Hi all,
I am a PhD student focusing in cosmology. I wanted to up the science content here on Tildes, and I thought that one way to do so is to have an informal little Q&A session. As such, feel free to use this post to ask any questions you might have about cosmology specifically, and physics in general.
This may not be as exciting as some other science AMAs given that I am a rather early graduate student, so there may be a lot of questions I don't know the answer to. However, I'm willing to try my best and answer over the next few days, and to let you know I don't know if I don't!
A bit about myself: I did my undergraduate degree at the University of Chicago where I studied physics and mathematics, and then I was a student researcher in a computational cosmology group at a national lab. I subsequently enrolled at UC Davis to continue studying cosmology. Ask me anything about physics, cosmology, or high performance computing!
I also invite anyone else with expertise to chime in as well!
