João Magueijo (born 1967) is a Portuguese cosmologist and professor in Theoretical Physics at Imperial College London. He is a pioneer of the varying speed of light (VSL) theory.
João Magueijo studied physics at the University of Lisbon. He undertook graduate work and Ph.D. at Cambridge University. He was awarded a research fellowship at St John's College, Cambridge, the same fellowship previously held by Paul Dirac and Abdus Salam. He has been a faculty member at Princeton and Cambridge, and is currently a professor at Imperial College London where he teaches undergraduates General Relativity and postgraduates Advanced General Relativity.
In 1998, Magueijo teamed with Andreas Albrecht to work on the varying speed of light (VSL) theory of cosmology, which proposes that the speed of light was up to 3×1030 km/s in the early universe. This would explain the horizon problem (since distant regions of the expanding universe would have had time to interact and homogenize their properties), and is presented as an alternative to the more mainstream theory of cosmic inflation.
