Einstein's theory of gravity predicts that a rotating body, such as Earth, partially drags inertial frames along with its rotation. Scientists suggest a novel approach to measuring what is referred to ...

March 14 (UPI) --Scientists are preparing to measure the inertial rotation of Earth using an underground laser-based gyroscope. The goal is to reveal fluctuations in Earth's rate of rotation and ...

Laser gyroscopes represent a pivotal technology in measuring Earth’s rotation with unmatched precision, utilising the Sagnac effect to detect minuscule angular variations. These instruments, often ...

All in a spin: Two indistinguishable photons (red lines) are incident on a beamsplitter cube and become entangled. The two photons are then coupled into an optical fibre-based interferometer, which is ...
