Quantization of the universe as a black hole

It has been shown that black holes can be quantized by using Bohr's idea of quantizing the motion of an electron inside the atom. We apply these ideas to the universe as a whole. This approach reinforces the suggestion that it may be a way to unify gravity with quantum theory. © 2011 Springer Science+Business Media B.V.Fullana Alfonso, MJ.; Alfonso-Faus, A. (2012).
