Question

Explain special theory of relativity and general theory of relativity in detail.

Accepted Answer

Albert Einstein's theory of relativity states that space and time are relative, and that all motion must be relative to a frame of reference. It is a belief that states and physical laws are universal. This hypothesis is straightforward but difficult to grasp.
It states that there is no such thing as an absolute reference frame. If the object or momentum is merely in reference to other objects, velocity can be measured. Regardless of who measures it or how fast the person measuring it moves, the speed of light remains constant. The Theory of Relativity, developed by Albert Einstein, is divided into two parts: Special Relativity Theory and General Relativity Theory. This theory was explained by Einstein using two postulates. Regardless of the observer's velocity, the laws of physics are the same for all. Regardless matter whether the light source or the observer moves, the speed of light remains constant. This is the hypothesis that gave rise to the concept of time travel. According to Einstein, as a person's velocity increases, the pace at which time tics drops. However, because the decrease in time is so little in comparison to the rise in time, this is difficult to perceive. As a result, it's reasonable to believe that if you equal the speed of light, you'll be in a position where time stands still. Objects are measured and appear to be shorter in the direction of movement relative to the observer. It's referred to as length shrinkage. This idea also underpins mass energy equivalency.

According to Einstein's General Relativity theory, being at rest in the gravitational field and accelerating are physically equal. An observer can watch the ball fall in the same way on the rocket and on Earth, for example. This is owing to the rocket's acceleration, which is equal to acceleration due to gravity. This theory is related to special relativity and Newton's gravitational theory. The following are some consequences of general relativity:

Time Dilation Due to Gravitational Forces: The passage of time is influenced by gravity. Deeper gravity wells have slower clocks than general gravitational levels.

In the gravitational field, light rays bend. The universe is expanding, and sections of it are travelling faster than the speed of light away from Earth.
