Recent theoretical and observational advances have revitalised the study of black holes endowed with scalar fields. Traditionally, the no‐hair theorem suggested that black holes could be fully ...

Scientists typically explain gravity in terms of Einstein’s theory of general relativity. In this model, objects in the universe cause the fabric of spacetime to warp around them, creating a ...

Philosophers of physics should be more attentive to the role energy conditions play in General Relativity. I review the changing status of energy conditions for quantum fields-presently there are no ...

Students learn to distinguish between scalar and vector quantities. Introduction to Vectors: Students learn to distinguish between scalar and vector quantities and how to state the magnitude and ...

The theory of the representation of wave fields in terms of superpositions of monochromatic plane waves is presented for fields satisfying the inhomogeneous scalar wave equation. The discussion ...
