The anomalies of the heterotic string in the semi-light-cone gauge can be removed by adding suitable local order ℏ terms to the local Weyl and spacetime (rigid) Lorentz transformation rules. The resulting quantum transformation rules exactly satisfy the spacetime Lorentz algebra. This removes the...
In practice, all event horizons appear to be some distance away from any observer, and objects sent towards an event horizon never appear to cross it from the sending observer's point of view (as the horizon-crossing event's light cone never intersects the observer's world line). 實際上...
“Making Things See” could be the the beginning of a ‘light-switch’ moment for everyday things with behaviour hacked-into them. For things with fractional AI, fractional agency – to be given a fractional sense of their environment. ...
The Chimp presents estimates based on gravity and inertia, but even those are little more than guesses thanks to wormhole corruption of the local spacetime. We’re stretched across the probability wave, waiting for the box to open so the universe can observe whether we’re dead or alive. ...
Sometime following her return from the Dalek Asylum, Amy gave up her modelling career. Ten months after their last adventure, The Doctor materialised the TARDIS around Amy, Rory, and Rory’s father, Brian, who were repairing a light in Amy and Rory’s living room. The Doctor took them, ...

. . = 1, 2 denote the two sets of spacetime spinors. We will often write expressions in so(4)1 × so(4)2 notation. so(4)1 corresponds to rotations along the AdS3 × S3 directions transverse to the light-cone directions t and φ. This is not a symmetry of the theory; ...
