The little robot, black holes, and spaghettification
Jorge Pinochet
The tidal forces generated by a black hole can be so powerful that they cause unlimited stretching, known as spaghettification. A detailed analysis of this phenomenon requires the…
Three easy ways to the Hawking temperature
Jorge Pinochet
In this work, three heuristic derivations of the Hawking temperature are presented. The main characteristic of these derivations is their extreme simplicity, which makes them easil…
Brown dwarfs and the minimum mass of stars
Jorge Pinochet
Stars form from large clouds of gas and dust that contract under their own gravity. The birth of a star occurred when a fusion reaction of hydrogen into helium has ignited in its c…
Five misconceptions about black holes
Jorge Pinochet
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 misconce…
"Black holes ain't so black": An introduction to the great discoveries of Stephen Hawking
Jorge Pinochet
Between 1974 and 1975, Stephen Hawking revolutionized the world of physics by proposing that black holes have temperature, entropy, and evaporate gradually. The objective of this a…
The Hawking temperature, the uncertainty principle and quantum black holes
Jorge Pinochet
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 p…
Einstein ring: Weighing a star with light
Jorge Pinochet, Michael Van Sint Jan
In 1936, Albert Einstein wrote a brief article where he suggested the possibility that a massive object acted as a lens, amplifying the brightness of a star. As time went by, this…
