10 hours ago · According to Einstein's theory of general relativity, gravity affects the flow of time. As one ventures deeper into a black hole's gravitational field, time would appear to slow down significantly. This effect, known as time dilation, occurs due to the immense gravitational pull distorting the fabric of space-time.
1 day ago · The special theory of relativity cannot account for gravity. Its successor, the general theory of relativity, explains gravity by recognizing that spacetime is not fixed but instead dynamical. In general relativity, gravitational force is reimagined as curvature of spacetime. A curved path like an orbit is not the result of a force deflecting a ...
10 hours ago · General relativity is widely accepted as the best candidate to describe the gravitational field as a fundamental interaction. An important prediction of general relativity is the prediction of the existence of a particular set of exact solutions, black holes, in which a local curvature singularity is surrounded by an event horizon that does not permit sending information from the interior of ...
10 hours ago · In the context of relativity different suggestions have been made over the years in order to introduce viscosity in a relativistic fluid in such a way that the resulting PDE is hyperbolic in a suitable sense and has the finite speed of propagation property. Recently this subject has come to new life (e.g. [4, 13], consult for more references).

In Euclidean geometry, two parallels lines can never intersect. The shortest distance between two points is a straight line.
