You see this all the time in textbooks: This is often described as "the acceleration due to gravity". Is this really the best thing to call this? No. A better name would be "the local gravitational ...

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 ...

Caltech engineer Mory Gharib was poring over the digitized notebooks of Leonardo da Vinci one day, looking for sketches of flow visualization to share with his graduate students for inspiration.

One of the most astonishing facts about science is how universally applicable the laws of nature are. Every particle obeys the same rules, experiences the same forces, and sees the same fundamental ...

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 - ...

Long after the human race has vanished or evolved into something else, long after the sun has swollen into a red giant and incinerated Earth 5 billion years from now, at least one human artifact will ...

You may have heard people say that aboard the International Space Station (ISS) there's "zero gravity," but in fact, gravity is still very much present. The station orbits Earth at an altitude of ...

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 ...
