Time Cube was a pseudoscientific personal web page set up in 1997 by Otis Eugene "Gene" Ray.

[6] Adi Robertson of The Verge commented that Ray's theory of time is "an incredibly confusing one peppered with racism and homophobia".

Ray spoke about Time Cube at the Massachusetts Institute of Technology in January 2002 as part of a student-organized extra-curricular event during the independent activities period.

"[9] Ray also spoke about Time Cube at the Georgia Institute of Technology in April 2005, delivering a speech in which he attacked the instruction offered by academics.

[13][14] The song "To the End of the World" on Alestorm's 2017 album No Grave But the Sea makes several references to the Time Cube concept.
