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 ...

A new study reports conclusive evidence for the breakdown of standard gravity in the low acceleration limit from a verifiable analysis of the orbital motions of long-period, widely separated, binary ...

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

The first reports of comet 3I/ATLAS were made on July 1, 2025, by the ATLAS (Asteroid Terrestrial-impact Last Alert System) telescope in Chile. This comet caught the world's attention since it was the ...

A new look at da Vinci's papers reveals his insightful attempts to probe the nature of gravity 500 years ago. Engineers from Caltech have discovered that Leonardo da Vinci's understanding of gravity - ...

Ever since Newton published his universal law of gravitation in 1687, anyone with a slide rule and a half decent education could calculate the force of gravity on a falling body or a planet in orbit.

Engineers from Caltech have discovered that Leonardo da Vinci’s understanding of gravity—though not wholly accurate—was centuries ahead of his time. In an article published in the journal Leonardo, ...
