a geometric theory of gravitation put forward by Einstein in 1916

(The general theory of relativity is a geometric theory of gravitation put forward by Einstein in 1916.

General relativity , also known as the general theory of relativity

General relativity, also known as the general theory of relativity, is the geometric theory of gravitation published by Albert Einstein in 1915 and the current description of gravitation in modern physics.

Einstein's theory of gravity

Just over 100 years ago, Einstein introduced Einstein's theory of gravity, known as general relativity.

the fundamental theory of gravity

General theory of relativity is the fundamental theory of gravity.

the force of gravity

The general theory of relativity describes the force of gravity.

one of the two pillars of modern physics

Albert Einstein developed the general theory of relativity, one of the two pillars of modern physics.

a unified theory of space, time and gravitation

General Relativity is a theory proposed by Einstein in 1915 as a unified theory of space, time and gravitation.

our current theory of gravity

The general theory of relativity is our current theory of gravity, and gravity perfectly describes the motions of both planets and galaxies.

Albert Einstein's theory of gravity, which describes gravitational forces in terms of the curvature of spacetime caused by the presence of mass

The general theory of relativity is Albert Einstein's theory of gravity, which describes gravitational forces in terms of the curvature of spacetime caused by the presence of mass.

an extension of special relativity

The General Theory of Relativity is an extension of special relativity, dealing with curved coordinate systems, accelerating frames of reference, curvilinear motion, and curvature of spacetime itself.

within the framework of classical physics

The general theory of relativity is formulated within the framework of classical physics, whereas the other fundamental forces are described within the framework of quantum mechanics.

the properties of gravity

General Theory of Relativity describes the properties of gravity and assumes that space is a smooth, continuous fabric.

use of the Einstein field equations

Technically, general relativity is a theory of gravitation whose defining feature is whose defining feature's use of the Einstein field equations.

the force of gravity and the large-scale structure of the universe,

The general theory of relativity describes the force of gravity and the large-scale structure of the universe,

and thus the world at large, quantum physics

For almost a century, the two major theories of physics have coexisted but have been irreconcilable: while Einstein’s General Theory of Relativity describes gravity and thus the world at large, quantum physics describes the world of atoms and elementary particles.

this vision , known as the general theory of relativity

The equations describing this vision, known as the general theory of relativity, have since become a cornerstone of modern physics—opening new doors for understanding everything from how planets and stars move to existence of dark matter and the early days of the universe itself.

Einstein's masterpiece, the general theory of relativity-a geometric theory of gravity

Without it Einstein could not have formulated Einstein's masterpiece, the general theory of relativity-a geometric theory of gravity (see Inside Science No.31).

gravity as a phenomenon created when matter warps the geometry of space and time

General relativity was first described in 1915 and it explained gravity as a phenomenon created when matter warps the geometry of space and time.

Einstein's re-working of Newton’s theory of gravity, which had been around for over two hundred years and which most physicists felt was as correct a theory as any that had been developed

General Theory of Relativity is Einstein's re-working of Newton’s theory of gravity, which had been around for over two hundred years and which most physicists felt was as correct a theory as any that had been developed.

a way to describe gravity

At its most basic, general relativity is a way to describe gravity by attributing gravity to the curvature of space-time that occurs in the presence of massive bodies.
