A fun-filled discussion of the big, mind-blowing, unanswered questions about the Universe. In each episode, Daniel Whiteson (a Physicist who works at CERN) and Jorge Cham (a popular online cartoonist) discuss some of the simple but profound questions that people have been wondering about for thousands of years, explaining the science in a fun, shorts-wearing and jargon-free way.

How can we, humans, look at our relationship to nature differently? In season three of Going Wild, on top of stories about animals, we invite you to journey through the entire ecological web — from the tiniest of life forms to apex predators — alongside the scientists, activists and adventurers who study it. Wildlife biologist and host Dr. Rae Wynn-Grant has been studying wild animals in their natural habitats all over the world for years. Our award-winning podcast takes you inside the hidde ...

Flash Forward is a show about possible (and not so possible) future scenarios. What would the warranty on a sex robot look like? How would diplomacy work if we couldn’t lie? Could there ever be a fecal transplant black market? (Complicated, it wouldn’t, and yes, respectively, in case you’re curious.) Hosted and produced by award winning science journalist Rose Eveleth, each episode combines audio drama and journalism to go deep on potential tomorrows, and uncovers what those futures might re ...

Early Black Holes Formed Before Stars?

One of the unexpected realities of JWST is the discovery that we have really been asking the wrong questions in many astronomy areas. For instance: we generally asked how supermassive black holes and galaxies formed, with a basic assumption that these things happened in some interrelated process. We thought stellar mass black holes came from stars and that there might have been tiny primordial black holes that evaporated away, but that was it. Closed case. Black holes formed with all the normal structures we experience today. Except that now, JWST’s observations require us to find a way to accelerate the formation of those structures, and one way to do that is to seed the universe with black holes.
