Cold Quasars: The Death of Galaxies with Dr. Allison Kirkpatrick

What are quasars?
Are Black Holes Really Black?

Dr. Allison Kirkpatrick, astrophysicist at the University of Kansas, recently announced her discovery of cold quasars a new object in the field of astronomy — galaxies featuring an abundance of cold gas that can produce new stars despite having a quasar at the center. The breakthrough finding overturns assumptions about the end state of galaxies and may represent a phase of the death of a galaxy that was previously unknown. John Michael Godlier spoke to Dr. Kirkpatrick about this discovery as well as the future of the Milky Way galaxy and its eventual merger with Andromeda. Discussing if we will need to worry about a future where our galaxy becomes a quasar and earth possibly becomes in the path of a blazar. As well as how supermassive black holes collide, if black holes are really black and how black holes can get ejected due to collisions and wander through the universe unseen.
