But to get there requires a radical reshaping of Einstein’s General Theory of Relativity. The new idea is called Shape Dynamics, and it just may be our future theory of gravity. Instead, he recasted Einstein’s famous equations using another language, called Shape Dynamics. Shape Dynamics focuses on the relationships between objects, rather than the spacetime, the unified fabric of space and time, that they sit in. It’s not exactly clear yet if these differences invalidate Shape Dynamics.
