General Relativity explained like you've never seen before. A super-quick, super-painless guide to the theory that conquered the universe. scroll down. to begin. For 100 years, the general theory of relativity has been a pillar of modern physics. The basic idea is so elegant that you don’t need superpowers to understand it.
special relativity. This is Einstein’s famous strong equivalence principle and it makes general relativity an extension of special relativity to a curved spacetime. The third key idea is that mass (as well as mass and momentum ﬂux) curves spacetime in a manner described by the tensor ﬁeld equations of Einstein.
Jun 04, 2021 · General relativity is physicist Albert Einstein 's understanding of how gravity affects the fabric of space-time. The theory, which Einstein published in 1915, expanded the theory of special ...
functions of a general point (global or ambient coordinates) (y 1, y 2, y 3) on the surface. Question Why are these functions called a chart? Answer The chart above assigns to each point on the sphere (away from the meridian) two coordinates. So, we can think of it as giving a two-dimensional map of the surface of the sphere, just like a ...
Jan 28, 1996 · P. A.M. Dirac. Princeton University Press, Jan 28, 1996 - Science - 69 pages. 6 Reviews. Einstein's general theory of relativity requires a curved space for the description of the physical world. If one wishes to go beyond superficial discussions of the physical relations involved, one needs to set up precise equations for handling curved space.
According to the special theory of relativity, the mass of an object in a frame of reference at rest is called its rest mass m o. if this mass is measured by an observation moving with a constant speed V relative to the object, then it will not remain constant if the speed V is comparable to C.
Superseded theories. Scientific theories are testable and make falsifiable predictions. Thus, it is a mark of good science if a discipline has a growing list of superseded theories, and conversely, a lack of superseded theories can indicate problems in following the use of the scientific method.
