/diy/ - Do It Yourself

If you take a 1m radius disk and spin it at 10k rpm, it would take about 2.6 years before you get a 1ms time difference. Counterintuitively, at that point the rotating clock would be 1ms behind the stopped one (rather than being ahead), as the acceleration of the stopwatch contributes more to the time dilation than its velocity. That could be measurable if you had 2 stopwatches perfectly synchronized somehow. Note though that the outer edge of the disk would be spinning at near mach 3 though and experience an acceleration of over 100000g. A normal stopwatch would not survive this and neither would a lot materials, so you'd have to do some impressive material engineering to address these issues. You'd also require some kind of cooling system or having the disk in vacuum, delicate balancing and of the disk, etc.

It'd be easier to build if you went for a smaller disk like 0.5m, but then you'd be stuck waiting over 40 years for a 1ms time difference. But anyway, that's probably also the reason why nobody has tried to measured time dilation in this way.
