Jul 10, 2021 · The General Theory of Relativity goes beyond the Special Theory by implying that the gravitational force, and the resultant planetary motion, can be described as pure geodesic phenomena for forceless motion in a four-dimensional Riemannian structure.
Einstein’s Theory of General Relativity is a theory developed by Einstein in order to describe gravity in a way that is consistent with Special Relativity and the propagation of light.

In the olden days. Welcome to another paradigm shift. The principle of equivalence… 1. The absence of a gravitational field (true weightlessness) is indistinguishable from free fall acceleration in a gravitational field (apparent weightlessness). 2. Accelerated motion in the absence of a gravitational field (apparent weight) is indistinguishable fr...
Space-time is more than just a set of values for identifying events. Space-time is a thing unto itself. The cosmological constant is a quantity used in general relativity to describe some properties of space-time. Here's how it goes. Maybe gravity is the curvature of space-time caused by the mass-energy of stuff within it plus the energy of space i...

Whatever makes 2Gm/rc2 approach one, makes the dominator √(1 − 2Gm/rc2)approach zero, and makes the time of an event stretch out to infinity. That happens when an event approaches the following distance from a gravitating body… This distance is known as the Schwarzschild radius. Another way to write the equation for gravitational time dilation is i...

Sep 12, 2022 · Summary. 5.1 Invariance of Physical Laws. Relativity is the study of how observers in different reference frames measure the same event. Modern relativity is divided into two parts. Special relativity deals with observers in uniform (unaccelerated) motion, whereas general relativity includes accelerated relative motion and gravity.
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.
