• Everything You Always Wanted to Know About Time Travel

  http://www.lifesci.sussex.ac.uk/home/John_Gribbin/Time_Travel.html
  A collection of brief articles by the renowned non-fiction author John Gribbin. Includes "How to build a time machine", articles about wormholes and time travel, and a discourse on the question whether the laws of physics forbid travel into the past.

• Getting in a Twist over Time

  http://www.spacedaily.com/news/timetravel-01a.html
  Article on Space Daily about Ron Mallet's attempts to design a time machine using a loop of laser light. By Michael Brooks; also includes a brief history of time travel in relativity, including remarks on wormholes and the chronology protection conjecture.

• How to Build a Time Machine

  https://www.scientificamerican.com/article/how-to-build-a-time-machi-2002-09/
  Article in Scientific American, written by Paul Davies. Covers time travel into the future in special and general relativity and a variety of hypothetical mechanisms for time travel into the past, such as cosmic strings and wormholes, including caveats such as the chronology protection conjecture. Images not available in the free version.

• NOVA Online: Time Travel

  http://www.pbs.org/wgbh/nova/time/
  Companion site to the NOVA program "Time Travel" (1999); includes a description of the connection with Einstein's theories of relativity, an interview with Carl Sagan, a teacher's guide, and a transcript of the show.

• Quantum Time Travel

  http://www.npl.washington.edu/AV/altvw45.html
  Brief description of the work by Yakir Aharonov's group on a "quantum time machine", including parallels with published science-fiction stories. From John G. Cramer's column "The Alternate View", published in Analog Science Fiction and Fact Magazine.

• Space-Time Physics and the Future of Time Travel

  http://themaclellans.com/timetravel.html
  Elementary exposition of Euclidean geometry, Newton vs. Einstein, and the possibility to travel into the future, and see into the past, in relativity. By Alex MacLellan.

• Taking the Cosmic Shortcut

  http://www.abc.net.au/science/slab/wormholes/default.htm
  Article on the site of the Australian Broadcasting Corporation about the physics of time travel, from special relativity and time travel into the future to general relativity, Ron Mallet's time machine, and wormholes. By Elizabeth Warnes.

• The Relativistic Asynchronous Machine

  http://www.relativistische-asynchronmaschine.de/dok_en.html

• Time Loops

  http://www.edge.org/3rd_culture/davies/davies_index.html
  An interview on Edge with the author and physicist Paul Davies about time travel and the ensuing paradoxes, physical time-travel scenarios from Gödel's universe to wormholes, and the interplay between physics and science-fiction. Includes both a transcript and a video version.

• Time Travel - Fact or Fiction?

  http://math.ucr.edu/home/baez/physics/Relativity/GR/time_travel.html
  Brief overview of physics issues related to time travel, including the question of conversation laws, general relativity, possible paradoxes, and the notion of tachyons. From the Physics FAQ; original by Jon J. Thaler.

• Time Travel and Modern Physics

  http://stanford.library.usyd.edu.au/archives/fall2001/entries/time-travel-phys/
  Article from the Stanford Encyclopedia of Philosophy about the basis of time travel scenarios in modern physics, including a discussion of mechanisms such as wormholes, and the question of paradoxes.
