Dr. Becky | Is the Strength of Gravity Really Constant?
Is the gravitational constant, G, really a constant? Or does it change with time, or with space, or with scale in the Universe?! And if it did, could this help solve the crisis in cosmology?! Or even be an explanation for dark energy and the accelerated expansion of the universe?
A big thanks to Dr Harry Desmond, my colleague at Oxford who is an expert on modified gravity theories, for very helpful discussion while I prepared this video.
