What is the theory of relativity? Curious about the theory of relativity

The theory of relativity is one of the theories that many people are curious about and that comes to the fore from time to time. The theory of relativity, published by Albert Einstein in 1905, is also known as the Special Theory of Relativity. So what is the Theory of Relativity? Here are the questions about the theory of relativity...
The theory of relativity, also known as the Special Theory of Relativity, was explained in 1905 in the Annalen der Physik journal by Albert Einstein in his 2nd article titled "On the electrodynamics of moving bodies" and then in his 5th article "Can the inertness of an object be related to its energy content?" It is a theory of physics explained in the article titled.

What is the theory of relativity?

The theory of relativity, also known as the Special Theory of Relativity, explains the relationship between space and time. Accordingly, time, space and motion are not independent of each other, and they are a relative whole that is interconnected. Object is related to time, time to object, space to movement, movement to space, that is, they are all related to each other.

There were different studies on the theory of relativity before Einstein. Galileo was the first to observe this effect. This theory of Einstein, combined with Galileo's Principle of Relativity, proposes that all observers will always measure the speed of light at the same magnitude, regardless of the state of linear and invariant motion.

Special Relativity Theory emphasizes that distance and time can change depending on the observer. This theory also reveals that matter and energy are linked by the famous formula E=mc². According to the formula E=mc², the sum of the speed of light and mass is equal to energy. The Special Theory of Relativity, which states that the speed of light is the same for all observers regardless of their relative motion, also states that no matter can be accelerated to reach the speed of light.
