The Theory of Everything is the second studio album by Life On Planet 9, the pseudonym used by American hard rock band Lo-Pro when releasing music of a more experimental sound.

Lead singer Pete Murray and guitarist Neil Godfrey first began working with each other in the late 1990s for the nu metal band Ultraspank.

The band found themselves with some material that was more centralized around acoustic guitar and electronic effects than Lo-Pro's hard rock sound.

[8] Progress would be slow though, as Murray and Godfrey would concurrently be working on their 2013 Lo-Pro release, Disintegration Effect, and participating on the Battlefield of the Mind project, where they collaborated with members of Staind and Megadeth.

[9][10] Murray and Godfrey would refocus their efforts in mid-2013, with them stating that they were about 75% complete with the album as of August 2013, and done with all but one track by the end of the year.
