The only knowledge I have of physics and chemistry is what I learned in high school so I apologize if my understanding is wrong. When I was in my sophomore year of high school, I was talking to my physics/chemistry teacher, and I had read somewhere the night before that light turns into a liquid at 0 kelvin. I asked if it was possible, and he said, “That does sound like it could be a possibility, but what I do know for sure is that there are a lot of very very strange things that happen at that temperature.” He said it pretty seriously and ominously and I haven’t thought about it until now. What are those strange things he’s talking about? #science source
