Resembling a squat, wide fridge, the world's most accurate clock went on sale for $3.3 million in Japan on Wednesday.

Known as a "strontium optical lattice clock," it is 100 times more accurate than caesium atomic clocks, the current standard for defining seconds, the precision-equipment producer said in a statement.

“The challenge lies in the fact that GR corrections in most tabletop experiments are minuscule, making them extremely difficult to detect. However, atomic clocks are now reaching unprecedented ...
