Albert Einstein was born in Germany in 1879. He made great achievements in scientific research during his lifetime, the most outstanding of which was that he experimentally confirmed the existence of atoms, founded the theory of relativity, and developed Planck's quantum hypothesis. Albert Einstein, a famous German physicist, made outstanding contributions to the development of modern physics throughout his life.

His most outstanding achievement was that he broke through the framework of Newton's classical physics and created the theory of relativity applicable to the field of microscopic high-speed motion.

Before Einstein, people have believed since ancient times that although matter exists in time and space, and their movement is conditioned by time and space, both time and space are not affected by the distribution of matter and its motion. In this way, time, space, matter, and movement are completely separated and isolated. The genius physicist Isaac Newton also believed in this view, and based on it, he proposed the concepts of absolute time, absolute space, and absolute motion.

Einstein disagreed with Newton's view of absolute space-time and absolute motion, and from the point of view of the finite speed of light, he proposed that the temporal simultaneity of the universe is relative to a certain frame of reference, for example, the time of the events on the moon is relative to the reference frame of the earth. On the basis that simultaneity is relative, he rejects Newton's concepts of absolute time, absolute space, and absolute motion. Because the simultaneity of time is relative to a certain frame of reference, it is all relative; And motion is closely linked to time, so motion is also relative, looking at the earth in isolation, its motion does not exist; Space and time are intimately linked, so there is no such thing as absolute space.

Thus, Einstein connected seemingly unrelated time and space into an intimately interrelated unity of opposites, and in 1905 he created the special theory of relativity.

In 1916, after another 10 years of exploration, Einstein further completed the generalized phase.

On the creation of work. General relativity is a new theory of gravity without gravity, a law of physics that applies to all frames of reference. It is different from special relativity, which only applies to physical processes where gravity is absent.

The study is a frame of reference for the relative motion of a straight line and a uniform velocity; The general theory of relativity is the study of the reference frame for any motion, which is not only suitable for linear and uniform motion, but also for accelerated motion and rotational motion, so it is the second floor of the edifice of relativity. The general theory of relativity further shows that time and space are not isolated, and that the distribution and motion of matter in turn determine the structure of time and space. It also influences each other, and is a unity of opposites.

Einstein's theory of relativity is the most important achievement of modern science and technology in the phantom century, which led to a complete revolution in ancient physics, completed the third major theoretical synthesis of physics, and further laid the cornerstone for the development of modern physics.
