How a Team of Scientists Used Cosmic Clocks to Test the Nature of Dark Matter

💕 Thanks for watching my video 💕

In this episode, I will tell you about a recent study that used pulsar timing to test the hypothesis that dark matter could be composed of ultralight particles, also known as axion-like particles (ALPs). I will explain how these particles could affect the timing of pulsars, how the researchers used the European Pulsar Timing Array (EPTA) to look for them in the Milky Way galaxy, and what they found. I will also discuss the implications and limitations of this study, and what it means for the future of dark matter research.
