# Question: What Is Theory Of Relativity In Simple Words?

## What did Einstein mean by time is relative?

In the Special Theory of Relativity, Einstein determined that time is relative–in other words, the rate at which time passes depends on your frame of reference.

The faster a clock moves, the slower time passes according to someone in a different frame of reference..

## What is the most famous equation ever written?

Einstein’s greatest equation, E = mc², is a triumph of the power and simplicity of fundamental physics. Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously.

## Why is C Squared?

Now we’re getting to the c² part of the equation, which serves the same purpose as the star-on and star-off machines in “The Sneetches.” The c stands for the speed of light, a universal constant, so the whole equation breaks down to this: Energy is equal to matter multiplied by the speed of light squared.

## How do we use E mc2 today?

They are metamorphosing mass into energy in direct accordance with Einstein’s equation. We take advantage of that realization today in many technologies. PET scans and similar diagnostics used in hospitals, for example, make use of E = mc2.

## What is the theory of relativity used for?

The theory explains the behavior of objects in space and time, and it can be used to predict everything from the existence of black holes, to light bending due to gravity, to the behavior of the planet Mercury in its orbit. The implications of Einstein’s most famous theory are profound.

## Is E mc2 proven?

Send this by. It’s taken more than a century, but Einstein’s celebrated formula e=mc2 has finally been corroborated, thanks to a heroic computational effort by French, German and Hungarian physicists. … The e=mc2 formula shows that mass can be converted into energy, and energy can be converted into mass.

## Is the theory of relativity fact?

Experimental evidence. Einstein stated that the theory of relativity belongs to a class of “principle-theories”. As such, it employs an analytic method, which means that the elements of this theory are not based on hypothesis but on empirical discovery.

## 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.

## Why is it called the theory of relativity?

Einstein’s theory gets its name because it describes how measurements of space and time differ for observers moving relative to one another. 3. … The theory gets its name from the relativity of motion, but the fact that motion is relative had already been known for centuries.

## What does E mc2 mean in simple terms?

E = mc2. It’s the world’s most famous equation, but what does it really mean? “Energy equals mass times the speed of light squared.” On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.

## How did Einstein prove relativity?

Gravity Probe B showed this to be correct. In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity.
