The interstellar comet 3I/ATLAS has been confounding scientists since it began unexpectedly accelerating, but the cause ...

Astronomers have attempted to explain the non-gravitational acceleration of comet 3I/ATLAS, our third confirmed interstellar ...

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 ...

Researchers analyze interstellar object 3I/ATLAS near the Sun to detect gravitational lensing, using ALMA and solar observatories, examining trajectory, non-gravitational acceleration and perihelion ...

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 ...

An illustration of an accelerating space rocket in Tom Siegfried’s essay “Getting a grip on gravity” (SN: 10/17/15, p. 16), explained that a clock at the top of the ship would tick faster than one at ...

The triangle ain't equilateral. Also, I read the jar drawing as being constant speed, not constant acceleration. Each consecutive falling object is at a constant horizontal distance. At the small ...
