How Space and Time Could Be a Quantum Error-Correcting Code


John Preskill, a theoretical physicist at the California Institute of Technology, says quantum error correction explains how space-time achieves its “intrinsic robustness,” despite being woven out of fragile quantum stuff. “We’re not walking on eggshells to make sure we don’t make the geometry fall apart,” Preskill said. “I think this connection with quantum error correction is the deepest explanation we have for why that’s the case.”The language of quantum error correction is also starting to enable researchers to probe the mysteries of black holes: spherical regions in which space-time curves so steeply inward toward the center that not even light can escape. “Everything traces back to black holes,” said Almheiri, who is now at the Institute for Advanced Study in Princeton, New Jersey. These paradox-ridden places are where gravity reaches its zenith and Einstein’s general relativity theory fails. “There are some indications that if you understand which code space-time implements,” he said, “it might help us in understanding the black hole interior.”

Quantum Magazine again, these folks are on top. Error correction happens when Plank's action counts are coherent around an 'axis' of symmetry.  The 'axis' becomes our space/time marker.

Blac Holes are interesting in that physicists are beginning to believe that extreme compression makes more spectral axis f symmetry, and this is all a result of sphere packing behavior, which can be constructed via mathematics and the known compression constant.  Another outcome is that Avogadro's number is a mathematical constant for our universe.

Einstein knew that space does not divide by zero so there has to evolve extra axes of symmetry such that the vacuum can respond.   There is o other way, as near as i can tell.
