There is no RationalWiki without you. We are a small non-profit with no staff – we are hundreds of volunteers who document pseudoscience and crankery around the world every day. We will never allow ads because we must remain independent. We cannot rely on big donors with corresponding big agendas. We are not the largest website around, but we believe we play an important role in defending truth and objectivity.
If everyone who saw this today donated $5, we would meet our goal for 2019.

Theory of everything

shoulders of giants.
A theory of everything (or the Unified Field Theory) describes the gravitational, the weak nuclear, the strong nuclear and the electromagnetic forces in a single unifying framework. As things now stand, general relativity offers the best description of gravitational interactions while quantum mechanics addresses the remaining ones in the so-called Standard Model of particle physics. (Note that the Standard Model has already taken into account special relativity.) Hence, formulating a theory of everything is synonymous with unifying general relativity with quantum mechanics. Such a theory would explain everything, at least in principle. For a certain value of "everything", at least; more precisely, it would explain everything about fundamental physics. Such a "theory of everything" differs from the so-called "Grand Unified Theories", which exist but do not include gravity and do not agree with experimental data.
