Theory of Everything

A '''theory of everything''' (ToE) explains and links together all known physical phenomena,
all the particles and forces of nature. The primary problem in producing a ToE is that the 
accepted theories of quantum mechanics and general relativity are hard to combine:

: "These days it seems like every physicist is an Indiana Jones on the hunt for the Holy Grail, a theory that can unite the fractured worlds of quantum mechanics and general relativity - Einstein's theory of gravity - and bring order to the universe. Some call it a 'theory of everything', some call it 'quantum gravity', but for decades nearly everyone has been using the same old treasure map - the one drawn up by string theory." (New Scientist, "Four radical routes to a theory of everything")

The New Scientists lists four radical routes to a theory of everything:
"Causal dynamical triangulations" ([http://www.phys.uu.nl/~loll/Web/title/title.html Renate Loll])
"Quantum Einstein gravity" ([http://wwwthep.physik.uni-mainz.de/~reuter/ Martin Reuter])
"Quantum graphity" ([http://www.perimeterinstitute.ca/index.php?amp;option=com_content&task=view&id=30&Itemid=72?=Fotini_Markopoulou Fotini Markopoulou]), 
"Internal relativity" (Olaf Dreyer)

== Principle of Everything ==

If there is a principle of everything (PoE) it is certainly [[Evolution|evolution]]. If all the physical, chemical and biological particles with their corresponding scientific laws emerged bit by bit during the course of evolution, the theory of evolution is the only important and fundamental theory left, because the only thing that has not changed in the last 14.6 billion years since the
universe exists is evolution itself. If you want to know why the world is as complex as it is, the theory of evolution is the right choice. Maybe it can also be applied to the most fundamental level as a kind of [[Quantum Evolution]].
