Is E mc2 the theory of relativity?
Is E mc2 the theory of relativity?
Einstein's equation E = mc2 shows that energy and mass are interchangeable. The theory of special relativity explains how space and time are linked for objects that are moving at a consistent speed in a straight line. One of its most famous aspects concerns objects moving at the speed of light.
What is the main idea of general relativity?
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 gravity, matter, energy, and momentum. The links between these forces are shown in the Einstein field equations.
What is the formula for the general theory of relativity?
Who proved general theory of relativity?
General relativity (GR) is a theory of gravitation that was developed by Albert Einstein between 1907 and 1915, with contributions by many others after 1915.
How many theories of relativity are there?
The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity. Special relativity applies to all physical phenomena in the absence of gravity.
What was Albert Einstein’s theory of relativity?
The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity. Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its relation to other forces of nature.
How did Einstein develop the theory of relativity?
Since Einstein believed that the laws of physics were local, described by local fields, he concluded from this that spacetime could be locally curved. This led him to study Riemannian geometry, and to formulate general relativity in this language.
What is difference between special and general theory of relativity?
What is spacetime in layman’s terms?
Spacetime is simply the idea of time being a fourth dimension of space, so that you can locate events in time and space with a single system of coordinates. I.e. you locate an event in coordinates of length, width, height and time.
How did Einstein predict black holes?
The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon.
