"General relativity is likely incomplete for describing the very first moments of the universe, when quantum effects should ...
The $25 "Rise" plush, which reproduces the look of the moon mascot, includes many of the features of the flown-to-the-moon ...
Abstract: A MEMS acceleration latching switch has been developed through concept, analysis, design and prototype test in this paper. The switch has the sensitivity to both thresholds of acceleration ...
Cosmic viewer The Atacama Cosmology Telescope in Chile was used by the team to observe gravitational interactions between ...
Earth’s gravitational force, g, has been known for centuries. But the exact value of G, the universal gravitational constant, ...
Measuring the strength of gravity is extraordinarily difficult, and different experiments have always disagreed – but a new ...
The Large High Altitude Air Shower Observatory (LHAASO) has detected PeV (1015 eV) gamma-ray emission from a pulsar wind ...
By studying galaxy clusters separated by hundreds of millions of light-years, Penn physicist Patricio Gallardo and ...

Abstract: Objective: This paper proposes a wearable human motion tracking device using micro flow sensor incorporating a micro accelerometer, which allows detecting postures of human limbs in dynamic ...
Gravity has been tested extremely well inside the solar system. On cosmic scales, direct tests are harder. This study pushes ...
A NIST researcher has unveiled the results of a 10-year quest to measure the gravitatinal constant., which determines the strength of the attraction between two masses anywhere in the universe.
