When exploring the theory of relativity, it's essential to consider various aspects and implications. Relativity | Definition, Equations, & Facts | Britannica. Relativity, wide-ranging physical theories formed by the German-born physicist Albert Einstein. Special relativity is limited to objects that are moving with respect to inertial frames of reference. General relativity is concerned with gravity, one of the fundamental forces in the universe. Another key aspect involves, relativity - Time, Space, Mass | Britannica.
This perspective suggests that, to make the speed of light constant, the theory requires that space and time change in a moving body, according to its speed, as seen by an outside observer. The body becomes shorter along its direction of motion; that is, its length contracts. Relativity - Space-Time, Gravity, Physics | Britannica. General relativity | Gravitational Waves, Spacetime & Cosmology ....
It was conceived by Einstein in 1916. It's important to note that, gravity defines macroscopic behaviour, and so general relativity describes large-scale physical phenomena. Special relativity | Definition & Equation | Britannica.

special relativity, part of the wide-ranging physical theory of relativity formed by the German-born physicist Albert Einstein. Along with quantum mechanics, relativity is central to modern physics. How Albert Einstein Developed the Theory of General Relativity.
In his four papers, published in November 1915, Einstein laid the foundation of the theory. In the third in particular he used general relativity to explain the precession of the perihelion of Mercury. The point at which Mercury has its closest approach to the Sun, its perihelion, moves. In relation to this, relativity summary | Britannica. There are two distinct theories of relativity, both proposed by Albert Einstein. The special theory of relativity (1905) developed from Einstein’s acceptance that the speed of light is the same in all reference frames, irrespective of their relative motion.

Astronomy - Relativity, Space-Time, Cosmology | Britannica. A key theoretical development for 20th-century astronomy and cosmology was the development of the theory of relativity, from 1905 to 1915, which eventually led to an explanation of the origin of the universe. E = mc² | Equation, Explanation, & Proof | Britannica. Furthermore, his theory of relativity shifted contemporary understanding of space completely.
Along with his equation E = mc2, it also foreshadowed the creation of the atomic bomb. Albert Einstein's theory of relativity describing absolute quantities .... The special theory of relativity, first described by Albert Einstein, was merely a statement of the realization that we were wrong-- distances in space and time are actually relative.

They change depending on how fast you're moving.
