The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make up nearly 70% of the cosmos, has been the leading explanation. But a new ...
Although we take a lot of scientific knowledge for granted today, each of the basics – whether it be about light, gravity, mass or the shape of the Earth – had to be theorized and experimentally ...
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 ...
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 ...

Living without gravity spells disaster for the human body. Even a few weeks in microgravity can lead to issues with circulation and vision; over the longer term, the complications compound even ...

Why the sun doesn’t drift away: gravity and orbital balance explained
The Sun is not nailed to the center of the solar system. It moves, wobbles, and traces a small loop through space, tugged by ...
