== verification of time dilation ==
At the end of the "Time Dilation" sub-section, I propose adding the following paragraph:
Since the 1960’s, the time-shifting effects predicted by general relativity have been tested by comparing clocks placed at different elevations in the earth’s gravitation field. The most recent measurements indicate that gravity’s effect on time is predictable to 7 parts per billion.<ref> 1 </ref> In this work, Holger Mueller and colleagues shot cesium atoms in an arc through a vacuum chamber. Using a laser they were able to bump some of the atoms to a slightly higher path. Then, they measured a small, but significant phase difference between the atoms in the two different arcs. These measurements provide strong support for Einstein’s theory of general relativity.
