1905 - Theory of Relativity by Albert Einstein

History Nov 2, 2020

We all know Albert Einstein but we don’t know the story behind the successor. Let the know-how einstein found Theory of Relativity.

Born in Ulm, a small village in Germany, he was a dull-minded child, All the efforts of the school teacher for a bright future for this chield are failed. One teacher even gave a verbal certificate in advance saying, ‘Nothing can happen in your life!’ but the teacher doesn’t know which child becomes a super minded person in the future.

Years later, after passing a diploma course from the Polytechnic Institute of Switzerland, Einstein took a job as a third-rate technical assistant in the patent office. His main job was to verify the claims of ingenious researchers who came to file patents for new inventions.

Albert’s mind was so engrossed in various inventions and theories that he soon became like a magic lamp. It was from that mind that the theory of relativity finally emerged in 1908.

In earlier times, however, according to the theory established by Isaac Newton, scientists believed that

the speed of light increases and decreases according to the speed of its origin
the whole structure of the universe is as stable as a lake. It can measure the independent velocity of objects (or spheres) floating like fish.

Theory of Relativity by Albert Einstein

The 26-year-old Einstein, however, completely shattered the 200-year-old Newton’s theories about the creation of the universe! In 1904, in his Special Theory of Relativity, Einstein established that

the speed of light is always the same. It has nothing to do with the speed of origin.
Nothing is static in the universe. Since the planets, stars, and nebulae are all in constant motion, it is not possible to measure the absolute motion of any object. The exact motion of each can only be measured with respect to another object.

The speed of a moving object depends on the place in which its motion is measured. For example, the speed of train A running at a speed of 80 kilometers per hour while standing on the platform seems to be 80 kilometers.

But if you drive another train B at a speed of 60 km/h next to the same train, then the speed of train A will be only 20 km/h instead of 80 km/h! On the other hand, the passenger sitting in train A running at a speed of 80 km/h seems to be retreating by train B!

If the speed of the object is not relative then the speed of train A should feel the same for the passenger standing on the railway platform and the passenger sitting in another train running parallel. Of course, that doesn’t happen.

In addition to motion, Einstein also considered space and time to be relative, with time relativity being the most astonishing aspect of the Special Theory of Relativity. Newton and later scientists believed that the speed of time was the same on Earth as well as in the universe billions of kilometers away from the Earth.

The explanation according to Einstein

But according to Einstein, the speed of time is not the same everywhere. Time does not exist in the black hole of the universe where time becomes stagnant! Earth clocks and calendars become useless in space after leaving Earth. To simplify the intricacies of time relativity in space, Einstein gave a hypothetical example:

Two twin brothers, Neil and Bill, embark on a space flight at the speed of Neil Prakash (3 lakh kilometers per second). Twin brother Bill lives on earth. Neil is to return to Earth after covering a total distance of 6 light-years. (One light-year is the distance covered by a ray of light in a year i.e. 94,60,52,84,05,00 kilometers.) Normally the Neil spacecraft should take 24 light-years to cover 24 years.

According to Einstein’s theory of relativity, the speed of matter increases as time goes on, and when the speed of matter increases to the level of light, then time almost stops!

Since the speed of Neil’s spacecraft is almost the same as the speed of light, according to relativity, time flows at a very slow speed in his honor. As a result, Neil’s life span is barely a few days longer, with a gap of 24 light-years in space. On the other hand, it is equally true that 24 years have passed in the life of his twin brother Bill on earth!

Is. In 1905, Dr. Albert Einstein’s intricate (yet true) theory explaining the relativity of time was scrambled for years by hooked physicists around the world to prove it wrong. and yet that theory was going to prove to be accurate in everything years later!
