Noron theory

The Noron theory suggests a theoretical means in which to 'travel' to the past using the concept of retarded time. It was proposed in passing by Professor Richard Hills<ref>Probing for dynamics of dark energy and curvature of universe with latest cosmological observations Gong-Bo Zhao (Inst. of High Energy Phys., Chinese Acad. of Sci., Beijing, China); Jun-Qing Xia; Hong Li; Tao, C.; Virey, J.-M.; Zong-Hong Zhu; Xinmin Zhang Source: Physics Letters B, v 648, n 1, 26 April 2007, p 8-13</ref>. of Cambridge University, in honour of the late Jayesh Noron (a close friend of Hills). The theory suggests that if one were located far enough away from the earth, one could witness the earth's creation <ref>Charles Seife, Alpha and Omega: The Search for the Beginning and End of the Universe, Penguin 2004.</ref>, as the photons from this event are still traveling through space. This assumes that light travels linearly; however, theories that the universe is curved suggest that this light would bend and eventually return to earth, so that the earth's creation (and entire history) could be witnessed from earth using high-powered telescopes.
