The general theory of relativity, Einstein asserted, was now complete. ... It culminated with Einstein’s radically new vision of the interplay of space, time, matter, energy and gravity, a feat ...
Just as moving clocks run slow, General Relativity predicts that clocks in gravitational fields run slow. This prediction of the theory has been confirmed many times. A small document that does a non-mathematical derivation of this prediction of the theory has been prepared; the html version is here and the pdf version is here.
General relativity is Einstein's theory of gravity, in which gravitational forces are presented as a consequence of the curvature of spacetime. In general relativity, objects moving under gravitational attraction are merely flowing along the "paths of least resistance" in a curved, non-Euclidean space. The amount that spacetime curves depends on the matter and energy present in ...
In general relativity, the metric tensor (in this context often abbreviated to simply the metric) is the fundamental object of study.The metric captures all the geometric and causal structure of spacetime, being used to define notions such as time, distance, volume, curvature, angle, and separation of the future and the past.. In general relativity, the metric tensor plays the role of the ...
The rubber sheet analogy helps with visualization of space-time, but Einstein himself developed a complete quantitative theory that describes space-time through highly abstract mathematics. General relativity is expressed in a set of interlinked differential equations that define how the shape of space-time depends on the amount of matter (or ...
Albert Einstein on space-time. German-born physicist who developed the special and general theories of relativity and won the Nobel Prize for Physics in 1921 for his explanation of the photoelectric effect. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by ...
In summary, Einstein’s theory of relativity redefined our understanding of the universe. Special Relativity showed that space and time are relative and interconnected, leading to phenomena like time dilation and mass-energy equivalence. General Relativity further advanced this by describing gravity as the curvature of spacetime, profoundly ...
