Universal-Cycle Tomography: a causal boundary model and its limits
The archived source is available to read.
Read the source01 / THE QUESTION
Editorial guideCan the rope-and-hairs proposal, a boundary drive read by attached sensors, recover hidden coordinates such as delay, depth or source count from measurements?
02 / WHAT THE RECORD SAYS
Source passageA calibrated source and a restricted, correct response model can allow delay estimation and prediction at frequencies not used for fitting. An arbitrary unknown source and arbitrary response functions cannot supply unique hidden coordinates.
03 / LIMITS & OPEN POINTS
Source passageAll observations in this laboratory are synthetic. No physical experiment or observation of additional dimensions is claimed.
04 / THE NEXT QUESTION
Source passageThe next empirical step is a defined physical system with a calibrated actuator and synchronized sensors.
05 / CHECKS IN THE RECORD
Source passageThe next empirical step is a defined physical system with a calibrated actuator and synchronized sensors. Specify the propagation law, admissible attachment responses, noise model, and competing models before fitting. Vary the input deliberately, fit on one set of trials, and predict withheld frequencies or time sequences without refitting. Use physically justified bounds on delay, gain, and local response; retain alternative parameterizations that remain observationally equivalent.
