## What is Einstein theory of relativity – Albert Einstein relativity theory?

- The theory of relativity is actually two interrelated theories called “Special Theory of Relativity” & “General Theory of Relativity”.
- Special Relativity theory revolves around almost all physical marvels including time, speed of light and others. This theory was published in 1905.
- In Special Relativity theory, Einstein explained that it is possible for time to be different but the speed of light is always the same regardless of the place of the observer.
- General Relativity theory revolves around gravity and the curvature of space-time. In his theory he said falling mass in space-time can influence the surroundings.
- He called space-time fabric and showed that falling mass is causing a dimple in this fabric that means it bends. Further, he explained that due to this curve other masses around slip towards this matter.
- The importance of his theory increased over Newton’s theory because it explained Mercury’s Orbit.

## Albert Einstein’s Gravity Theory:

- According to Einstein’s concept of gravity, it is not described as force, in fact, it is just a consequence of an uneven distribution of mass on a wide fabric called space-time.
- Due to the curve created by the weight of falling mass on this fabric other matter slips towards it (explained in general theory). So we call it the attraction or ability of masses to free fall.

## Albert Einstein’s Quantum Theory – Albert Einstein Quantum Physics:

- Albert Einstein is known as the third founder of quantum theory. According to his point of view, quantum theory should be seen on an atomic level.
- He explained that light is in the form of small packets of energy called photons. Einstein called those small packets “quanta”.
- Hence, this theory states that metals emit electrons when light hits them which is known as the photoelectric effect.

## Albert Einstein Quantum Mechanics:

- Although Albert and Neil Bohar gave the foundation to “Quantum Mechanics” but Albert Einstein never supported it because he was against it.
- He always believed that everything is definite and quantum mechanics is quite uncertain hence he rejected it.
- The Quantum Mechanics he developed is considered as one of the two pillars of modern physics (the other is Relativity).

## Albert Einstein Black Hole Theory:

- Einstein was the first predictor of black holes with the help of his general theory (1915).
- Well, Albert denied the phenomena of black holes several times. Because he believed that a collapsing star would always twirl faster and faster before collapsing into a singularity (explained in a published paper by Albert in 1939).

## Albert Einstein Time Theory:

- As a sheer genius Albert always came up with a unique point of view about almost everything in physics —so in the “Theory of time”.
- In the theory of time, he explained that time is an “illusion” and it varies from place to place, depending upon a person’s location.
- His theory of special relativity explains that the time of a person could be slower in a spaceship that is flying at the speed of light (299, 792 458 m/s) than the time for his twin on Earth.
- Now to observe time between both twins, calculate their age.
- You will see a clear difference in their age and that is because of time dilation of Space.
- As explained earlier, time variation depends upon the person’s location.
- Hence it is proved that time is not constant. In space, it runs so slow that you might think that time has stopped.
- On the other hand, time on Earth is fast enough that the person coming from space would be much younger than his twin on Earth.

## Albert Einstein and Time Travel:

- According to Einstein theories, time travelling is just an illusion. Because in his point of view “time” itself is an illusion.
- Time travelling in this case could only be possible if a person in space is moving at the speed of light.
- Else he proved that none could be faster than the speed of light hence anything moving at the speed of light will definitely have an impact on time.

## Time quote Albert Einstein:

“Time and space are modes by which we think and not conditions in which we live.”
