New proof reveals how Quantum Matter interacts with gravitational fields. This no-go theorem sets the constraints for Quantum Gravity theories, showing that if quantum matter influences a gravitation.

Have you ever pondered the mysteries of the universe? Specifically, the mind-bending realm where quantum mechanics and gravity intersect? Well, buckle up, because a recent paper by Thomas Galley, Flaminia Giacomini, and John Selby is about to take us on a fascinating journey into this enigmatic world. Their research provides a formal proof, a sort of 'cosmic detective work,' revealing new insights about the behavior of quantum matter when it flirts with gravitational fields.
