Why does gravity make the earth round ? Brian Cox | Quantum physics

For decades, quantum gravity has been a theory-driven field, lacking direct experiments.A Stanford PhD student explains how new tabletop experiments may soon allow us to test whether gravity is truly quantum.These advances could shift our understanding of one of the most fundamental questions in physics. | Perimeter Institute | Facebook
