Sir Isaac Newton's theory of gravity was written in 1687, however he did not come up with a theory of relativity. The first person to come up with a theory of relativity was Galileo Galilei, but this theory turned out to be incorrect. In a paper in 1905 Albert Einstein built upon Galileo's ideas and produced the special theory of relativity. This is a very famous paper that turned the physics world on its head. The equivalance of mass and energy in his most famous equation, was deduced as a result of this theory. Furthermore, In 1916 Albert Einstein produced the General theory of relativity, a theory of gravitiation which is an extremely successfulvand famous theory. This is the gravitation theory that we use today, as it is supremely accurate. However, Newtons theory of gravitiation works well for speeds much less than the speed of light in a vacuum, and has the benefit of being much less complex!
Depends what you mean by "completed." Both special and general relativity are "complete" in that they fully describe that part of the Universe that they INTEND to describe. However, neither describes EVERYTHING. General relativity, for example, is a more complete theory than is special relativity. However, even GR is useful only for gravity, saying nothing about electro-magnetism (EM) in our Universe. Einstein was fully cognizant of this fact, and figured it would take a decade or so AT MOST to add EM to a fuller theory of relativity. Unfortunately, he was wrong -- not only is EM no closer to being combined with GR today than it was in 1915, but we now know that there are other forces we need to integrate into a more general theory! And even WORSE, we now know about quantum mechanics, which is mathematically IMPOSSIBLE to combine with GR. The final "completion" of relativity -- an combination of all forces with GR and QM -- still awaits us. If any person is able to devise a "Theory of Everything," s/he would go down in history in the same vein as Einstein or Newton.
Then we would not be here in theoretical physics today.
rs today uses General Administrative Theory
Fools rush in where angels fear to tread... I am not about to suggest that I know a flaw in any theory, let alone those of Einstein. They don't call him an 'Einstein' for nothin'. But scientists do point out that Einstein's equations apparently break down at what we would call today a singularity. It seems too that for this and other reasons, Quantum Theory may one day supplant Relativity. It was once thought that Relativity and Quantum Theory could not co-exist; there are now some possibilities that they can be reconciled. Whether or not the theories of Relativity are proven wrong, they were central to an amazing burst of insight on the part of many great scientists in the early decades of the 20th century.
Yes ,we do still use the theory of relativity as it deals with the relativity of motion and rest. And, it is of great importance for the micro-world like sub-atomic phenomena of nuclear interactions. So the theory of relativity will be always useful.
The theory of relativity, proposed by Albert Einstein, has had a profound impact on our understanding of the nature of time, space, and energy. It has led to advancements in technology such as GPS systems, nuclear power, and particle accelerators. Additionally, the theory has influenced fields such as cosmology and astrophysics, shaping our understanding of the universe.
Special relativity is a fundamental pillar in our understanding of the Universe. Many things are based on it, like the GPS system and nuclear power. Indirectly much of nano technology is based on special relativity so things like iPads, computers, modern cars, all have ingredients which can be traced back to the theory of special relativity.
Albert Einstein's discoveries, such as the theory of relativity, revolutionized our understanding of the universe by showing the interconnectedness of space, time, and energy. His work laid the foundation for modern physics and had practical implications in various fields, from the development of advanced technology to the exploration of outer space. Einstein's contributions continue to inspire further scientific research and innovation today.
Albert Einstein is known for his groundbreaking work in theoretical physics, particularly his theory of relativity. He received the Nobel Prize in Physics in 1921 for his discovery of the photoelectric effect, which led to the development of quantum theory. Einstein's theories revolutionized our understanding of space, time, and the universe.
Short answer: As for today, we do not know for certain. It is by existing theory, Einstein's theory of relativity, impossible for matter (mass) to reach the speed of light.A little longer: By Theory of relativity, the energy which is required to reach the speed of light is a limit which stretch to infinity. As energy can't be created nor destroyed, there is a finite amount of energy in the universe, and the speed of light cannot be reached.
White holes were derived from the theory of relativity by Albert Einstein though never proven. Einstein's theory was expanded by the Schwarzschild metric. Theorists today are attempting to theorize that there is a big bang everyday in black holes where light and matter is released and might answer on how our universe was formed.
