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 ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

Mystery of the Antarctica 'gravity hole' finally cracked by scientists
Antarctica sits above the strongest negative gravity anomaly on Earth, a region where the planet’s gravitational pull dips so low that the sea surface sags by more than 100 meters compared to the ...

Is gravity itself the missing piece in the dark matter mystery?
About 85 percent of the matter in the universe is thought to be dark matter, yet there is still no confirmed direct detection of any dark matter particle. Ground-based detectors, space-based ...
