Generally, dark energy and dark matter are regarded as separate entities, but recent astronomical observations have spurred scientists to look further into a less widespread idea — that the two are in fact physically intertwined. On this episode of The Quanta Podcast, host Samir Patel speaks with Physics Editor Kathryn Jepsen about the theories surrounding dark energy’s ties to dark matter and the possibility of a shared dark universe. This topic was covered in a recent story [https://www.quantamagazine.org/a-dark-dimension-could-link-two-of-the-universes-great-unknowns-20260622/] for Quanta Magazine.   Each week on The Quanta Podcast, Quanta Magazine editor in chief Samir Patel and Senior Editor Hannah Waters speak with the people behind the award-winning publication to navigate through some of the most important and mind-expanding questions in science and math.
