Summary
Time is currently measured by radio waves, which together, tell us what time it is. But according to Ph.D. fellow Eliot Bohr, even atomic clocks could become more precise. This is because the detection laser used by most modern clocks heats up the atoms so much that they escape.
Atomic clocks are sensitive to gravitational changes and can therefore be used to detect changes in Earth's mass and gravity. This could help us predict when volcanic eruptions and earthquakes will occur. The research was conducted by the team of Jörg Helge Müller and Jan Thomsen at the Niels Bohr Institute.
