IMO, he's correct in his analysis of Zeno's paradoxes.

I cannot speculate as to why folks are concerned this changes physics - it merely demonstrates that some mathematico-physical concepts may be artifacts of the math.

The universe seems unaltered to me!

Old Zeno never convinced anybody. His lecture notes were preserved through the ages only because they were so odd. If you want true strangeness, though, check into Galileo's lab notes. The only one of the bunch that was worth anything was Marin Mersenne, and he wasn't even a scientist. Maybe there's something to be learned there.

Well, sure the universe is unaltered. But it helps to recall the effects of another theory -- relativity -- which also represented a demise of some mathematico-physic concepts.

If this analysis of (non-existent) time and motion is correct, it's likely to result in some really strange and interesting stuff.
