Did Einstein said gravity is not a force?
Einstein argued that gravity isn’t a force at all. He described it as a curvature of time and space caused by mass and energy. Their math, laid down in 10 equations, explained how gravity could move around objects via a warped reality, accelerating without ever feeling any mysterious Newtonian forces.
Do forces exist according to Einstein?
He considered gravity to be a force that objects exert upon each other. But, in a burst of brilliance, Einstein realized that no such force is required and in fact no such force exists. Based on this thought experiment, Einstein concluded that gravity is not a force of attraction, for no such force is required.
What did Einstein discover about gravity?
Einstein did. He theorized that a mass can prod space plenty. It can warp it, bend it, push it, or pull it. Gravity was just a natural outcome of a mass’s existence in space (Einstein had, with his 1905 Special Theory of Relativity, added time as a fourth dimension to space, calling the result space-time.
What creates gravitational pull?
The answer is gravity: an invisible force that pulls objects toward each other. So, the closer objects are to each other, the stronger their gravitational pull is. Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.
Is gravitational pull and gravitational force the same thing?
Gravity or gravitational forces are forces of attraction. That pull is gravity at work. Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects.
What did Einstein say about gravity?
Einstein argued that gravity isn’t a force at all. He described it as a curvature of time and space caused by mass and energy.
Can Einstein explain black holes but not gravity?
New research confirms Einstein’s theory of gravity but brings scientists a step closer to the day when it might be supplanted by something new. An artist’s rendering of a supermassive black hole. NASA/JPL-Caltech Albert Einstein can explain a lot, but maybe not black holes.
What are the main takeaways behind Einstein’s general theory of relativity?
The main takeaways behind Einstein’s general theory of relativity: 1 Time and space are neither flat nor fixed; they are curved and distorted by mass and energy. 2 Gravity is not a force, but rather a distortion of time and space. 3 The effects of gravity are indistinguishable from the effects of acceleration, over a small space.

Is gravity a force or not?
Einstein argued that gravity isn’t a force at all. He described it as a curvature of time and space caused by mass and energy. Confused? The German physicist was, too, and he struggled with the theory for nearly a decade.
