96 | Lina Necib on What and Where the Dark Matter Is

The past few centuries of scientific progress have displaced humanity from the center of it all: the Earth is not at the middle of the Solar System, the Sun is but one star in a large galaxy, there are trillions of galaxies, and so on. Now we know that we're not even made of the same stuff as most of the universe; for every amount of ordinary atoms and other known particles, there is five times as much dark matter, some kind of stuff we haven't identified in laboratory experiments. But we do know a great deal about the behavior of dark matter. I talk with Lina Necib about why we think there's dark matter, what it might be, and how it's distributed in the galaxy. The latter question has seen enormous recent progress, especially from high-precision measurements of the distribution of stars in the Milky Way.

Lina Necib received her Ph.D. in physics from the Massachusetts Institute of Technology. She is currently a Sherman Fairchild Postdoctoral Scholar in Theoretical Physics at Caltech, and will be an Assistant Professor of Physics at MIT starting in the fall. Her research spans issues in particle physics and astrophysics, especially concerning the nature and distribution of dark matter, as well as techniques for detecting it and constraining its properties.

The human brain does a pretty amazing job of taking in a huge amount of data from multiple sensory modalities -- vision, hearing, smell, etc. -- and constructing a coherent picture of the world, const...

The philosophy of mathematics would be so much easier if it weren't for infinity. The concept seems natural, but taking it seriously opens the door to counterintuitive results. As mathematician and ph...
