Absolute Axes and Tidal Forces

Gravitational Tidal Forces and Atmospheric Processes

Recent studies have revealed a relationship between variations in gravitational tidal forces and rainfall. A possible mode of interaction of the tidal forces on atmospheric processes is suggested to explain how the tidal forces which are small may induce detectable effects on atmospheric circulation, considering both synoptioscale and shortperiod processes in the atmosphere. The variability of ...

On D0 Brane Polarization by Tidal Forces

Gravitational tidal forces may induce polarization of D0 branes, in analogy to the same effects arising in the context of constant background gauge fields. Such phenomena can teach us about the correspondence between smooth curved spacetime and its underlying non-commutative structure. However, unlike polarization by gauge fields, the gravitational counterpart involves concerns regarding the cl...

Production of Tunguska-Sized Bodies by Earth's Tidal Forces

Tidal disruption of rubble-pile bodies (stony or icy aggregates held together by self-gravity) during close Earth encounters may produce signiicant numbers of Tunguska-sized (50 m) fragments. Using an N-body simulation to model encounters between strengthless, elongated, rotating, particulate bodies and the Earth, we found two disruption categories which produce small bodies: (a) \Shoemaker-Lev...
