How The Einstein Theory Relativity Changed The Way We Think About Gravity?

The secret of gravity which is subject to Einstein's general theory of relativity was revealed in a series of papers submitted to the Prussian Academy in Berlin in November of a century ago.

In 1905, Einstein established that the laws of physics are the same for non-accelerated observers : the light speed in a vacuum is independent of the movement of the observers. A decade later, in his special theory of relativity, matter and energy merged into a unity of space and time called space-time. Nach years of struggle, Einstein succeeded in demonstrating that matter and space-time interact by imitating Newton's naive idea that masses attract each other.

Over the years, many experiments and discoveries have shown that Einstein's theory is the best explanation for gravity and many features of the universe that scientists have. In November 1915 Einstein's gravity was described in the 10 clumsy field equations of the general theory of relativity. The equations state that gravity is the way space-time is made to go warp, bend and stretch. In general, Einstein had a thorough explanation of what gravity causes and how it affects matter, light and time.

New measurements have been made of things like the curvature of light and the slowing of time, and general relativity is the mathematics that gets the right answers.

Scientists who deal, for example, with the general theory of relativity recognize that the universe is constantly growing. Based on Einstein's theory, astronomers can now find out that the universe in which we live began with a big explosion. The mathematics used to explain general relativity has also led experts to predict that fantastic objects such as black holes exist.

A century ago, the physicist Albert Einstein unveiled a theory that changed the world: the general theory of relativity. The general theory of relativity is full of mind-twisting concepts such as distorted space-time and time dilation. The theory cemented Einstein's place at the top of the pantheon of scientific minds and made him a modern icon.

The theory of relativity developed by Albert Einstein in 1905 is the idea that all laws of physics are equal. It states that all laws in the universe are the same for stationary, non-moving objects and observers. The theory explains the behavior of objects in space and time, and it has been used to predict everything from the existence of black holes and the light curvature of gravity to the behavior of the planet Mercury and its orbit.

In his General Theory of Relativity, Einstein established that massive objects with distortions in space and time sense gravity. The theory of relativity helps to explain the movement of planets, the effects of gravity on light and the existence of black holes. In a theory of static gravitational fields, gravity bends the light and slows the clock so that the speed of light changes from place to place.

Einstein's first concrete step on his way to the general theory of relativity came in 1907 when he asked Johannes Stark to write a review article on the theory of relativity for Stark's yearly publication The journal Radioactivitaet electronik. Albert Einstein's General Theory of Relativity was published in March 1916 in the journal Annalen der Physik. It was a revolutionary story because it marked a great leap forward against the laws of universal gravity established by Sir Isaac Newton in 1687.

In 1905 Einstein presented a more moderate version of his theory - the Special Theory of Relativity - that left gravity alone to describe the relationship between space and time. Einstein himself attributed his success to the discovery of a deeper relationship between mathematics and the physical world.

Einstein was inspired by Mach's relational view, because he hoped that his new theory of gravity would secure the relativisation (inertia-bound) of space-time, in which matter does not exist separately from one another. In 1918 Einstein described the principles of Mach as the philosophical pillar of general relativity, the physical principle of equivalence, and the mathematical pillar of general covariance.

Einstein developed his famous equation E = mc2, which states that energy is equal to mass times the speed of light squared in a vacuum. A more moderate version of his theory states that velocity is equal in a vacuum and that the laws of physics do not change with respect to inert objects.

Ten years ago, he shook the world of physics by theorizing that space and time are dynamic, distorted, and influenced by how objects move faster than light. In June, he completed the Special Theory of Relativity, which revealed that space-time behaves in an astonishing way, one that anticipates shorter distances, velocities, and duration relative to and dependent on the observer. Ten years later, General Relativity offered a more comprehensive, explanatory vision, adding gravity to the space-time continuum.

Einstein established with the special theory of relativity that nothing can travel faster than the light speed. The speed limitation of the universe called into question the assumptions inherent in Newtonian laws of gravity - that gravity is an effect of distance forces.

This assumption was not based on first principles, and Newton's theory did not address this question. In his special theory of relativity, motion could exceed the light speed, and that is the speed limit of the universe. The theory of relativity is discussed in more detail in Theory of Relativity, the third volume of the text, but we will say a few words here.

Sir Isaac Newton quantified the gravity between two objects when he formulated his three laws of motion. Albert Einstein stated in his special theory of relativity that the laws of physics for all non-accelerated observers are the same and he showed that in a vacuum the light speed is equal regardless of the speed at which the observer moves.

When a massive object like the Sun bends the infinite fabric of the stretched ceiling of its gravity, this light can no longer move in a straight line through the Sun. Instead, time moves more slowly near a powerful gravitational field like that of a planet than in the void of space. This means that the apparent position of the background stars (which is seen in the sky by the sun even during solar eclipses) appears to shift in the absence of the sun because gravity bends the light.
