The Noron theory suggests a theoretical means in which to 'travel' to the past using the concept of retarded time. It was proposed in 2008 by Professor Richard Hills<ref>Astrophysics Group members - R Hills</ref> of Cambridge University, in honour of the late Jayesh Noron (a close friend of Hills).
Under the assumption of linear light travel, the time delay between photon emission and observance (retarded time) allows for one situated sufficiently distant from earth to witness events on earth that have transpired in the past, provided extremely large telescopes are used<ref>Charles Seife, Alpha and Omega: The Search for the Beginning and End of the Universe, Penguin 2004.</ref>. However, this assumption prevents a space-travelling observer from witnessing events further back in time from earth departure, as the observer would have to travel faster than the speed of light to catch up to the photons that have been reflected from earth in the past. This discrepancy is called the Noron Paradox.
The Noron theory solves the Noron Paradox with modern theories on the curvature of the universe<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>, stating that this curvature is sufficient to refract earth-originating photons back to earth. This suggests that earth's entire history could be witnessed from earth using high-powered telescopes.
The Noron theory has not yet broken into mainstream astrophysics and is widely unheard of, as Hills was not able to successfully publish his theory.
