Topic-Page Credits

Introductory Page

Jennifer Carter drafted the original introductory page drawing from Hayley Dawson’s class project.  We (John and Scott) have significantly expanded it to reflect the addition of topic pages and other changes to the website.

The Grandfather Paradox

Projects by Kayde Little and Matthew Rakow were the basis for this topic page.

The Self-Visitation Paradox

Projects by Nathan Price and Christopher Nattkemper were the basis for this topic page.

The Nowhere Argument

Kelsey Ryan and Catherine Gensel provided the foundation for this topic page. Ian Willard provided significant changes to the layout and content.

The Double-Occupancy Problem

In 2008, I (John Carroll) assigned an exercise about how to understand a passage in Le Poidevin’s paper, a passage that I found difficult. A superb class discussion led to term projects on the double-occupancy problem by Daniel Ellis, Daniel Farrell, David Fenwick, Supun Koralalage, Jennifer Leaf, Brandon Moore, and Jeffrey Vohlers, several with helpful animated graphs, several with excellent text. These projects suggested the plausible solutions presented here. Among those doing the best projects on double occupancy, Daniel Ellis and Brandon Moore had the time and interest to work with me off and on over the past several years to produce the present topic page. Our thanks to the entire class. Versions of this topic page were presented as papers to the NC State Philosophy Club in 2008, the North Carolina Philosophical Society in 2009, and the Northwest Philosophy Conference in 2011.

Relativity and Time Travel

This webpage was prompted by some useful critical correspondence with Tim Maudlin and with Jay Hodges about a webpage that was once part of this website on the physics of forward time travel. Thank you to them both. Maudlin’s “Relativity Theory” entry in Encyclopedia of Philosophy and Brian Greene’s discussion of wormhole time machines in The Fabric of the Cosmos provided the basis for our examples. This webpage was created from projects on the physics of time travel by Jason Wong, Torry Beek-Kenakin, Matt Behrhorst, Cody Melton, Kirk Brouwer, and Austin Olander. Ann Carroll created the diagrams. John Carroll compiled these many contributions and added his own perspective.

Multi-Dimensional Time

Tyler Barry (Multidimensional), and Korey Hite (Multidimensional) provided the foundation for these topic pages. Sam Harward put together several drafts of the page on multidimensional time. Sam also worked closely with me in my attempt to enrich Meiland’s model of multi-dimensional time. Alex Belt created and has maintained the original animations; he also provided the section on whether time travel in multi-dimensional time is truly time travel.

Must-See Movies

Caroline Bateman drafted the original version of the Must-See-Movies page. Victor Brozovsky provided a summary for Timecrimes. Movie poster images are from impawards.com.
