Dr. Becky Smethurst discusses the research of astrophysicists trying to understand the conflict between observations of galaxies and their supermassive black holes and the current best model of the Universe. There are over 1 billion galaxies in the Universe, each home to over a billion stars and one central supermassive black hole weighing in at up to a billion times the mass of the Sun. Scientists think that these supermassive black holes can either heat or remove the cold hydrogen gas within a galaxy needed to form new stars through a huge outburst of energy. However, astronomers have never actually observed this process happening in our Universe.
Dr. Becky Smethurst is an astrophysicist at the University of Oxford and star of astronomy-themed YouTube channel Dr. Becky, where each week she explains either an unsolved mystery, a weird object found in space or discusses general space news. Her debut public science book Space: 10 Things You Should Know was named one of Sky at Night magazine’s top 20 books of 2019. In the book, Smethurst composed ten captivating, simple essays, which guide you swiftly through the galaxies, explaining the mysteries of black holes, dark matter and what existed before the Big Bang. It makes us wonder whether we really are alone, illuminates what we still don’t know, and much more.
