First of all, I would like to tell everyone that reaching the "upper levels" isn't nearly as important as finding out a way to reach within an attokelvin of absolute zero (that is about 0.000000000000000001° kelvin). However, the highest temperature we've ever gotten is 2.3 billion degrees Fahrenheit (2,300,000,000°F).
