Vahagn "Vahe" Gurzadyan (Armenian: Վահագն Գուրզադյան; born 21 November 1955) is an Armenian mathematical physicist and a professor and head of Cosmology Center at Yerevan Physics Institute, Yerevan , Armenia, best known for co-writing "Concentric circles in WMAP data may provide evidence of violent pre-Big-Bang activity"[1] paper with his colleague, Roger Penrose, and collaborating on Roger Penrose's recent book Cycles of Time.

Gurzadyan has suggested and initiated the use of Compton Edge method for high accuracy testing of the light speed isotropy and the Lorentz invariance at GRAAL experiment in European Synchrotron Radiation Facility (Grenoble); the obtained limit became a reference number for Special Relativity extension models.

That concept includes the hypothesis that the Universe can be full of traveling extraterrestrial life streams as low-complexity compressed bit strings at von Neumann automata network.

He led a study with geneticists in Duke University introducing a new method to detect somatic mutations in genomic sequences,[21] in proposing bath-quantum system viewpoint on the relation of thermodynamic and cosmological arrows of time.

as the earliest known image of that comet[25] He revealed the observation of supernova SN 1054 (progenitor of Crab nebula) in Armenian medieval chronicle of Hetum (Hayton of Corycus) and Cronaca Rampona.
