Physicists are moving closer than ever to finally reconciling quantum physics with gravity, while elsewhere, mysterious shapes and 'positive geometry' are offering clues to unifying quantum physics and cosmology. Also, a mysterious phenomenon that causes rocks to move across Death Valley's sands on their own has been unraveled by engineers at Virginia Tech. Finally, this strange physics mechanism enables objects to "levitate" on Sunlight.
Here's a look at these stories, and others we're covering right now at The Debrief:
