The Single Monad Model of the Cosmos and Duality of Time Theory
by Mohamed Haj Yousef
The science of Time is a noble science, that reveals the secret of Eternity. Only the Elites of Sages may ever come to know this secret.
This is called the First Age, or the Age of ages, from which time is emerging.
Ibn al-Arabi [The Meccan Revelations: Volume I, page 156. - Trns. Mohamed Haj Yousef]
About Mohamed Haj Yousef
Mohamed Haj Yousef is an author, researcher and translator whose work connects physics and cosmology with philosophy and Ibn al-Arabi’s account of time and creation. His research developed into the Single Monad Model of the Cosmos and the Duality of Time Theory.
He studied solid-state physics at Aleppo University, received his MPhil from Cambridge in 1992, and completed his PhD at Exeter in 2005. His teaching record spans undergraduate physics, electronics and laboratory instruction.
Recent work includes journal papers on completion, real commutants, quantum phase selection and temporal asymmetry. His wider publications include authored books, translations, biographical studies and a comparative book chapter.

The Single Monad Model of the Cosmos
The Single Monad Model develops the question of how a changing and apparently extended world can arise from a common generative source. It grew out of the author’s study of time, creation and unity in Ibn al-Arabi’s cosmology.
The historical foundation appeared in Ibn ‘Arabî — Time and Cosmology (Routledge, 2007). The later Single Monad series develops the interpretation through questions of renewed creation, spatial readout, quantum structure and physical response.

The Duality of Time Theory
DTT distinguishes inner generation from outer completion: the generative activity that produces a configuration and the completed record available to an observer. Six inner levels describe nested functional roles; the seventh, outer level describes completion.
The programme investigates how this distinction can be connected to geometry, clocks, phase, matter and measurement. The research directory distinguishes the published mathematical constructions from wider physical interpretations and continuing open questions.
