João Magueijo

João Magueijo ( * 1967 in Évora ) is a Portuguese theoretical physicist who is a representative of a cosmological theory with a variable speed of light ( see superluminal ) known.

Magueijo studied physics at the University of Lisbon and was at Cambridge University (St. John 's College ) PhD. After that, he was at Princeton University and Cambridge University and is a professor at Imperial College London.

In 1998, he developed a cosmological theory with a variable speed of light (Variable Speed ​​of Light Theory, VSL) with Andreas Albrecht. Increased in the early universe the speed of light could be the horizon problem and other cosmological problems can be solved without inflation. A similar theory was proposed by John Moffat in 1993, but at first largely ignored ( there was also a priority dispute with Moffat, but the both amicable attached any ). Magueijo 2003 published a popular book about his theory.

He also published a biography of Ettore Majorana.
