I heard this in a science lecture.
Is this a correct use of the word "never"? I'm not a native English speaker, but for me, "never" means we know that there's is no point in time (past, present or future) when it is true. "Until" means that there may be a point in the future when something changes from false to true (or vice versa). From that standpoint, "never" means that there can be no "until", or am I missing something?
