A spacetime diagram is typically drawn with only a single space and a single time coordinate. Fig. 2-1 presents a spacetime diagram illustrating the world lines (i.e. paths in spacetime) of two photons, A and B, originating from the same event and going in opposite directions. In addition, C illustrates the world line of a slower-than-light ...
"Age of X" is a comic book storyline published by Marvel Comics as part of its X-Men series. The storyline is set in an alternate reality known as Earth-11326 . Running from January to April 2011, it is similar in name and tone to the 1995 " Age of Apocalypse " storyline.
A spacetime diagram is a graphical illustration of locations in space at various times, especially in the special theory of relativity.Spacetime diagrams can show the geometry underlying phenomena like time dilation and length contraction without mathematical equations.
x causally precedes y if y − x is future-directed null or future-directed timelike. It gives a partial ordering of spacetime and so can be written x ≤ y. Suppose x ∈ M is timelike. Then the simultaneous hyperplane for x is {y : η(x, y) = 0}. Since this hyperplane varies as x varies, there is a relativity of simultaneity in Minkowski space.
Earth X is a 1999 comic book limited series published by American company Marvel Comics. Earth X was written by Jim Krueger with art by John Paul Leon. Based on Alex Ross' notes, the series features a dystopian version of the Marvel Universe. The series was followed by two sequels, Universe X and Paradise X, and a prequel, Marvels X.
The principle of local Lorentz covariance, which states that the laws of special relativity hold locally about each point of spacetime, lends further support to the choice of a manifold structure for representing spacetime, as locally around a point on a general manifold, the region 'looks like', or approximates very closely Minkowski space ...
Theorists generally identify two historical periods in which time–space compression occurred; the period from the mid-19th century to the beginnings of the First World War, and the end of the 20th century. In both of these time periods, according to Jon May and Nigel Thrift, "there occurred a radical restructuring in the nature and experience ...
"X-Tinction Agenda" not only reunited the X-Men after a prolonged period in which the team had been scattered around the globe (following the events of Uncanny X-Men #246-251), but featured the combined might of the three mutant teams for the first time, in their fight against the mutant-exploiting Genoshan government.
