twin towers (41cm high) to demonstrate how the collapse...

    Alternate twin paradox.

    The twin paradox is easily solveable with general relativity. However, there is another form of the paradox which I have not been able to solve. The paradox has one assumption, the universe is closed. Ok, so here's how it goes. There are two probes, both with clocks strapped to them. Probe 1...

    Twin Paradox Question

    Help, please, I really can't quite get past the twin paradox thing in special relativity. I think I understand it, with time dialation and all, but here's what's puzzling: Twin one leaves the earth in his 1-g accelerating rocket and lets it burn for three months. After only a few weeks he's...

    Twin Prime conjecture still not proven...
