May 26, 2016 · FAQ: Time dilation in special vs. general relativity What is time dilation in special relativity? Time dilation in special relativity is the phenomenon where time appears to pass slower for an object that is moving at high speeds compared to an object at rest.

Jun 10, 2012 · FAQ: Proper Time in Special vs. General Relativity What is the concept of "proper time" in special and general relativity? The concept of "proper time" refers to the time experienced by an observer who is at rest relative to a specific event or object. It is the time interval measured by a clock that is in the same reference frame as the observer.

Jun 6, 2005 · The modern view [used by working relativists] is that General Relativity works with a spacetime consisting of an arbitrary 4-manifold [tex]M[/tex] with a lorentzian metric tensor field [tex]g_{ab}[/tex], whereas Special Relativity is the special case where the spacetime is the Minkowski spacetime consisting of [tex]R^4[/tex] and the [flat] Minkowski metric …

Jan 4, 2013 · Either I am totally misunderstanding you, or we are saying the same thing. I use general relativity to deal with the general case of non-zero curvature. In the special case of of zero curvature the more general methods of general relativity still work just fine, but in this special case these methods reduce to special relativity.

Jan 11, 2015 · FAQ: General relativity vs special relativity What is the difference between general relativity and special relativity? General relativity describes the effects of gravity on the fabric of space-time, while special relativity describes the relationship between space and time in the absence of gravity.

Oct 12, 2012 · Galilean Galilean relativity Relativity Special relativity In summary, the conversation discusses the concept of Galilean relativity and its relationship to the speed of light. While some argue that Galilean relativity can be thought of as the limiting case where light speed is infinite, others argue that this is not a useful way to think about it.

Apr 30, 2007 · Here, as in general relativity, subtleties in the nature of the interaction "conspire" to disguise the effect of propagation delay. It should be emphasized that in both electromagnetism and general relativity, this effect is not put in ad hoc but comes out of the equations. Also, the cancellation is nearly exact only for constant velocities.

Jul 8, 2007 · Does SR appear as the special case of GR when T_{\\mu\\nu}=0 in which case the solution of Einstein's equation is the Minkowski metric? And what are the Ricci tensors and scalar curvature like in the case T_{\\mu\\nu}=0?

May 12, 2014 · "Special" and "General" relativity are both theories proposed by Albert Einstein to explain the behavior of objects in space and time. "Special" relativity deals with the relationship between space and time for objects moving at a constant speed, while "General" relativity expands on this theory to include the effects of gravity.

Feb 21, 2024 · The theory of relativity, formulated by Albert Einstein, comprises two fundamental theories—special and general relativity. Special relativity, proposed in 1905, redefines our understanding of space and time by asserting the constancy of the speed of light for all observers and introducing concepts like time dilation and length contraction.
