What is Einstein theory of gravity?

Summary. According to the theory of general relativity, gravity is the result of distortions in space-time created by mass and energy. The principle of equivalence states that that both mass and acceleration distort space-time and are indistinguishable in comparable circumstances.

What is the theory of gravity in simple terms?

Isaac Newton was the first to develop a quantitative theory of gravity, holding that the force of attraction between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them.

What is the Einstein gravity equation?

In Einstein's theory of gravity, this constraint is given by the Einstein gravitational field equations. These field equations were first introduced by Albert Einstein in 1915 after almost ten years of struggle. (1.15) G = κ T . κ = 8 π G / c 4 .

How is Einstein's theory of gravity different from Newton's?

To summarize the two views of gravity, Newton envisioned gravity as a tug of war along the line connecting any two objects in the universe. In contrast, Einstein envisioned gravity as a bending of space-time by mass.

Does gravity bend space according to Einstein?

Gravity as Curved Spacetime

Einstein eventually identified the property of spacetime which is responsible for gravity as its curvature. Space and time in Einstein's universe are no longer flat (as implicitly assumed by Newton) but can pushed and pulled, stretched and warped by matter.

Einstein's Gravity

Is gravity a force or an illusion?

However, in the broader sense, gravity is indeed a force because it describes the resulting interaction between two masses. Gravitational effects are fundamentally caused by the warping of spacetime and the motion of objects through the warped spacetime. However, the end result is as if a force was applied.

How does gravity bend light if it has no mass?

While it is true that photons have no mass, it is also true that we see light bend around sources with high mass due to gravity. This is not because the mass pulls on the photons directly, but instead because the mass warps the space-time through which the photons travel. Imagine a bowling ball on a mattress.

Why is Einstein's theory of gravity accepted today?

Einstein showed mathematically that gravity is not really a force of attraction between all objects with mass, as Newton thought. Instead, gravity is a result of the warping of space-time. Einstein's ideas have been supported by evidence and are widely accepted today.

Why is gravity not a force according to Einstein?

Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915), which describes gravity not as a force, but as the curvature of spacetime, caused by the uneven distribution of mass, and causing masses to move along geodesic lines.

What is the IQ of Einstein Newton?

The Man had an IQ of 260, which surpassed the IQ level of Isaac Newton, which was 190 and Albert Einstein of 160. The boy was called the child prodigy and made the headlines of the New York Times in the 20th century. Born in 1898 in Boston, the boy could read newspapers at the age of 2.

Does Einstein believe in God?

Religious beliefs. Albert Einstein himself stated "I'm not an atheist, and I don't think I can call myself a pantheist ... I believe in Spinoza's God who reveals himself in the orderly harmony of what exists, not in a God who concerns himself with fates and actions of human beings".

Who proved E=mc2 is wrong?

Remembering ECG Sudarshan, The Indian Who Proved Einstein Wrong | The Kerala-born physicist was nominated for the Nobel prize nine times. By InUthFacebook.

How did Einstein prove his theory of gravity?

Einstein postulated three ways this theory could be proved. One was by observing the stars during a total solar eclipse. The sun is our closest strong gravitational field. Light traveling from a star through space and passing the sun's field would be bent, if Einstein's theory were true.

Is gravity a law or theory?

Isaac Newton's 1687 description of gravity was considered scientific law until Einstein's General Theory of Relativity, published more than two centuries later. Newton had explained gravity as a force that instantaneously acts over a distance. The result is a pull between any two objects in the universe.

Is the theory of gravity correct?

This theory is highly accurate in its predictions regarding everyday phenomena. However, high precision measurements of motions in the solar system and in binary pulsars, the structure of black holes, and the expansion of the universe can only be fully understood in terms of a relativistic theory of gravitation.

Is gravity a theory or a fact?

So, is gravity a theory or a law? Well, first of all, it is an always acting force that one can feel. Second, it is both a theory and a law. The law of gravity calculates the amount of attraction while the theory describes why objects attract each other in the first place.

What did Einstein say about the force of gravity?

The universe is bigger than we ever imagined, and getting bigger all the time, while what we think of as matter is mostly empty space.

How much would a 100lb person weigh on Jupiter?

For example, if you weigh 100 pounds on Earth, you would weigh only 38 pounds on Mercury. That's because Mercury weighs less than Earth, and therefore its gravity would pull less on your body. If, on the other hand, you were on heavy Jupiter, you would weigh a whopping 253 pounds!

What is Albert Einstein's theory?

Special relativity is an explanation of how speed affects mass, time and space. The theory includes a way for the speed of light to define the relationship between energy and matter — small amounts of mass (m) can be interchangeable with enormous amounts of energy (E), as defined by the classic equation E = mc^2.

How did Einstein predict black holes?

Black holes are regions of spacetime where gravity's pull is so strong that nothing, not even light, can escape from being dragged in and "eaten." Einstein's theory of general relativity predicted the existence of black holes and that, no matter what such an object "eats," black holes are characterized only by their ...

Where does gravity come from?

Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That's what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.

What was the problem with Newton's theory of gravity?

Newton's theory of universal gravity was attacked from 1687 by some of Europe's leading intellectuals, including Huygens and Leibniz, because it rigorously excluded any hypothetical mechanism, and implied that forces could be transmitted between material particles across empty space.

How can a black hole be massive but not big?

Except… there's one kind of black hole that isn't quite the size astronomers believe it should be. They're ostensibly regular supermassive black holes, but they “live” in galaxies that seem far too young to host such massive gravity wells. Usually, supermassive black holes form over the course of billions of years.

Does gravity affect time?

Albert Einstein's theory of general relativity predicts that where gravity is stronger, time passes more slowly. That's called time dilation. Gravity is stronger closer to the center of the Earth.

Is lightning affected by gravity?

Gravity accelerates energy and mass. Electrons are energy and contain mass. But since lightning would have such negligible mass from electrons gravity would have little to no effect on its electrons.
