Re: cords coil. Why?

Possibly (probably) down the manufacturing process. both the wire and the outer plastic sheath will be stored on spools during and after manufacture. i imagine they coil in the same direction they were on the spools, much like if you roll up a piece of paper and then flatten it out, it will re-roll ...

If we got rid of the sun, the moon would just carry on orbiting the Earth, but what would happen if we got rid of the Earth? Does anyone know if the Moon would likely settle in a orbit around the Sun, or be flung off? I suppose it would depend loads on the Moon's trajectory at the time of Earth-End,...

Re: Well, this could change things

But the fact that those neutrinos clearly traveled about the speed of light, and the possibility that neutrinos excited or accelerated in this experiment traveled faster, are not irreconcilable.

Re: Would this ever end? (infinities)

I'm feeling grumpy, so... Since this is a program I say that it is certain to terminate. After all, the integer range is finite. If it's 16-bit integers, then after 32767 we loop down to -32768. Therefore the program gets a fresh chance to hit zero after about every 65536/9 iterations. With 32-bit ...
