• Resumen

  • The article discusses research on a unified theory of physics that links gravity and particle physics. A July 2010 meeting of mathematicians and physicists is noted wherein attendees discussed principles that were used during the so-called golden age of particle physics in the 1960s. Physicist Murray Gell-Mann is cited regarding Lie groups of elementary particles. An overarching Lie group incorporating gravity was theorized at the time, but not defined. It is noted that string theory came into favor in the 1980s for determining a unified theory of physics. A model presented at the meeting by physicists Roberto Percacci and Fabrizio Nesti is noted.
