Riggs, Peter J. – Physics Education, 2019
Despite being established as genuine physical features of the universe, black holes are not well understood at a non-technical level. Basic features of black holes are outlined, a few of the more popular misconceptions surrounding them are listed and their errors identified.

Kontomaris, Stylianos Vasileios; Malamou, Anna – Physics Education, 2018
Black holes and the physics behind them is a fascinating topic for students of all levels. The exotic conditions which prevail near a black hole should be discussed and presented to undergraduate students in order to increase their interest in studying physics and to provide useful insights into basic physics concepts, such as non-uniform…

Pinochet, Jorge – Physics Education, 2019
Given the great interest that black holes arouse among non-specialists, it is important to analyse misconceptions related to them. According to the author, the most common misconceptions are that: (1) black holes are formed from stellar collapse; (2) they are very massive; (3) they are very dense; (4) their gravity absorbs everything; and (5) they…

Matney, Gabriel; Lustgarten, Alyssa; Nicholson, Taylor – Investigations in Mathematics Learning, 2020
In this study, we share our broad and deep search for what is known from blind-peer-reviewed research publications about the efficacy of the instructional practice of Number Talks. We describe our process for literature review and the subsequent analysis that revealed a shallow depth of articles for which one can discern the factors of quality of…

Pinochet, Jorge – Physics Education, 2018
In 1974, Stephen Hawking theoretically discovered that black holes emit thermal radiation and have a characteristic temperature, known as the "Hawking temperature." The aim of this paper is to present a simple heuristic derivation of the Hawking temperature, based on the Heisenberg uncertainty principle. The result obtained coincides…

Andersen, W. L. – Physics Teacher, 2020
It often falls to a physicist to teach a conceptual astronomy course. It is easy to justify a treatment of general relativity in the context of massive stars, black holes, and cosmology. There are a number of good books available to serve as texts or references, including Thorne's "Black Holes and Time Warps: Einstein's Outrageous…

Pinochet, Jorge – Physics Education, 2020
In this paper we present a simple dimensional analysis exercise that allows us to derive the equation for the Hawking temperature of a black hole. The exercise is intended for high school students, and it is developed from a chapter of Stephen Hawking's bestseller "A Brief History of Time."

Falla, David – School Science Review, 2012
The nature of light and how it is affected by gravity is discussed. Einstein's prediction of the deflection of light as it passes near the Sun was verified by observations made during the solar eclipse of 1919. Another prediction was that of gravitational redshift, which occurs when light emitted by a star loses energy in the gravitational field…

Nagbe, Mariama N. – Texas Education Review, 2019
Centering the role of institutional racism within graduate education remains an understudied topic in existing literature on Black doctoral student socialization experiences at Predominantly White Institutions (PWI). This leaves us with a void of sorts--or a Black (w)hole--whereby numerous studies acknowledge challenges within the collective Black…

Draper, Ciara; Houghton, Jack; Read, Beth; Bird, Danny; Tatten, J. J. – FORUM: for promoting 3-19 comprehensive education, 2016
This article is written by young people who attend an open-access youth project in the city centre of Hull. Although they describe themselves as "educational failures" (the "black holes"), they argue that they have a significant contribution to make to discussions about how to develop socially just education in schools. In the…

Ruiz, Michael J. – Physics Teacher, 2008
An introductory approach to black holes is presented along with astronomical observational data pertaining to the presence of a supermassive black hole at the center of our galaxy. Concepts of conservation of energy and Kepler's third law are employed so students can apply formulas from their physics class to determine the mass of the black hole…

Roy, Arunava – Physics Teacher, 2011
The European Center for Nuclear Research or CERN's Large Hadron Collider (LHC) has caught our attention partly due to the film "Angels and Demons." In the movie, an antimatter bomb attack on the Vatican is foiled by the protagonist. Perhaps just as controversial is the formation of mini black holes (BHs). Recently, the American Physical Society…

Huggins, Elisha – Physics Teacher, 2018
Consider the fall of the apple that, by legend, hit Newton on the head. Instead of using this to introduce Newton's law of gravity, we will discuss the point of view that the fall of the apple was caused by a minuscule curvature of spacetime in the region surrounding Newton and the apple tree. We will calculate this curvature using concepts and…

Pinochet, Jorge – Physics Education, 2020
Einstein's theory of general relativity (GR) provides the best available description of gravity. The recent detection of gravitational waves and the first picture of a black hole have provided spectacular confirmations of GR, as well as arousing substantial interest in topics related to gravitation. However, to understand present and future…

Augousti, A. T.; Gawelczyk, M.; Siwek, A.; Radosz, A. – European Journal of Physics, 2012
The problem of communication between observers in the vicinity of a black hole in a Schwarzschild metric is considered. The classic example of an infalling observer Alice and a static distant mother station (MS) is extended to include a second infalling observer Bob, who follows Alice in falling towards the event horizon. Kruskal coordinates are…
