Gravity measured for the first time using a portable ‘atomic clock’
Scientists have used a portable “atomic clock” to measure gravity for the first time. The device makes use of small changes in the flow of time at different altitudes to measure the Earth’s gravity. Generally speaking, atomic clocks are complex, delicate pieces of scientific equipment that are confined to labs and therefore cannot be used to make measurements in the field.
