What is the main idea of general relativity?

What is general relativity? Essentially, it's a theory of gravity. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.Apr 13, 2018

What is the main idea of general relativity quizlet?

General relativity tells us that gravity arises from the curvature of spacetime and that the curvature arises from the presence of masses. This idea leads us to a view of gravity in which time runs more slowly in gravitational fields, black holes can exist in spacetime, and the universe has no center or edges.

What are the main conclusions of general relativity?

The laws of physics apply equally to all frames of reference. The speed of light is constant in all frames of reference. There is no simultaneity of events between separate frames of reference. You are never too old to learn.

What is general relativity simple definition?

General relativity is a theory of space and time. The theory was published by Albert Einstein in 1915. The central idea of general relativity is that space and time are two aspects of spacetime. Spacetime is curved when there is matter, energy, and momentum resulting in what we perceive as gravity.

Why is a black hole black?

A black hole is a region of spacetime where gravity is so strong that nothing — no particles or even electromagnetic radiation such as light — can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

What does General Relativity say about gravity?

GETTING A GRIP ON GRAVITY Einstein's general theory of relativity explains gravity as a distortion of space (or more precisely, spacetime) caused by the presence of matter or energy. A massive object generates a gravitational field by warping the geometry of the surrounding spacetime.

Why is general relativity so important?

General relativity has developed into an essential tool in modern astrophysics. It provides the foundation for the current understanding of black holes, regions of space where the gravitational effect is strong enough that even light cannot escape.

Why is Einstein’s theory of general relativity important?

Formulated by Albert Einstein beginning in 1905, the theory of relativity explains the behavior of objects in space and time, and it can be used to predict things such as the existence of black holes, light bending due to gravity and the behavior of planets in their orbits.

Why is it called general relativity?

The general theory gets its name because it also includes gravity, which means it applies to a wider set of circumstances (which scientists call a more “general” set) than the special theory.

How does general relativity explain gravity?

GETTING A GRIP ON GRAVITY Einstein's general theory of relativity explains gravity as a distortion of space (or more precisely, spacetime) caused by the presence of matter or energy. A massive object generates a gravitational field by warping the geometry of the surrounding spacetime.
