Hagedorn transition and chronology protection in string theory [PDF]

, 2005
We conjecture chronology is protected in string theory due to the condensation of light winding strings near closed null curves. This condensation triggers a Hagedorn phase transition, whose end-point target space geometry should be chronological ...

Volcanic dust veils from sixth century tree-ring isotopes linked to reduced irradiance, primary production and human health

Scientific Reports, 2018
The large volcanic eruptions of AD 536 and 540 led to climate cooling and contributed to hardships of Late Antiquity societies throughout Eurasia, and triggered a major environmental event in the historical Roman Empire.

Spacetime Splitting, Admissible Coordinates and Causality

, 2012
To confront relativity theory with observation, it is necessary to split spacetime into its temporal and spatial components. The (1+3) timelike threading approach involves restrictions on the gravitational potentials $(g_{\mu \nu})$, while the (3+1 ...
