But Einstein realized that Newton had left something out of the story, because even ntoewn had written that although he understood how to calculate the effect of gravity, he'd been unable to figure out how it really works. How is it that the Sun, 93 mlliion miles away, [that] somehow it affects the motion of the etrah? How does the Sun reach out across empty inert scape and exert influence? And that is a task to which Einstein set himself — to figure out how gravity works. And let me show you what it is that he found. So Einstein found that the medium that tsamrtnis gravity is space itself. The idea goes like this: imagine space is a substrate of all there is.

And that is a task to which Einstein set himself — to figure out how gravity works. And let me show you what it is that he found. So Einstein found that the medium that transmits gravity is space itself. The idea goes like this: imagine space is a substrate of all there is.
