Read an article today from LiveScience about how researchers have discovered a way to make the atomic clocks (the ones we use to set the actual time on everything from our computer to our TV to our smartphones) even more accurate. As they become more and more accurate, some of the underlying theories of physics may finally be able to be tested. Einstein's theory on relativity (which describes how gravity affects space-time) may finally be able to be tested, understood and possible proven (or disproven). While our every day lives won't really feel this change, there could be future developments for other scientists who require ultra-accurate time sources. Read the article for all the technical information.
