    1. Has anyone else gone down the weather rabbit hole recently?

      I was always familiar with tornadoes living close to or in Oklahoma for a vast majority of my life. However, with the odd weather patterns we’re seeing this year producing severe weather, I’ve...

      I was always familiar with tornadoes living close to or in Oklahoma for a vast majority of my life. However, with the odd weather patterns we’re seeing this year producing severe weather, I’ve gone way down the rabbit hole. Watching weather livestreams, subscribing to chasers, the works. Has anyone else been on the bandwagon?

      Ok ok disclaimer, I am a cosmology PhD candidate, don’t have the degree yet. However I do feel comfortable at this point calling myself a cosmologist (I think for the first time ever). In any case, with all the new people here, I think an AMA might be fun. I will try my best to answer all of the questions I get asked, but it may not happen quickly!

      A bit about my research. I study the conditions in the early universe, specifically when the cosmic microwave background was forming, and I use CMB data to test our understanding of this era. The CMB formed roughly 300,000 years after the big bang, when the universe was 1/1000th its current size. The patterns that we see in the temperature fluctuations of the CMB can tell us a lot about the universe at this early time, and specifically we can try to use them to see if anything ‘unexpected’ happened at this time, like a hitherto undiscovered particle annihilating into ‘normal’ particles (for example).

      Ask me anything about the early universe, or physics writ large, and I will do my best to answer!
