What is the theory of relativity for dummies?

The theory of relativity was revolutionary because it showed how the speed at which time happens is mutable; that space and time are not discrete entities: time and space and motion (ie, movement through space) collapse into a fourth dimension, in which all act on each other.

What is a simple example of relativity?

One example of relativity is to imagine two people on a train playing ping-pong. The train is traveling at around 30 m/s north. When the ball is hit back and forth between the two players, the ball appears to the players to move north at a speed of around 2 m/s and then south at the speed of 2 m/s.

What does E mc2 mean in layman?s terms?

Energy equals mass times

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.

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.

What is E mc2 used for?

The equation ? E = mc2 ? means ?energy equals mass times the speed of light squared.? It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing. If mass is somehow totally converted into energy, it also shows how much energy would reside inside that mass: quite a lot.

Is General Theory of Relativity proven?

Relativity is a falsifiable theory: It makes predictions that can be tested by experiment. The predictions of special relativity have been confirmed in numerous tests since Einstein published his paper in 1905, but three experiments conducted between 1881 and 1938 were critical to its validation.

When did Albert Einstein come up with the general theory of relativity?

History of general relativity. Albert Einstein settled on his ?general? theory in 1915, a decade after he came up with a ?special? theory of relativity that applied a universal speed of light to the assumption that the laws of physics stay the same inside any given frame of reference. When Einstein tried to apply accelerating masses ?

Which is the oldest model of the theory of relativity?

Classical physics, also called Newtonian physics after 17th century physicist Isaac Newton, is the oldest model and the one that applies best to everyday human experiences. Classical physics describes the laws of motion and the mechanics of gravitational bodies.

How is time dilation explained by the theory of relativity?

Time dilation due to due to gravity can be given as: Here To is the time measured in the gravitational field & T is the time measured far away from the gravitational field. The above equation shows that greater is the mass of a body, more is the slowing down of time.
