Throughout history, many have embarked on the quest to discover the answers to the
fundamental mystery concerning the ultimate origins of the universe and the purpose of our …

Theoretical physics and foundations of physics have not made much progress in the last few
decades. Whether we are talking about unifying general relativity and quantum field theory …

We address the question of whether it is possible to operate a time machine by manipulating
matter and energy so as to manufacture closed timelike curves. This question has received a …

The view that the laws of nature produce later states of the universe from earlier ones
(prominently defended by Maudlin) faces difficult questions as to how the laws produce the …

Here, we outline the basic structure of relativistic spacetime and record a number of facts.
We then consider a distinction between local and global spacetime properties and provide …

This Element provides a somewhat comprehensive interpretation of general relativity, a
description of what reality would be like if the theory were true. This concerns (i) what …

One usually identifies a particular collection of geometric objects with the models of general
relativity. But within this standard collection lurk 'physically unreasonable'models of …

Kerr spacetimes are a family of exact solutions to the vacuum Einstein's field equations
which can be used to represent the exterior of a spinning body, in particular a rotating black …

Abstract We investigate Kerr–Newman black holes in which a rotating charged ring-shaped
singularity induces a region which contains closed timelike curves (CTCs). Contrary to …
