Erireliativsusteoorias, also known as special relativity, is a fundamental theory in physics proposed by Albert Einstein in 1905. It revolutionized our understanding of space, time, mass, and energy. The theory is based on two postulates. The first postulate states that the laws of physics are the same for all non-accelerating observers, meaning that there is no absolute frame of reference. The second postulate asserts that the speed of light in a vacuum is constant for all observers, regardless of their motion relative to the light source.

These seemingly simple postulates have profound implications. They lead to phenomena such as time dilation, where time passes slower for a moving observer compared to a stationary one, and length contraction, where objects appear shorter in the direction of their motion. Another key consequence is the equivalence of mass and energy, famously expressed by the equation E=mc², where E represents energy, m represents mass, and c is the speed of light. This equation implies that mass can be converted into energy and vice versa, a principle that underpins nuclear physics.

Erireliativsusteoorias applies to inertial frames of reference, which are frames that are not accelerating. For accelerating frames and the effects of gravity, Einstein later developed the theory of general relativity. Special relativity has been extensively tested and confirmed by numerous experiments and observations, and it forms the basis for much of modern physics, including particle physics and cosmology.
