Newton's Gravity Einstein's Gravity Gravitational Waves and Other Theories Gravity in Our Solar System Gravity: Did You Know? Unraveling the Mystery Newton set forth the idea that gravity was a predictable force. His cumulative work earned him a monument at the Griffith Observatory (that's astron...
Einstein's theory was quickly accepted as the true theory of gravity after its publication in 1915, but soon took a back seat in physics to quantum mechanics and languished for decades on the blackboards of mathematicians. Not until the existence of black holes by Stephen Hawking and Roger ...
When did life start on Earth and how do they know? Life on Earth is believed to have originated around 3.5 billion years ago, as evidenced by the discovery of microfossils and biomarkers in some of the oldest rocks on the planet. These rocks, found in places like Western Australia, provide...
Explain needed so basically using gravity to push things up? How would you reverse the energy?. What did Einstein suggest about gravity through his theory of relativity? Explain in detail about the scattering of light with examples? What would happen to us if the gravity is a bit stronger ...
How did scientific knowledge change because of Einstein's theories? How is a philosophical idea different from a scientific theory? What is the difference between a guess and a scientific theory? What scientists developed atomic theories? Who made the scientific method?
What would happen if Earth stopped spinning? There is no chance that you'll be flung off to space right now, because the Earth's gravity is so strong compared to its spinning motion. (This latter motion is called centripetal acceleration.) At its strongest point, which is at the equator,...

Interestingly, Albert Einstein predicted the existence of dark energy back in 1917 as he tried to balance the equations of his general theory of relativity. He didn't call it dark energy at the time. He referred to it as thecosmological constantand labeled it lambda in his calculations. Altho...
— Einstein's theory of general relativity — The Big Bang: What really happened at our universe's birth? — How does time work? In the case of loop quantum gravity, the singularity is replaced with a finite-size chunk of space-time. Instring theory, meanwhile, our uni...
Einstein did not suggest E=MC2 and then performed the work to prove it. He did the work and that led to the equation. Same with general and special relativity. Best not to jump directly to pure conjectures such as DIMP. Based on data gained so far, the idea that arou...
