The Fermi paradox is the discrepancy between the lack of conclusive evidence of advanced extraterrestrial life and the apparently high likelihood of its existence. As a 2015 article put it, "If life is so easy, someone from somewhere must have come calling by now."
Time travel is the hypothetical activity of traveling into the past or future. Time travel is a widely recognized concept in philosophy and fiction, particularly science fiction. In fiction, time travel is typically achieved through the use of a hypothetical device known as a time machine. The idea of a time machine was popularized by H. G. Wells' 1895 novel The Time Machine.

A lie-to-children is a simplified, and often technically incorrect, explanation of technical or complex subjects employed as a teaching method. Educators who employ lies-to-children do not intend to deceive, but instead seek to 'meet the child/pupil/student where they are', in order to facilitate initial comprehension, which they build upon over time as the learner's intellectual capacity expands. The technique has been incorporated by academics within the fields of biology, evolution, bioinformatics and the social sciences.
The Fabric of the Cosmos: Space, Time, and the Texture of Reality (2004) is the second book on theoretical physics, cosmology, and string theory written by Brian Greene, professor and co-director of Columbia's Institute for Strings, Cosmology, and Astroparticle Physics (ISCAP).
The communication with extraterrestrial intelligence (CETI) is a branch of the search for extraterrestrial intelligence (SETI) that focuses on composing and deciphering interstellar messages that theoretically could be understood by another technological civilization. The best-known CETI experiment of its kind was the 1974 Arecibo message composed by Frank Drake.
Physics World is the membership magazine of the Institute of Physics, one of the largest physical societies in the world. It is an international monthly magazine covering all areas of physics, pure and applied, and is aimed at physicists in research, industry, physics outreach, and education worldwide.
John Richard Gott III is a professor of astrophysical sciences at Princeton University. He is known for his work on time travel and the Doomsday argument.
The Physics of Star Trek is a 1995 non-fiction book by the theoretical physicist Lawrence M. Krauss. It is the third book by Krauss, who later wrote a follow-up titled Beyond Star Trek in 1997.
About Time: Einstein's Unfinished Revolution (ISBN 978-0-684-81822-1), published in 1995, is the second book written by Paul Davies, regarding the subject of time. His first book on time was his The Physics of Time Asymmetry (1977)(ISBN 0-520-02825-2). The intended audience is the general public, rather than science academics.
How William Shatner Changed the World is a 2005 two-hour television documentary, commissioned by Discovery Channel Canada and co-produced for History Channel in the United States and Channel Five in the United Kingdom.
