Question: How complete is the theory of relativity?
About the article "General relativity", section "Current status".

Candidate passages:
The theory of relativity, or simply relativity in physics, usually encompasses two theories by Albert Einstein: special relativity and general relativity.
(The word "relativity" can also be used in the context of an older theory, that of Galilean invariance.
)Concepts introduced by the theories of relativity include: Measurements of various quantities are "relative" to the velocities of observers.
In particular, space and time can dilate.
Spacetime: space and time should be considered together and in relation to each other.
The speed of light is nonetheless invariant, the same for all observers.
The term "theory of relativity" was based on the expression "relative theory" () used by Max Planck in 1906, who emphasized how the theory uses the principle of relativity.
In the discussion section of the same paper Alfred Bucherer used for the first time the expression "theory of relativity" ().

If general relativity is considered one of the two pillars of modern physics, quantum theory, the basis of understanding matter from elementary particles to solid state physics, is the other.
However, it is still an open question as to how the concepts of quantum theory can be reconciled with those of general relativity. 
Conservapedia has also received criticism for its articles regarding the theory of relativity, particularly on their entry titled "Counterexamples to relativity", an article that lists examples purportedly demonstrating that the theory is incorrect.
Attention was drawn to the article by a "Talking Points Memo" posting, in which they reported on Conservapedia's entry and stated that Andy Schlafly, Conservapedia's founder, "has found one more liberal plot: the theory of relativity".
"New Scientist", a science magazine, criticized Conservapedia's views on relativity and responded to several of Conservapedia's arguments against it.
Against Conservapedia's statements, "New Scientist" stated that one is unlikely to find a single physicist that would claim that the theory of general relativity is the whole answer to how the universe works, and said that the theory of relativity has passed every test that the theory has been put through.
University of Maryland physics professor Robert L. Park has also criticized Conservapedia's entry on the theory of relativity, arguing that its criticism of the principle as "heavily promoted by liberals who like its encouragement of relativism and its tendency to mislead people in how they view the world" confuses a physical theory with a moral value.
In a similar statement, "New Scientist" stated at the end of their article that:In October 2010, "Scientific American" criticized Conservapedia's attitude towards the Theory of Relativity, assigning them a zero score on their 0 to 100 fallacy-versus-fact "Science Index", describing Conservapedia as "the online encyclopedia run by conservative lawyer Andrew Schlafly, implies that Einstein's theory of relativity is part of a liberal plot.
"Another claim is that "Albert Einstein's work had nothing to do with the development of the atomic bomb", and that Einstein was only a minor contributor to the theory of relativity. 
 "de Sitter relativity" is the same as the theory of "projective relativity" of Luigi Fantappiè and Giuseppe Arcidiacono first published in 1954 by Fantappiè and the same as another independent discovery in 1976.
In 1968 Henri Bacry and Jean-Marc Lévy-Leblond published a paper on possible kinematics In 1972 Freeman Dyson further explored this.
In 1973 Eliano Pessa described how Fantappié-Arcidiacono projective relativity relates to earlier conceptions of projective relativity and to Kaluza Klein theory.
Han-Ying Guo, Chao-Guang Huang, Zhan Xu, Bin Zhou have used the term "de Sitter special relativity" from 2004 onwards.
R. Aldrovandi, J.P. Beltrán Almeida and J.G.
Pereira have used the terms "de Sitter special relativity" and "de Sitter relativity" starting from their 2007 paper "de Sitter special relativity".
This paper was based on previous work on amongst other things: the consequences of a non-vanishing cosmological constant, on doubly special relativity and on the Newton–Hooke group and early work formulating special relativity with a de Sitter space From 2006 onwards Ignazio Licata and Leonardo Chiatti have published papers on Fantappié-Arcidiacono theory of relativity pointing out that it is the same thing as de Sitter relativity In 2008 S. Cacciatori, V. Gorini and A. Kamenshchik published a paper about the kinematics of de Sitter relativity.
