Is gravity a force or not?
gravity not as a force, but as the curvature of spacetime
How does mass tell spacetime how to curve?
Mass tells spacetime how to curve through its gravitational pull. According to Einstein's theory of general relativity, mass causes spacetime to bend or curve around it, creating the force of gravity. The more mass an object has, the stronger its gravitational pull and the greater the curvature of spacetime around it.
Is gravity a force acting on objects or a curvature of spacetime that influences their motion?
Gravity is a force that acts on objects, pulling them towards each other due to the curvature of spacetime caused by massive objects.
Which fundamental force is the result of warped spacetime?
Gravity is the fundamental force that is the result of warped spacetime, as described by Einstein's general theory of relativity. The presence of mass and energy warps the fabric of spacetime, causing objects to move in curved paths due to the force of gravity.
Why does mass warp spacetime?
Mass warps spacetime due to the presence of gravity. According to Einstein's theory of general relativity, mass causes spacetime to curve, creating what we perceive as the force of gravity. This warping of spacetime is what causes objects to be attracted to each other.
What is gravity if it is not a force?
Gravity really is one of the four main forces of the Universe. gravity is an effect and not the cause of anything, no gravitation's, no gravity waves, none of it. gravity is a dynamic effect. the acceleration of the underlying for of energy focused to the center of a mass. there is no separate force called gravity, just a dynamic effect we call 'gravity'
What is the reason behind gravitation?
Based on Einstein's theory of relativity, spacetime is curved around massive objects, and gravity "acting" on objects is actually just the objects following this curve in spacetime. Gravity is not a force.
What is gravity composed of?
Gravity is not a substance. It is not "made" of anything in that sense. It is an attractive force between objects with mass caused by a distortion of spacetime.
What are the key differences between Newtonian gravity and Einstein's theory of gravity?
Newtonian gravity is based on the concept of a force acting between two objects based on their masses and distance, while Einstein's theory of gravity, known as general relativity, describes gravity as the curvature of spacetime caused by mass and energy. In general relativity, gravity is not a force but rather a result of the geometry of spacetime.
What controls gravity?
Gravity is a natural force that exists between any two objects with mass. It is described by the theory of general relativity proposed by Albert Einstein, which posits that gravity is a result of the curvature of spacetime caused by mass and energy. In other words, gravity is not controlled by any external force or mechanism, but rather is an inherent property of mass and its interaction with spacetime.
When did albert Einstein discover gravity?
Albert Einstein did not discover gravity; rather, he developed the general theory of relativity in 1915, which revolutionized our understanding of gravity as a curvature of spacetime. This theory explains how massive objects like planets and stars warp the fabric of spacetime, causing the force of gravity.
Does gravity have an affect on photons?
Yes, photons are affected by gravity. Gravity can cause light to bend around massive objects like stars or galaxies, a phenomenon known as gravitational lensing. This effect has been observed and confirmed through astronomical observations.
