Unlike most advances in physics, the The Theory of Relativity is a geometrical theory of relativity was proposed based on mathematical theory rather than observation. The theory rests on two postulates that are difficult to testgravitation, and then derives mathematically what the physical consequences should be. Those two postulates are stating that the [[speed of light never changes, ]] and that all laws of physics are the same in every (inertial) frame constant for all observers, regardless of reference no matter where it is or how fast it is traveling. This theory rejects [[Isaac Newton]]'s God-given theory of gravitation and replaces it with a concept that there is a continuum of space and time, and that large masses (like the sun) bend space in a manner similar their velocities relative to how a finger can depress an area of a balloon. From this proposed bending of space the expression arose that "space is curved." But experiments later proved that space is flat overalleachother.
Nothing useful has even been built The theory of relativity was proposed based on the mathematical theory (derived from a series of relativitythought experiments by Einstein) rather than observation. Scientists claim The theory rests on two postulates that this is because relativity only applies are themselves difficult to extremely heavy or fast objects test, and rely on future scientists to finally come up with then derives mathematically what the proof that will vindicate their life's workphysical consequences should be (and hence experimentally testable predictions). Most conservatives Those two postulates are skeptical since science that the speed of light never changes, and that all laws of physics are the same in every (inertial) frame of reference no matter where it is supposed to be about finding proof before a theory becomes a fact, not afteror how fast it is traveling. This theory rejects [[Albert EinsteinIsaac Newton]]'s work had nothing to do theory of gravitation and replaces it with the development a concept that there is a continuum of the [[atomic bomb]]space and time, contrary to popular opinion. Only one Nobel Prize has ever been given and that large masses (like the sun) bend space in 1993) that relates a manner similar to relativity, and the validity how a finger can depress an area of that particular award is questionablea balloon. Many things predicted by the theory of relativity, such as gravitons, have never been found despite much searching for them. Many observed phenomenon, such as the From this proposed bending of light passing near space the sun or the advance of the perihelion in the orbit of Mercury, can be also predicted by Newton's theoryexpression arose that "space is curved." But experiments later proved that space is flat overall.
British Historian Paul Johnson declares the turning point in 20th century to have been when fellow Brit Sir Relativity is important for massive or fast-moving bodies: at low mass or high speed, it can be accurately approximated by classical mechanics (such as [[Arthur EddingtonIsaac Newton]], 's laws of motion). At the top English astronomertwo extremes, ventured out on a boat off Africa in 1919 to observe modelling the bending behaviour of starlight around electrons requires that relativistic effects be taken into account (the sun during a total eclipse. The theory chemically significant phenomenon of electron spin arises from relativity predicts twice the bending of ), and light around passing through a region containing many massive objects compared to Newton's theorybodies such as galaxies will be distorted. These are both experimentally confirmed (electron spin was known before relativity arose, and an eclipse is required to darken the sun so telescopic observations confirm that galactic clusters distort the starlight may be seen in proximity to paths of the sunlight passing through them). Eddington liked publicity One of the mathematical consequences of the theory - the well known equivalance between energy and probably dreamed matter, E=mc^2 - predicted the release of winning a Nobel Prizeenergy in nuclear reactions, explaining the source of the sun's fusion energy and upon his return to England declared that his observations proven spurring the theory development of relativityfissile weapons (the [[atomic bomb]]). That Another was good enough for reporters and historians, but the Nobel committee was not impressed and declined to give him an award. Recent analysis effect of Eddington's work revealed that he high-relative-speed ("relativistic") travel on the passage of time: from this relativity was biased in selecting his dataable to explain, and that overall his data was inconclusive about accurately predict, the theory anomalous orbit of relativitythe planet Mercury (travelling at high speed very close to the sun).
Eddington next promoted British Historian Paul Johnson declares the theory of relativity turning point in 20th century to the have been when fellow Briton Sir [[Arthur Eddington]], an esteemed English-speaking world astronomer, ventured out on a boat off Africa in his Mathematical Theory 1919 with a local Army unit to observe the bending of Relativity (1923)starlight around the sun during a total eclipse. As Upon his return to England declared that his observations proven the title suggests, this theory was more a mathematical vision of how the universe should be, rather than what it actually wasrelativity. When a reporter asked In fact recent analysis of Eddington whether only three people even understood 's work revealed that he was biased in selecting his data, and that overall his data was inconclusive about the theoryof relativity. The experiment was later confirmed by more rigorous experiments, Eddington supposedly retorted, "Who's such as those performed by the third?"[[Hubble Space Telescope]].
Just as “social Darwinism” arose from DarwinismLike most significant scientific discoveries, many seized upon the theory of relativity to apply it in has been widely adopted as a vague way to morality and social issuesanalogy with little factual basis. “All things are relative” became popular as atheists and others used relativity to attack Christian values. There remains enormous political support for For example the theory idea of moral relativity that has nothing to do with physics, exists independent of (and Congress continues to spend billions of dollars unsuccessfully searching for particles predicted by substantially predates) the theory of relativity.
