However, in extreme cases like black holes and the Big Bang, we need a theory that includes both. For example, in a black hole, gravity is so strong that all matter collapses into a single point. To understand this, we must see how gravity behaves at the quantum level.
This is where the new study could help. “Our approach is that space and time themselves are not continuous but consist of small portions. If this thesis is correct, then gravity can also be described with the help of quantum theory,” Wolfgang Wieland, study author and a theoretical physicist at the Friedrich-Alexander University of Erlangen-Nuremberg (FAU), said.
