So what exactly did happen during Interstellar's Lazarus mission? Director Christopher Nolan wrote a short comic revealing a crucial moment in Dr. Mann's story. Naturally, expect spoilers below and in the comic.
For a period of 15 days, a cooled copper mass enclosed in a cryostat container may very well have been the coldest object in the Universe. At -273.144 degrees Celsius, it nearly achieved absolute zero. The technique, which resulted a world record, could produce important new insights into exotic particle physics.
What is Absolute Zero, and does it really exist anywhere in the universe? Could we ever reach Absolute Zero in real life?
Ask scientists a question, and you might get amazing answers. Consider this video, which poses three head-scratchers: what happens to electrons at absolute zero, whatever happened to the light from the Big Bang, and are you any good at sports?
