There's a way to study what galaxies are made of by having a very bright light behind the galaxy, like really far away. And looking at how that light bends around inside that galaxy andlike how the light fluctuates as things move. Called gravitational micro lensing in this case, the kind of thing I'm working on,. It's where you have black holes pulling matter into themselves so they make an incredibly bright light which we can see across the universe.
Stars. Black holes. THE GAWDANG UNIVERSE. Astrophysicist and cosmologist Katie Mack (@astrokatie) joins to tell us her most embarrassing moments as a cosmologist, to debunk some physicist myths and give the nuts + bolts of everything form particle physics to gravitational waves and existential mysteries. Walk away with cocktail party comprehension of everything from the itty-bitty quarks that make you to the neutron stars banging together across the cosmos. More than anything, get perspective about your life on this, our little pale blue dot.
