Light, delayed: The Shapiro Effect and the Newtonian Limit
Markus Pössel
The Shapiro effect, also known as the gravitational time delay, is close kin to the gravitational deflection of light that was the central topic of our Summer School. It is also an…
The Shapiro time delay and the equivalence principle
Markus Pössel
The gravitational time delay of light, also called the Shapiro time delay, is one of the four classical tests of Einstein's theory of general relativity. This article derives the N…
Relatively complicated? Using models to teach general relativity at different levels
Markus Pössel
This review presents an overview of various kinds of models -- physical, abstract, mathematical, visual -- that can be used to present the concepts and applications of Einstein's g…
The expanding universe: an introduction
Markus Pössel
An introduction to the physics and mathematics of the expanding universe, using no more than high-school level / undergraduate mathematics. Covered are the basics of scale factor e…
Gravitational waves and cosmic expansion: similarities and differences
Markus Pössel
Gravitational waves and cosmic expansion are both described in terms of Einstein's general relativity. This article explores the similarities between the two phenomena, as well as…
