Three-torus model of the universe

  (Redirected from Doughnut theory of the universe)
A toroidal model of the universe that has superficial similarity to the theory described in this article.

The three-torus model is a cosmological model proposed in 1984 by Alexei Starobinsky and Yakov Borisovich Zel'dovich at the Landau Institute in Moscow.[1] The theory describes the shape of the universe (topology) as a three-dimensional torus. It is also informally known as the doughnut theory.[according to whom?]

Shape of the universeEdit

The cosmic microwave background (CMB) was discovered by Bell Labs in 1964. Greater understanding of the universe's CMB provided greater understanding of the universe's topology[further explanation needed]. In order to understand these CMB results, NASA supported development of two exploratory satellites, the Cosmic Background Explorer (COBE) in 1989[clarification needed] and the Wilkinson Microwave Anisotropy Probe (WMAP) in 2001[clarification needed].
