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!

What have you been listening to this week? You don't need to do a 6000 word review if you don't want to, but please write something! If you've just picked up some music, please update on that as well, we'd love to see your hauls :)

Feel free to give recs or discuss anything about each others' listening habits.

For those interested in making masks to wear in nonclinical settings or for personal use, Kaiser Permanente offers step-by-step instructions and an accompanying how-to video. Even homemade masks need to meet certain specifications in order to be effective. Please, if you are sharing the community masks you are making with others, masks should be washed before wear.

This is a recurring post to discuss programming or other technical projects that we've been working on. Tell us about one of your recent projects, either at work or personal projects. What's interesting about it? Are you having trouble with anything?

This is an image which contains spoilers for the entirety of The Last of Us 2, proceed at your own risk

A major cutscene also got leaked. This is a link to that cutscene. Proceed at your own risk.

It seems that QA testers were promised bonuses when the game was going to launch, but with the indefinite delays, those bonuses obviously got pushed back. Considering that the menu language of the cutscene is Portuguese (I think), I wouldn't be surprised if someone from South America, where QA probably got outsourced to (Naughty Dog is infamous for their bad work culture) was depending on that bonus, especially with the covid situation.

I don't know how to handle this situation discussion-wise right now. If you want to spoil yourself for whatever reason (maybe not planning on buying the game, whatever) and discuss the plot of TLOU2, please mark everything as spoilers (you can use sections to hide sensitive info). Everyone else, tread lightly.

EDIT: Actually, a lot more cutscene got leaked, here's the links in the section:
