Description
In general relativity, space-time coordinates are meaningless due to immense symmetry. This leads to confusion, even for Einstein. A key property is that dynamics are generated by a surface integral, analogous to measuring electric charge via flux. This boundary Hamiltonian governs observables, implying boundary unitarity and impacting the black hole information paradox. #GeneralRelativity #Physics #Einstein #BlackHoleParadox #Cosmology Full Podcast with physicist Ted Jacobson: https://youtu.be/3mhctWlXyV8
