A coordinate singularity occurs when an apparent singularity or discontinuity occurs in one coordinate frame, which can be removed by choosing a different frame. An example of this is the apparent singularity at the 90 degree latitude in spherical coordinates. An object moving due north (for example, along the line 0 degrees longitude) on the ...
Singularity, a 2023 novel by Jeremy Robinson, which is the finale of the "Infinite Timeline" The Singularity , Anne Milano Appel's 2024 English translation of Dino Buzzati's 1960 novel Il grande ritratto ( Larger than Life )
A gravitational singularity, spacetime singularity, or simply singularity, is a theoretical condition in which gravity is predicted to be so intense that spacetime itself would break down catastrophically. As such, a singularity is by definition no longer part of the regular spacetime and cannot be determined by "where" or "when".
The Schwarzschild metric has a singularity for r = 0, which is an intrinsic curvature singularity. It also seems to have a singularity on the event horizon r = r s . Depending on the point of view, the metric is therefore defined only on the exterior region r > r s {\displaystyle r>r_{\text{s}}} , only on the interior region r < r s ...
Voyager flies into the singularity after seeing an image of itself inside, and becomes trapped. To escape, the crew uses a shuttle to fire a tachyon beam at the entry. In the Voyager episode " Hunters ", the crew discover a Hirogen relay station almost 100,000 years old, powered by a quantum singularity, also referred to by Tom Paris as a black ...
Typographical symbols and punctuation marks are marks and symbols used in typography with a variety of purposes such as to help with legibility and accessibility, or to identify special cases. This list gives those most commonly encountered with Latin script. For a far more comprehensive list of symbols and signs, see List of Unicode characters.
