The Journal of Higher Dimensional Physics was a 21st-century human scientific journal. Volume 49, published in 2079, contained an article on pages 264-575 about a discovery in quantum physics by Tobias Shaw and Wallace Fujikawa. This was later retconned, as both these men are later noted to have been born in the 23rd century, so it likely does not exist in proper Bungie canon.
- The actual Shaw-Fujikawa Translight Engine was created much later, or there is a possible continuity error, as Shaw and Fujikawa are later noted in Halo: Contact Harvest to have built the Shaw-Fujikawa Slipspace Drive in the year 2291.
- The volume number is a 7 reference, in that 49 is 7x7.
