Invisible robots overshadowed by metallic hydrogen

After much coffee and a lot of crispy bacon, the second day of the APS March Meeting began. The hot topic of the day – metallic hydrogen. Even though we arrived 15 minutes early to Isaac Silvera‘s talk, the crowd was overflowing from the room, but despite all the pushing and shoving (my foot has not recovered from being stood on), we did manage to get seats. Silvera began by saying that he had been working on the problem for “probably longer than [most of us] were born” before taking us through the nearly 45 years of research on the subject. He also gave a press conference that included talks by theoretical physicists David Ceperley from the University of Illinois and Jeffrey McMahon from Washington State University. My colleague Tushna Commissariat caught up with Silvera later on, so be on the lookout for a more detailed update from her.
