I found that reference on a scientific journal, not my textbook. Specifically, Nature.

Regardless, they can't measure that high, and only estimate. Which is likely going to be inaccurate. Plus, Vsauce did a vid about how past a certain temperature, heat may becomes nothing more than pure energy. An "absolute hot," so to speak. Logically, think about it. How likely is it that any amount of space can reach that temperature? And how logical is it to believe that it damaged nothing? Heat is a very fluid energy, and expands rapidly.
