Gravity is no longer a mystery to physicists—at least when it comes to large distances. Thanks to science, we can calculate the orbits of planets, predict tides, and send rockets into space with precision. However, the theoretical description of gravity reaches its limits at the level of the smallest particles, the so-called quantum level.
"To explain the Big Bang or the interior of black holes, we have to understand the quantum properties of gravity," explains Professor Johanna Erdmenger, Chair of Theoretical Physics III at the University of Würzburg (JMU) in Bavaria, Germany.
"At very high energies, the classical laws of gravity fail. Therefore, our goal is to contribute to the development of new theories that can explain gravity at all scales, including at the quantum level."
