About this listen
In this episode, we explore the most dangerous object in the universe. While there are many dangerous cosmic entities like black holes, neutron stars, and supernovas, the most powerful and destructive is a quasar. A quasar is a supermassive black hole at the center of a galaxy, surrounded by a disk of gas and matter. As the black hole consumes this matter, it emits immense amounts of energy, sometimes outshining entire galaxies.
We also touch on pulsars—rapidly spinning neutron stars that emit pulses of radiation—but they are not nearly as destructive as quasars. Fortunately, the nearest quasar is 800 million light-years away, and most likely no longer exists. However, a new quasar could form in the distant future when the Milky Way collides with the Andromeda galaxy. While these objects are far from us now, the unpredictability of the universe keeps us in awe of what could happen billions of years from now.
