The ‘Heliocentric Model’ is a theory that places which object as the centre of the Universe?
History of the center of the Universe the center of a spherical, stationary Earth, around which the sun, moon, planets, and stars rotate. With the development of the heliocentric model by Nicolaus Copernicus in the 16th century, the sun was believed to be the center of the Universe, with the planets (including Earth) and stars orbiting it. In the early 20th century, the discovery of other galaxies and the development of the Big Bang theory led to the development of cosmological models of a homogeneous, isotropic Universe (which lacks a central point) that is expanding at all points. In religion or mythology, the "axis mundi" (also cosmic
Three-torus model of the universe Three-torus model of the universe 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. The theory describes the shape of the universe (topology) as a three-dimensional torus. It is also informally known as the doughnut theory. 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. In order to understand these CMB results, NASA supported development of two exploratory satellites, the Cosmic Background Explorer (COBE) in 1989 and the Wilkinson Microwave
