Editing Theory of everything (section)

===Other attempts===
Among other attempts to develop a theory of everything is the theory of [[causal fermion system]]s,<ref name="CFSIntro">{{Cite journal |author=Finster |first1=F. |last2=Kleiner |first2=J. |date=2015 |title=Causal fermion systems as a candidate for a unified physical theory |journal=Journal of Physics: Conference Series |volume=626 |issue=2015 |page=012020 |arxiv=1502.03587 |bibcode=2015JPhCS.626a2020F |doi=10.1088/1742-6596/626/1/012020 |s2cid=33471826}}</ref> giving the two current physical theories ([[general relativity]] and [[quantum field theory]]) as limiting cases.

Another theory is called [[Causal Sets]]. As some of the approaches mentioned above, its direct goal isn't necessarily to achieve a theory of everything but primarily a working theory of quantum gravity, which might eventually include the standard model and become a candidate for a theory of everything. Its founding principle is that spacetime is fundamentally discrete and that the spacetime events are related by a [[partial order]]. This partial order has the physical meaning of the [[causality relation]]s between relative [[past and future distinguishing]] spacetime events.<!--Please do _not_ insert "Time Cube" and "Heim Theory" here without first gaining a consensus on the talk page for including these theories. Changes without such a consensus will be promptly reverted. Thanks!-->

[[Causal dynamical triangulation]] does not assume any pre-existing arena (dimensional space), but rather attempts to show how the spacetime fabric itself evolves.

Another attempt may be related to [[ER=EPR]], a conjecture in physics stating that [[Quantum entanglement|entangled]] particles are connected by a [[wormhole]] (or Einstein–Rosen bridge).<ref name=Cowen>{{cite journal|last1=Cowen|first1=Ron|title=The quantum source of space-time|journal=Nature|date=16 November 2015|volume=527|issue=7578|pages=290–293|bibcode=2015Natur.527..290C|doi=10.1038/527290a|pmid=26581274|s2cid=4447880}}</ref>
