What's Dark Matter? - Tumble Science Podcast for Kids

What this episode covers

What is dark matter? Why do scientists think it exists? How are they searching for it, and why are they doing it in an underground lab?! Join us on the search for dark matter with Alvaro Chavarria, a physicist running a dark matter detector underneath a mountain in the French Alps. We’ll take you inside the lab to visit the detector, and find out why everything we think we know about dark matter… could be wrong. For more, visit our website!
