Theories
Miles and Wood suggest that the key word is "Limitation"; that is, the effect limits the amount of interference in the past as opposed to completely prohibiting it. This interpretation is supported by the Barry Letts-written Doctor Who radio play The Paradise of Death (1993), where the Third Doctor explains to Brigadier Lethbridge-Stewart that it is possible to leave a location in the TARDIS and arrive at a time before they actually left, since the Effect only stops someone from interfering with their own past. Although the First Doctor claimed that it was impossible to alter history in The Aztecs (1964), and the concept of unchangeable "fixed points in time" has become a recurring concept in the 2005–present revival, other stories such as The Time Meddler (1965), Day of the Daleks (1972), Genesis of the Daleks (1975), Pyramids of Mars (1975), Remembrance of the Daleks (1988), and A Christmas Carol (2010) imply that changing history is still possible.

Famous quotes containing the word theories:
“Philosophers of science constantly discuss theories and representation of reality, but say almost nothing about experiment, technology, or the use of knowledge to alter the world. This is odd, because ‘experimental method’ used to be just another name for scientific method.... I hope [to] initiate a Back-to-Bacon movement, in which we attend more seriously to experimental science. Experimentation has a life of its own.”
—Ian Hacking (b. 1936)
“The wise man regulates his conduct by the theories both of religion and science. But he regards these theories not as statements of ultimate fact but as art-forms.”
—J.B.S. (John Burdon Sanderson)
“We do not talk—we bludgeon one another with facts and theories gleaned from cursory readings of newspapers, magazines and digests.”
—Henry Miller (1891–1980)
