On the Counter-Rotation of Closed Time-like Curves

Universe, 2022
While it is tempting to think of closed time-like curves (CTCs) around rotating bodies, such as a black hole, as being “caused” by the rotation of the source, Andréka et al.

A new approach to the temporal significance of house orientations in European Early Neolithic settlements.

PLoS ONE, 2020
This paper shows that local differences in house orientation in settlements from the Early Neolithic in Central Europe reflect a regular chronological trajectory based on Bayesian calibration of 14C-series.
