Explore quantum gravity at your level of expertise, from accessible overviews to cutting-edge research
Quantum gravity represents one of the most profound challenges in modern physics: how to unite Einstein's theory of general relativity with quantum mechanics. These two pillars of 20th-century physics have been extraordinarily successful in their respective domains, yet they seem fundamentally incompatible when we try to combine them.
This incompatibility becomes critical in extreme environments like black holes or the first moments after the Big Bang, where both quantum effects and strong gravitational fields are important. Understanding quantum gravity could unlock the deepest secrets of space, time, and the nature of reality itself.
Beyond fundamental physics, quantum gravity research is beginning to inspire practical applications through quantum sensing technologies. These emerging connections hint at future breakthroughs in medical imaging, biological sensing, and our understanding of life itself at the quantum scale.
