Dark matter is often thought of as the glue that holds the Universe together. With five times as much gravity due to this unseen form of matter as compared to normal, atom-based matter, it affects how galaxies and giant large-scale structures form in a tremendous, truly epic way. But depending on what the properties of dark matter actually are, we should get a very different Universe on smaller scales.

Is dark matter cold? Warm? Hot? And does it interact with itself, or is it truly invisible? Thanks to a fascinating new technique, we're learning more about this than ever before. Take a listen as we invite Dr. Anna Nierenberg onto the podcast to talk about how gravitational lensing is revealing dark matter substructure as never before, and how it might reveal these elusive properties of dark matter at long last as a result.
