Researchers use numerical simulations to show connection between Earth's changing shape and gravitational effects of other bodies in the Solar System. The study reveals that changes in the Earth's axial tilt can produce large changes in climate.
A study published in Science has re-examined the priority and plagiarism surrounding Einstein's General Relativity theory. The researchers argue that David Hilbert, not Einstein, was the first to submit the correct field equations of General Relativity, clearing Einstein of any wrongdoing.
Astronomers have detected the 'frame-dragging' effect, a prediction by Albert Einstein 80 years ago, in disks of gas swirling around black holes. The team used X-ray astronomy satellites to measure the precession of accretion disks, finding evidence of frame dragging in two black hole systems.
A gravity survey conducted in a Portland rail tunnel has helped identify previously unknown faults in the area. The survey revealed irregularities that suggest seismic activity, with data set to inform detailed maps of the subsurface.
A University of Illinois professor has modeled gravitomagnetic induction as the gravitational analog of Faraday induction in electromagnetism. The effect could influence a neutron star's spin, internal structure and orbital motion.
Research at Brandeis University reveals the human brain's ability to quickly adapt to changing gravitational forces. Directed motions such as pointing and walking speed are significantly affected by changes in gravity.
