## What is general theory of relativity?

The general theory of relativity (or general relativity for short) is a major building block of modern physics. It explains gravity based on the way space can ‘curve’, or, to put it more accurately, it associates the force of gravity with the changing geometry of space-time.

### What is the formula for the general theory of relativity?

One of the most famous and well-known equations in all of human history, E = mc^2, translates to “energy is equal to mass times the speed of light squared.” In other words, wrote PBS Nova, energy (E) and mass (m) are interchangeable. They are, in fact, just different forms of the same thing.

**Why Einstein equation is nonlinear?**

The nonlinearity of the Einstein field equations stems from the fact that masses affect the very geometry of the space in which they dwell. And this is the fundamental insight of (1): mass curves the geometry of spacetime, and the geometry of spacetime in turn tells masses how to move.

**Is general relativity a law or theory?**

General relativity is a theory of gravitation developed by Einstein in the years 1907–1915.

## Why is general relativity a theory?

General relativity is a theory of gravitation developed by Albert Einstein between 1907 and 1915. The theory of general relativity says that the observed gravitational effect between masses results from their warping of spacetime. In Newton’s model, gravity is the result of an attractive force between massive objects.

### How do you explain the theory of relativity?

The special theory of relativity was based on two main postulates: first, that the speed of light is constant for all observers; and second, that observers moving at constant speeds should be subject to the same physical laws. Following this logic, Einstein theorized that time must change according to the speed of a moving object relative…

**What is the formula for the theory of relativity?**

The General Theory of Relativity can actually be described using a very simple equation: R = GE (although Einstein’s own formulation of his field equations are much more complex).

**What are the theories of relativity?**

Theory of relativity. The theory of relativity was developed by Albert Einstein in the early 1900s. There are two theories of relativity. The first is special relativity and the second is general relativity. The theory aims to solve problems which could not be solved by classical physics, or by 19th century physics.

## What is the difference between general and special relativity?

Both General and Special Relativity have a lot in common, but they differ in some aspects. One of the major differences between the two types is that Special Relativity treats space and time the same way, contending that both things cannot be separated and are the same concepts. Special Relativity theory says that time and space are intertwined.
