## What is the theory of special relativity in simple terms?

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. Simply put, as an object approaches the speed of light, its mass becomes infinite and it is unable to go any faster than light travels.

## Why is special relativity so hard?

Quantum mechanics and relativity both seem hard because they feature phenomena that are outside the everyday understanding we grow up with. But for relativity, it’s really just a matter of re-arranging the concepts we already have. In the case of quantum mechanics, the sticky step is the measurement process.

**How do you explain the theory of 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.

**How do you explain the theory of relativity to a child?**

1. The principle of relativity: The laws of physics are the same for any inertial reference frame. 2. The principle of the speed of light: The speed of light in a vacuum is the same for all observers, regardless of their relative motion or the motion of the source of the light.

### How did Einstein prove relativity?

Albert Einstein, in his theory of special relativity, determined that the laws of physics are the same for all non-accelerating observers, and he showed that the speed of light within a vacuum is the same no matter the speed at which an observer travels, according to Wired.

### How did Einstein figure out relativity?

General relativity predicted that light would bend in a gravitational field. In 1919, British expeditions to Africa and South America observed a total solar eclipse to see if the position of stars near the Sun had changed. The observed effect was exactly what Einstein had predicted.

**How did Einstein discover relativity?**

Einstein then wondered how light would behave in the accelerating room. In his four papers, published in November 1915, Einstein laid the foundation of the theory. In the third in particular he used general relativity to explain the precession of the perihelion of Mercury.

**Why is relativity still a theory?**

This theory is still considered to be the most important idea in modern physics. It rewrote Isaac Newton’s physical laws devised 200 years earlier and created an elegant way to understand the Universe.

#### Who gave the principle of relativity?

Albert Einstein’s

Albert Einstein’s theory of relativity is famous for predicting some really weird but true phenomena, like astronauts aging slower than people on Earth and solid objects changing their shapes at high speeds.

#### What does E mc2 mean in simple terms?

Energy equals mass times the speed

Einstein’s Big Idea homepage. 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.

**What did Einstein mean by time is relative?**

In the Special Theory of Relativity, Einstein determined that time is relativeâ€”in other words, the rate at which time passes depends on your frame of reference. The effect of time slowing down is negligible at speeds of everyday life, but it becomes very pronounced at speeds approaching that of light.

**How was E mc2 proven?**

An instrument called GAMS4, originally designed and built at NIST and now located at Institut Laue Langevin in France, was used in experiments that helped to confirm Einstein’s famous equation E=mc2;.

## What is the formula for special relativity?

E = mc 2. One of the results of the theory of special relativity is Einstein’s famous equation E = mc 2. In this formula E is energy, m is mass, and c is the constant speed of light.

## How do you explain relativity?

Einstein’s Theory of Relativity Explained (Infographic) The theories of relativity by Albert Einstein revolutionized how the world thinks about space, time, mass, energy and gravity. Prior to Einstein, the laws of Isaac Newton were used to understand the physics of motion. In 1687, Newton wrote that gravity affects everything in the universe.

**What are the theories of relativity?**

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.

**What is an example of general relativity?**

A central idea in general relativity is the “principle of equivalence.”. An example is that two people, one in an elevator sitting on the surface of the earth, and the other in an elevator in outer space accelerating at 9.8 m/s 2, will each observe the same behavior of an object they drop from their hand.
