<random internet commentator tripe>This could be the basis of a future tricorder or Star Trek-like sensor array. Three ultra-sensitive clocks in an array should be able to infer mass and motion both for the unit and objects in the local area indirectly. Relativistic effects are minuscule, but not non-existent. Extremely-tuned clocks would have some pretty cool capabilities.</random internet commentator tripe>
- splat 13y agoOne thing I've spent some time thinking about is whether it would be possible to use atomic clocks to get a better measurement of the gravitational constant G. (G is by far the most poorly known of all the fundamental physical constants.) The idea would be to build a sphere whose mass is very precisely known and place one clock near the mass and one clock far away. By measuring the gravitational time dilation you could infer G. As I recall from my order of magnitude calculations, atomic clocks would have to improve in accuracy by four orders of magnitude or so before this would be feasible. So it would still be a long ways off.
- prateekj 13y agoGood point! The research group is still working on refining their system. So may be they will have another breakthrough in a year or two, you never know!
- infogulch 13y agoHow about a wolframalpha link to those calculations? Assuming they're simple enough. Also, would this require the clocks and mass to be far away from other large masses like the earth?
