Universe Today Podcast
Seeking Observational Evidence of Quantum Gravity
Theoretical physicists are focused on understanding the unification of fundamental forces by grasping the quantum nature of gravity. They aim to detect traces of quantum gravity in large-scale structures or cosmic microwave background observations. The energy scale of cosmic inflation is the highest currently observable, 5 orders of magnitude below the Planck scale where quantum gravity theories are expected to hold. String theory, as a candidate for quantum gravity, suggests the string scale is below the Planck scale, aiming for a well-behaved theory at that energy level.
