What does the theory of general relativity explain?
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.
What did the theory of general relativity predict?
General relativity predicts that the path of light will follow the curvature of spacetime as it passes near a star. This effect was initially confirmed by observing the light of stars or distant quasars being deflected as it passes the Sun.
Who is the formulator of the theory of relativity?
General relativity is physicist Albert Einstein’s understanding of how gravity affects the fabric of space-time. The theory, which Einstein published in 1915, expanded the theory of special relativity that he had published 10 years earlier.
Who introduced the theory of relativity in 1916?
Albert Einstein
Einstein’s General Theory of Relativity was published on May 11th, 1916. The greatest name in physics since Isaac Newton devised two theories of relativity, the special theory and the general theory. Albert Einstein was born at Ulm in Germany in 1879 to a Jewish family, who soon moved to Munich.
What is the main concern of theory of general relativity?
General relativity is concerned with gravity, one of the fundamental forces in the universe. Gravity defines macroscopic behaviour, and so general relativity describes large-scale physical phenomena.
What are three major predictions of the general theory of relativity?
Albert Einstein proposed three tests of general relativity, subsequently called the “classical tests” of general relativity, in 1916: the perihelion precession of Mercury’s orbit. the deflection of light by the Sun. the gravitational redshift of light.
What is the problem with general relativity today?
All masses and all sources of energy contribute to the curvature of spacetime, but we can only calculate the Earth-Sun orbit approximately, not exactly. This problem — the two-body problem in General Relativity — cannot be solved exactly.
What are the two main principles of general relativity?
The first postulate is the relativity principle: local physics is governed by the theory of special relativity. The second postulate is the equivalence principle: there is no way for an observer to distinguish locally between gravity and acceleration.
What are the three laws of relativity?
These three laws are: Objects in motion or at rest remain in the same state unless an external force imposes change. This is also known as the concept of inertia. The force acting on an object is equal to the mass of the object multiplied by its acceleration.
