In 1905 a young, 26-year-old German physicist (then a Bern patent clerk) named Albert Einstein (1879–1955), showed how measurements of time and space are affected by motion between an observer and what is being observed.
To say that Einstein's radical theory of relativity revolutionized science is no exaggeration.
Although Einstein made many other important contributions to science, the theory of relativity alone represents one of the greatest intellectual achievements of all time.
Although the concept of relativity was not introduced by Einstein, his major contribution was the recognition that the speed of light in a vacuum is constant and an absolute physical boundary for motion.
This does not have a major impact on a person's day-to-day life since we travel at speeds much slower than light speed.
For objects travelling near light speed, however, the theory of relativity states that objects will move slower and shorten in length from the point of view of an observer on Earth.
Einstein also derived the famous equation, "E" = "mc"2, which reveals the equivalence of mass and energy. 
In some of his later papers (especially in 1920 and 1924), Einstein gave a new definition of the aether by identifying it with "properties of space".
Einstein also said that in general relativity the "aether" is not absolute anymore, as the gravitational field and therefore the structure of spacetime depends on the presence of matter.
(It also must be said that Einstein's terminology ("i.e."
aether = properties of space) was not accepted by the scientific community.)

The following station of Einstein's scientific discoveries provides a context for the publications listed below, and clarifies the major themes running through his work.
The first four entries come from his Annus Mirabilis papers or miracle year papers.
In 1905, Einstein proposed the existence of the photon, an elementary particle associated with electromagnetic radiation (light), which was the foundation of quantum theory.
In 1909, Einstein showed that the photon carries momentum as well as energy and that electromagnetic radiation must have both particle-like and wave-like properties if Planck's law holds; this was a forerunner of the principle of wave–particle duality.
He would go on to receive the 1921 Nobel Prize in Physics for this work.
Likewise in 1905, Einstein developed a theory of Brownian motion in terms of fluctuations in the number of molecular collisions with an object, providing further evidence that matter was composed of atoms.
A few weeks earlier, he had derived the Einstein relation for diffusion, which was the first example of the general fluctuation-dissipation theorem and allowed a good estimate of the Avogadro constant.
Additionally In 1905, Einstein developed the theory of special relativity, which reconciled the relativity of motion with the observed constancy of the speed of light (a paradox of 19th-century physics).
Special relativity is now a core principle of physics.
Its counterintuitive predictions that moving clocks run more slowly, that moving objects are shortened in their direction of motion, and that the order of events is not absolute have been confirmed experimentally.
Also in 1905, Einstein developed his concept of Mass–energy equivalence.
Its relation "E=mc2" suggested that matter was a form of energy, which was later verified by the mass defect in atomic nuclei.
The energy released in nuclear reactions—which is essential for nuclear power and nuclear weapons—can be estimated from such mass defects.
In 1907 and again in 1911, Einstein developed the first quantum theory of specific heats by generalizing Planck's law.
His theory resolved a paradox of 19th-century physics that specific heats were often smaller than could be explained by any classical theory.
His work was also the first to show that Planck's quantum mechanical law "E=hν" was a fundamental law of physics, and not merely special to blackbody radiation.
Between 1907 and 1915, Einstein developed the theory of general relativity, a classical field theory of gravitation that provides the cornerstone for modern astrophysics and cosmology.
General relativity is based on the surprising idea that time and space dynamically interact with matter and energy, and has been checked experimentally in many ways, confirming its predictions of matter affecting the flow of time, frame dragging, black holes,</ref> and gravitational waves.
In 1917, Einstein published the idea for the Einstein–Brillouin–Keller method for finding the quantum mechanical version of a classical system.
The famous Bohr model of the hydrogen atom is a simple example, but the EBK method also gives accurate predictions for more complicated systems, such as the dinuclear cations H2+ and HeH2+.</ref>  In 1918, Einstein developed a general theory of the process by which atoms emit and absorb electromagnetic radiation (his "A" and "B" coefficients), which is the basis of lasers (stimulated emission) and shaped the development of modern quantum electrodynamics, the best-validated physical theory at present.
In 1924, together with Satyendra Nath Bose, Einstein developed the theory of Bose–Einstein statistics and Bose–Einstein condensates, which form the basis for superfluidity, superconductivity, and other phenomena.
In 1935, together with Boris Podolsky and Nathan Rosen, Einstein put forward what is now known as the EPR paradox, and argued that the quantum-mechanical wave function must be an incomplete description of the physical world.
In the final thirty years of his life, Einstein explored whether various classical unified field theories could account for both electromagnetism and gravitation and, possibly, quantum mechanics.
However, his efforts were unsuccessful, since those theories did not match experimental observations.  
End of aether?Special Relativity.
Aether theory was dealt another blow when the Galilean transformation and Newtonian dynamics were both modified by Albert Einstein's special theory of relativity, giving the mathematics of Lorentzian electrodynamics a new, "non-aether" context.
Unlike most major shifts in scientific thought, special relativity was adopted by the scientific community remarkably quickly, consistent with Einstein's later comment that the laws of physics described by the Special Theory were "ripe for discovery" in 1905.
Max Planck's early advocacy of the special theory, along with the elegant formulation given to it by Minkowski, contributed much to the rapid acceptance of special relativity among working scientists.
Einstein based his theory on Lorentz's earlier work.
Instead of suggesting that the mechanical properties of objects changed with their constant-velocity motion through an undetectable aether, Einstein proposed to deduce the characteristics that any successful theory must possess in order to be consistent with the most basic and firmly established principles, independent of the existence of a hypothetical aether.
He found that the Lorentz transformation must transcend its connection with Maxwell's equations, and must represent the fundamental relations between the space and time coordinates of inertial frames of reference.
In this way he demonstrated that the laws of physics remained invariant as they had with the Galilean transformation, but that light was now invariant as well.
With the development of the special relativity, the need to account for a single universal frame of reference had disappeared — and acceptance of the 19th century theory of a luminiferous aether disappeared with it.
For Einstein, the Lorentz transformation implied a conceptual change: that the concept of position in space or time was not absolute, but could differ depending on the observer's location and velocity.
Moreover, in another paper published the same month in 1905, Einstein made several observations on a then-thorny problem, the photoelectric effect.
In this work he demonstrated that light can be considered as particles that have a "wave-like nature".
Particles obviously do not need a medium to travel, and thus, neither did light.
This was the first step that would lead to the full development of quantum mechanics, in which the wave-like nature "and" the particle-like nature of light are both considered to be descriptions of the same thing.
A summary of Einstein's thinking about the aether hypothesis, relativity and light quanta may be found in his 1909 (originally German) lecture "The Development of Our Views on the Composition and Essence of Radiation".
Lorentz on his side continued to use the aether concept.
In his lectures of around 1911 he pointed out that what "the theory of relativity has to say ... can be carried out independently of what one thinks of the aether and the time".
He commented that "whether there is an aether or not, electromagnetic fields certainly exist, and so also does the energy of the electrical oscillations" so that, "if we do not like the name of "aether", we must use another word as a peg to hang all these things upon."
He concluded that "one cannot deny the bearer of these concepts a certain substantiality".
