Our understanding of the universe may be completely wrong.

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an ...

Astronomers have attempted to explain the non-gravitational acceleration of comet 3I/ATLAS, our third confirmed interstellar visitor, in a way that removes the need for "non-natural hypotheses for ...

The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make ...

Dr. Sukanya Chakrabarti, the Pei-Ling Chan Endowed Chair in the College of Science at The University of Alabama in Huntsville (UAH), and her team have pioneered the use of gravitational acceleration ...

Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...

The Qatar General Organisation for Standards and Metrology (QGOSM) announced the completion of the first measurement of absolute gravitational acceleration in Qatar. This measurement was taken as part ...

In a recent study published in Scientific Reports, researchers explored how nutrition knowledge, physical strength and activity, and body composition are related to whether Air Force cadets lose ...
