What came before the Big Bang remains a mystery but new tools may help



London, UK (SPX) Aug 21, 2025
A team of physicists is arguing that one of the biggest taboos in cosmology-asking what existed before the big bang-can now be approached using numerical relativity. In a new paper published in Living Reviews in Relativity, Eugene Lim of King's College London, together with Katy Clough of Queen Mary University of London and Josu Aurrekoetxea of Oxford University, describe how computer simulations can extend Einstein's equations into extreme conditions where analytic methods fail. Einstein's genera ... read more
