Category. v. t. e. A gravitational singularity, spacetime singularity or simply singularity is a 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".
v. t. e. The Penrose–Hawking singularity theorems (after Roger Penrose and Stephen Hawking) are a set of results in general relativity that attempt to answer the question of when gravitation produces singularities. The Penrose singularity theorem is a theorem in semi-Riemannian geometry and its general relativistic interpretation predicts a ...
The term quantum singularity is used to refer to many different phenomena in fiction. They often only approximate a gravitational singularity in the scientific sense in that they are massive, localized distortions of space and time. The name invokes one of the most fundamental problems remaining in modern physics: the difficulty in uniting ...
Kruskal–Szekeres coordinates on a black hole geometry are defined, from the Schwarzschild coordinates , by replacing t and r by a new timelike coordinate T and a new spacelike coordinate : for the exterior region outside the event horizon and: for the interior region . Here is the gravitational constant multiplied by the Schwarzschild mass ...
August 28, 2024 at 11:06 AM. The effort to build a new Columbus State University Coca-Cola Space Science Center has taken a major step forward. In the University System of Georgia’s $3.6 billion ...
Initial singularity. The initial singularity is a singularity predicted by some models of the Big Bang theory to have existed before the Big Bang. [1] The instant immediately following the initial singularity is part of the Planck epoch, the earliest period of time in the history of our universe.
The technological singularity —or simply the singularity[1] —is a hypothetical future point in time at which technological growth becomes uncontrollable and irreversible, resulting in unforeseeable consequences for human civilization. [2][3] According to the most popular version of the singularity hypothesis, I. J. Good 's intelligence ...
Naked singularity. In general relativity, a naked singularity is a hypothetical gravitational singularity without an event horizon. When there exists at least one causal geodesic that, in the future, extends to an observer either at infinity or to an observer comoving with the collapsing cloud, and in the past terminates at the gravitational ...
