Relativity now 10,000 times more accurate

Now physicists in the United States have gone a step further.

They have proved Einstein's theory with an accuracy 10,000 times greater than before, according to a paper published in the British journal Nature.

A team that included Nobel winner Steven Chu - now U.S. energy secretary - used a trap that involved three lasers that zapped waves of caesium atoms, making them move up and down like a fountain.

The waves were used as super-fast clocks, oscillating at nearly a million billion billion times per second.

The team's technique invoked a strange-but-true phenomenon of quantum mechanics: that an atom can be excited into two states at the same time.

In one of the states, the atom was "pushed" by laser pulse one tenth of a millimeter (0.004 of an inch), giving it a minute boost away from Earth's gravitational field. In the other, it remained unmoved.

More on the site, I just want to hear your opinons, on the mainstream side of science, and this article; thats is it, I am not trying to prove that GR is real

They are measuring clocks, with delightfully accurate clocks...

The flow of time is affected by gravity.

... switching between the use of the words "time" and "clocks" is often a handy trick with SR relativists.

But Sagnac in 1913, Michelson following the Michelson-Gale confirmation of the Sagnac effect for the rotating Earth in 1925 (not an independent experiment, so not listed in Table 1), and Ives in 1941, all claimed at the time they published that their results were experimental contradictions of Einstein SR because they implied a preferred frame.

Can't escape that preferred frame, which Sagnac experiment demonstrates.

Plenty on tpods about SR / GR.... search/browse much?
