Dianna Cowern Instagram – This never-before-seen footage of Dianna was taken when we went to Mammoth California to film two videos about the expansion of the universe. Dianna is still sick and won’t return for a long time, so enjoy this science explanation like the good old days. [Health update] As of a few days ago Dianna is out of the hospital and doing a little better. She is in no way out of this, but at least she is not going down hill for now. If you want to support Dianna during her recovery, you can do so on Patreon where we post content like this more often. → patreon.com/physicsgirl #physicsgirl #diannacowern #physics #universe #universeexpanding #observableuniverse #science #scienceexplanation
