Here’s what you’ll learn when you read this story: Einstein’s Theory of General Relativity, an immensely important update to Newton's Law of Universal Gravitation, is currently our best approximation ...

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 ...

The cosmos is a unique laboratory for testing the laws of physics, in particular those of Euler and Einstein. Euler described the movements of celestial objects, while Einstein described the way in ...

Einstein’s theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own ...

In a recent development, an innovative study has uncovered compelling evidence supporting a revised theory of gravity, particularly under conditions of low acceleration. This study signifies a notable ...

Everything in the universe has gravity – and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein’s theory ...

Here’s what you’ll learn when you read this story: In 1687, English physicist Isaac Newton published his famous Law of Universal Gravitation. The idea that all objects attract in proportion to their ...

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.
