I think a loop of cosmic string will like wiggle around and make gravitational radiation and disappear into nothingness. And if you have a cosmic string between you and some distant galaxy, then you might see two pictures of that galaxy because it like splits the space kind of. So how much do you let this kind of get to your own existence? It's not very often but every once in a while I'll be thinking about this stuff and I'll be like oh my god, like there's stuff is out there. We cannot comprehend this stuff. The earth is really tiny and really unimportant like in a big way.
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.
