A "{{w|tachyon}}" is a theoretical or thought-experiment particle which travels {{w|Faster-than-light|faster}} than the {{w|speed of light}}. It has many strange properties, including being able to go back in time. This is how the newscaster is able to send a beam back in time to kill her past self. The comic does not explain {{w|Grandfather paradox|the paradox}} of how someone who died in the past could still be alive in the present/future, nor any of the many other paradoxes that arise when {{w|time travel}} is involved, a [[:Category:Time travel|recurring theme]] in xkcd. | A "{{w|tachyon}}" is a theoretical or thought-experiment particle which travels {{w|Faster-than-light|faster}} than the {{w|speed of light}}.

It is a theoretical device which would allow messages to be sent to the past. The text then continues to answer the question via a message from the future (presumably sent by antitelephone). The answer is ''No'' - there will never be a greater physics term. |
