He was bold, wildly intelligent and very strange, saw a ray of light and imagined he was driving it. He looked into the sky and envisioned that space-time was convex. Albert Einstein re-elected the inner functions of nature, the very essence of light, time, energy, and gravity. His ideas fundamentally changed the way we see the universe – and made him the most famous scientist of the 20th century.
We know Einstein as a visionary physicist, but he was also a passionate humanist and anti-war activist. Born in Germany of Jewish descent, Einstein was truly seen as a citizen of the world. The status of the celebrities of his time allowed him to talk about global issues, from pacifism, racism to anti-Semitism in the nuclear disarmament. “My life is a simple thing that noone would care abot,” he once claimed. But in fact, his letters, notebooks and manuscripts tell a dramatically different story.
Einstein saw the universe as a puzzle and took joy in trying to solve its mysteries. All he needed to study the world was his most valuable scientific tool – his intellect.
In 1905, almost a decade after the first “experiment of thought,” Einstein answered questions about the
Special Theory of Relativity. The theory, which is a revolution in the understanding of time and space, is based on Einstein’s remarkable recognition that light always travels at constant speed, no matter how fast you move when you measure it. Einstein’s explorations of the fundamental properties of light also laid the foundations for his most impressive achievement, the General Theory of Relativity. The development of general relativity began with the principle of equivalence, according to which the states of accelerated motion and rest in a gravitational, magnetic field are identical. According to the general theory of relativity: The sense of time is perceived differently at lower magnetic forces. This phenomenon is called the gravitational dilation of time. The trajectories are unexpectedly altered from Newton’s theory of gravity. Even the light rays (where the photons have no mass) change course in the presence of a gravitational, magnetic field. With these principles it interprets the expansion of the Universe, where its distant parts are moving away from us almost at the speed of light, but this is not opposed to special relativity, as it is the very universe that expands.
The Special theory of relativity complements Newton’s motion laws applying them at speeds comparable to the speed of light. It examines phenomena outside the context of our direct perception of the world around us. Our image of the world was shaped by the physiology of our senses through millions of years of evolution. When attempting to put hypothetical questions using the image we have for our daily lives in phenomena that do not affect it, paradoxes, such as the twin paradox, may appear. Such paradoxes have been experimentally confirmed by a series of experimental phenomena such as time expansion, contraction of length, mass-energy equivalence, and are being confirmed daily in modern particle accelerators.
Einstein eventually managed to express the functioning of the universe with the two theories, which result in a unified form of understanding. The position of observation is the constant that gives us a similar view. Einstein, with his brilliant intellect, as a man of the world, managed to develop his view on a large scale outside space and time. Everything is relative and irrelevant in relation to where the observer is. The world moves within the immobility of the universe.
