NOT A REPLACEMENT. “Note that while the emergent theory in classically safe regions (far away from not only high curvature, but even curvature giving rise to event horizons) must be compatible with general relativity, it is allowed to be more detailed, e.g. fitting within the diffeomorphism invariance of general relativity.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

A CONSEQUENCE. “The simplest example of a direct consequence is in settings where flat space-time is a good approximation and general relativity would not distinguish between regions with vacuum vs a presence of obstacles to information flow.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

“GIFTED CHILDREN have three atypical characteristics: " "#1. They are precocious" "#2. They learn differently from typical children (marching to their own drummer)" "#3. They are intensively motivated to learn (showing a rage to master)” https://lnkd.in/etxXcuFe View in LinkedIn

FLUCTUATING SPACE-TIME. “With vacuum, we here mean empty space-time where only quantum fluctuations are present, and the optionally present obstacles are extended objects made of matter, not sufficiently massive to prevent flat space-time from be a good approximation on the scales considered.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

FLAT SPACE-TIME. “General relativity would not make a distinction between these two scenarios since it is a theory of curvature only.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

INFORMATION FLOW. “However, any model based on information exchange must depend on how information is transmitted through regions, and so a presence vs absence of obstacles to information flow must give qualitatively different results for the space-time configuration.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

RELATIVE GEOMETRY. “With information propagation restricted due to matter, the shortest path is around rather than across an obstacle. This property of information exchange implies non-trivial structure of the associated flat space-times, relative to the case without obstacles. We will call this relative geometry, and model it on the connectivity of flat space-time, leaving dt constant.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

FLAT SPACE-TIME. “If an obstacle describing a surface extending only through a fraction of the region is placed within the region, an information origin of space-time would mean a bending of the light rays around the surface edges, relative to the reference frame set by the vacuum behaviour.” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn

BENDING LIGHT. “This would happen since the surface would describe an ‘insulating’ surface (using the temperature analogy) in terms of the interactions present, which would be cut off in one space dimension along the surface (the object).” https://link.springer.com/content/pdf/10.1007/JHEP07(2019)140.pdf View in LinkedIn
