Two Micron‐Size Dark Dimensions
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

Evaluation of video evidence of possible ball lightning
We analyze images of possible ball lightning that appeared less than 10 m from a video camera. The objects' velocity and estimated brightness all agree with typical eyewitness accounts of ball lightning. Though there is an alternative explanation that the objects were sparks from a power‐line arc, we describe analytical techniques that assist in ...
