What is an example of special relativity?

If the speed of light is always the same, it means that an astronaut going very fast relative to the Earth will measure the seconds ticking by slower than an Earthbound observer will — time essentially slows down for the astronaut, a phenomenon called time dilation.

What are the two principles of Einstein special theory of relativity?

Einstein consistently based the derivation of Lorentz invariance (the essential core of special relativity) on just the two basic principles of relativity and light-speed invariance.

What does the theory of special relativity say?

In a nutshell, the Special Theory of Relativity tells us that a moving object measures shorter in its direction of motion as its velocity increases until, at the speed of light, it disappears. It also tells us that moving clocks run more slowly as their velocity increases until, at the speed of light, they stop running altogether.

What is the theory of relativity in a nutshell?

The theory of special relativity in a nutshell. Einstein’s Theory of Special Relativity, first postulated in 1905, says that the laws of physics and the speed of light are the same for all observers, regardless of their own speed or motion.

How did the theory of relativity change the world?

The equation and discovery of the Theory of Relativity changed countries, the world and the science community. The ways Relativity changed the world were due to the fact that before the Theory of Relativity, the world believed in so much other different ways such as Newtonian gravity. The theory of Relativity helped us learn about the speed of light and curved space.

What does theory of relativity stand for?

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.
