Albert Einstein held that space and time together made up the universe's fabric that could stretch and compress. Einstein suggested that the shape of spacetime is what gives rise to the force of gravity. A concentration of mass, like the earth or sun, bends space around it, like water that bends around the flow of a river. When other objects move closeby, they follow the curvature.
Einstein's field equations of general relativity, which show how matter and energy warp spacetime, gained acceptance when they successfully predicted the changes in Mercury's orbit.

While Isaac Newton's description of gravity was good enough to detect Neptune's existence in the mid-1800s, Newton's law was not perfect. Astronomers discovered a mismatch between his law and the laws of nature.
This mismatch was resolved in 1915 when Albert Einstein published his theory o...

In 1687, Isaac Newton's treatise Philosophiæ Naturalis Principia Mathematica showed that every object in the universe, small and great, pulled on every other object, from a grain of sand to the planets.
Newton could compute the attraction: Doubling the mass of one object makes it...

The current description of gravity is so accurate that it has become a guide for cosmic discoveries.
American astronomers noticed in the 1960s that galaxies appear to rotate fast enough to spin-off stars. However, they did not whirl apart, and something seems to help them stick together. M...

Einstein's special theory of relativity applies only to steady, unchanging motion through space-time, not accelerating motion like an object falling toward Earth.
Albert Einstein did not think about symmetry when he wrote his first relativity papers in 1905. He was considering several seemingly unrelated puzzles and connecting the dots.
According to physicists, quantum particles are responsible for three forces of nature:

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!
