(Everett and Roman 2012) Everett gives an example of an informational paradox: a time traveler copies a mathematical demonstration from a manual, then travels back in time to meet the mathematician who firstly published the demonstration, the mathematician simply copied the demonstration at one time before the publication, in which case the information in the demonstration had no origin. (Toomey 2007) A time traveler who steals a time machine from the local museum to make a journey in time and then give the machine same time to the same museum at the end of the travel (that is, in the past) in this case, the car itself is never built by anyone – it simply exists. The causal loops in backwards time travel involve events that appear to “come from nowhere,” (Smith 2016) paradoxical “self-existent” objects or information, resulting in a bootstrap paradox. ![]() Berkovitz (Berkovitz 2001) and Dowe (Dowe 2001) argue that Mellor fails to establish the impossibility of causality loops. Mellor (Mellor 1998) believes that in such loops the chances of events will not be related to their frequencies, according to the law of the large number. Another answer, Hanley, (Hanley 2004) is to deny that (all) causality loops are inexplicable. Similarly, Meyer (Meyer 2012) argues that if someone asks for an explanation of a loop (as a whole), the fault would fall on the person who asked the question, not on our inability to answer. ![]() Lewis (Lewis 1976) accepts that a loop (as a whole) would be inexplicable, such as Big Bang or the disintegration of a tritium atom, but it is just strange, not impossible. There were two main types of response to this objection. Many believe that causality loops are not impossible or unacceptable, but only inexplicable. Four-dimensional geometry provides the means to record the travel of the time traveler. This Parmenidean world of temporal stages immediately removes the “no destination” objection to the time travel. (Lewis 1976) However, the time traveler is not like other aggregates “If he travels to the past it is a zigzag line.” (Lewis 1976) There may also be broad lines that are travels in the future. The world in which we live has, according to David Lewis, a Parmenidean ontology: “a manifold of events in four dimensions,” and the occupants of the world are the 4-dimensional aggregates of the stages – “temporal lines”. (Hawking 1992) Monton (Monton 2009) criticizes Hanley’s example but agrees with his statement. (Faye 2001)īackwards time travels determine causality loops? Hanley (Hanley 2004) asserts that there can be a backward time travel and a reverse causality without any causal loops. If there are no such causes or events, it is said that the loop is causally isolated.īackward causality presupposes a closed ontological future – a metaphysical time position usually called eternalism, a specific form of non-presentism. In a causal loop there may be secondary causes or external events. ![]() (Lobo and Crawford 2002) Events that form a loop must not be the complete causes of each, nor the complete effects of another. (Rea 2014) At such events in spacetime their origin can not be determined. (Horwich 1987) If an event A causes a previous event B, bilking recommends an attempt to de-correlate A and B, that is to bring A in cases where B did not occur and prevent A in cases where B occurred.Ī causal loop is a sequence of events (actions, information, objects, people) (Lobo and Crawford 2002) where an event A causes another event B, which determines the first event A. The classic argument against backward causality is the bilking argument. (Bolonkin 2011) These types of temporal paradoxes can be avoided by the Novikov self-consistency principle or by a variation in the interpretation of many worlds with interacting worlds. There is, among some scientists and philosophers, the idea that any theory that would allow the time travel would introduce causal issues. ![]()
