Albert Einstein's Theory Of Relativity: How It Can Be Related To Reality?

in science •  7 years ago 

The 'Relativity Theory', which is predicted by Albert Einstein, is seen as a beautiful and refined principle in the world of scientific thinking. Now this theory has become the basis pillar of physics. The modern physics of this theory is helpless in the same way, as the molecules-atoms of concepts. Working as a clerk at the patent office, Einstein wondered why he worked on the broad theory of theoretical physics. Since 1901, Einstein published his work each year in the German magazine 'Yearbook Book of Physics' . The interesting fact is that Einstein did not have much knowledge of contemporary science literature at that time.

In 1905 when Einstein was only 26 years old, he published four research papers, which laid the foundations of quantum mechanics and relativity theory. These were the same research papers that shook the theoretical physics. One of those papers was very long. The name of that research paper was 'On the Electrodynamics of moving bodies'. This is the research paper, which changed the scientific concept of human beings. In fact it was a description of the special theory of relativity. This theory of Einstein brought revolutionary change in traditional perceptions related to our times. In this, the dynamic observers / objects have been discussed in a straight line at the same speed. The special relativity theory is based on the following two postulates:

1. Our daily experience shows us that the speed of things in a straight and uniform velocity car does not differ at the speed of things in a steady vehicle. Therefore, the motion of the object in all the laboratories running relative and uniform motion relative to each other follows the same rules of physics. It is also called the relativity of motion.
2. Under this hypothesis, Einstein believed that the speed of light is always constant and that the speed of the source or the observer has no effect on it.

Many far-reaching findings of special relativity theory came out, which deeply influenced human thought. The major conclusions and effects of this theory are: Time Dilation, length-contraction, change of mass along with velocity etc. Since Einstein presented the extensive theoretical frameworks of physics in the year 1905, this year it is known in physics as the 'miraculous year'.

The special relativity theory applies only to simple lines in relation to each other and from the same velocity to dynamic observers / objects, but here also the question may arise that if the movement of an object is unmanageable, rapid or slow What happens if they start walking around in a spiral or curvilinear way? This question took two years after the publication of the special relativity theory in Einstein's brain. Einstein's curious nature motivated him to expand his theory and develop it in accelerated frames, which can be accelerated relative to one another. Einstein published 'German Year Book of Physics' on November 25, 1915, 100 years ago from today, keeping 'the theory of general relativity', while retaining the prior beliefs of special relativity theory and accelerating the speed. Get done The general relativity theory also calls 'broad relativity theory'. In this theory, Einstein contained the new theory of gravitation. This theory abolished Newton & # 39; s timeless and precise universe concepts. According to some scientists, this principle is 'the greatest intellectual achievement of the best time of all time'. The fact is that the effect of this principle is very broad on the cosmological level.

Actually we are living on earth, due to which we consider 'the geometry of Euclid' to be true, but it is absolutely unreal in the long run. And because of our experiences on Earth we consider Euclid's geometry as true, and the general relativity theory adopts geometry different than the Euclid geometry. So understanding the general relativity theory has been considered more challenging than expected.

One event is famous about the mysteries of this theory. The name of Sir Arthur Eddington is considered to be one of the earliest persons who believe in the theory of relativity. A physicist had even said about him: "Sir Arthur! You are one of the three greatest people in the world who understand the theory of relativity. "Upon hearing this, Sir Arthur got upset. Then the physicist said, "What is the need to be so hesitant?" Sir Arthur said, "There is no question of hesitation, but I myself was thinking that who could be the third person? ''

One such joke was very popular on the Internet a few years ago, which was about a professor named Smith. "Professor Smith composed a book to make people understand the theory of relativity in simple language." Someone wrote about that book - "Professor Smith is more talented than Einstein. When Einstein first described the theory of relativity, only twelve scientists in the whole world understood their theory. But when Professor Smith explains it, no one understands. "

The general relativity theory is based on Equivalence Principle, and according to it, the gravitational force keeps moving from the velocity of light. To understand the rule of equality, imagine that there is a closed room on earth for experiments related to physics and there is another room (9.8 meters / s.) In space making it the same, both rooms will be identical to experiment. Indeed, Einstein proved by the rule of equality that acceleration and gravitation produce the same effect. For this, they resorted to the conceptual use of famous 'lift experiments'.

First of all imagine you have a lift, which is on the top floor of a building. The lift wire is cut and the lift starts falling down freely. When lift starts to fall, weightlessness will have an impact on people who ride in it, in the same manner as the astronauts who ride in the spacecraft. At that time, there will be an uninterrupted experience of falling at the speed of the earth. If a person who is present inside the lift and does not see any scene outside the lift, then his experience will be exactly the same way as the space travelers. No one can tell whether the events in the elevator decreased due to gravity or due to acceleration. So according to the principle of general relativity, acceleration and gravity basically produce the same effect and it is impossible to clarify the difference between them.

In reality, according to Einstein's theory, gravity is not a force, but is a factor of acceleration and slowing down and makes planetary trails near the Sun and sub-pathway near planets curvilinear. There is a time-bound curve surrounding a highly endangered body. In fact, it is now known that the planets around them are orbiting the elliptical orbits due to the Sun's gravitational force, but it would be far more appropriate to say that the mass of the Sun curves the space-time around it Lets do it. And due to the curvature of the epoch, the Moon revolves around the Earth.

The events that occur in this physical world are created by three dimensions of length, width and height of space (space). However, according to the general relativity theory, in addition to the three dimensions of Dick, the fourth dimension 'time' also joins. And these four dimensions are joined by creating the 'Spacetime Continuum'.

With the help of this innovative theory, Einstein had a clear explanation of the problem, for which the physicists were too skeptical of the time. The problem was - deviation in the orbit of planet Mercury near the Sun. According to Newton's rules this deviation could not be fully understood. The difference was only a little. Einstein also solved this problem by general relativity theory, according to him, deviation of 43 seconds should be extra in every century; And it matched deviation inspections. And in this way, Einstein presented himself the first proof of general relativity theory.

The general relativity theory predicted another, that there should be immense displacement (red-shift) in the light coming from the very strong gravitational field, which was not in line with Newton's principles. Excessive displacement was detected in the light coming from the strong gravitational field by detailed astronomical observations, which matched exactly with the calculation of Einstein's theory.

On March 29, 1919, a group of British astronomers led by Sir Arthur Stanley Eddington, on the occasion of the solar eclipse, made images of solar eclipse in West Africa (Princip) and Brazilian city Sobral. According to general relativity, when the light of the stars passes through the strong gravitational field of the sun, it should be turned slightly that means that stars should be displaced from their place. According to Einstein, there should be about 1.75 angle seconds displacement, while Eddington's team discovered displacement of about 1.64 angular seconds. In the year 1952, an American campaign detected the displacement of 1.70 angle seconds with extremely subtle device. And in the later campaigns, some similar results were achieved. The interesting thing is that all of these results prove exactly the predicted prediction of Einstein. This effect is known today as 'Gravitational lensing'.

When Einstein found out that his conclusion was confirmed in an experimental way, he wrote to his beloved friend Max Planck in a letter: "By keeping me alive till this day the fate has given me special favor ... ''. This theory of Einstein is considered to be the world's greatest invention after Newton's gravitational theory. After this, Einstein became the world's most famous scientist and the child and the child became acquainted with him. Even today, when a child shows a greater interest in physics or mathematics, then we are lovingly addressing him as 'Hello Young Einstein'.

Another prediction of general relativity theory was that if acceleration in the movement of a super-natural body, then it would create space and hinges in space which would move away from that body. These lamps produce curvature during periods of time. These waves are now called 'Gravitational Waves'. The speed of these waves is as much as the speed of light, these are similar to those of light waves. Each accelerating celestial body of the universe produces gravitational waves. The cosmic mass of which the mass is high, the more forceful gravitational waves it produces. Our Earth is accelerated by the Sun's gravity and completes one revolution of the Sun in a period of one year. For this reason, the motion of the earth in the orbit around the Sun produces gravitational waves. But this speed of the Earth is very slow and the mass of our Earth is so low that it is almost impossible to observe the weak gravitational waves produced.

First of all, in the year 1974, two astrophysicists, J. H. Taylor and R. a. Hulls achieved success in catching gravitational waves indirectly. Indeed, these two scientists had discovered two neutrons (pulsars) orbiting each other. Both of which are highly mass and concentrated stars, and each other's orbiting are in high velocity. Due to extremely orbital orbiting, they are also releasing gravitational waves in small quantities. The loss of energy due to the emission of gravitational waves is bound to move these stars towards each other. With this the distance between these stars is gradually decreasing. When it was calculated, this reduction consisted entirely of Einstein's general relativity theory. This was an indirect proof of the presence of gravitational waves. For this confirmation of general relativity theory, Taylor and Hulls were awarded the Nobel Prize in Physics in the year 1993.

Scientists have recently made the first direct observation of gravitational waves. It is believed to be the 'biggest discovery' of the scientific century. This scheme of exploration of gravitational waves is named as the 'Laser Interferometric Gravitational-Wave Observatory' or 'LIGO'. With the help of Lego, the scientists have discovered the gravitational waves emitted from the recent collision between the two Krishna disturbs located away.
