> [6][obsolete source]
I didn't know but apparently wikipedia treats old sources as obsolete, doesn't matter if there's new information or not that would make it obsolete.
I wonder if any sources supporting the notion that the earth is round must be updated every couple of years with a new source or study.
That exemplifies a much deeper problem than good information, “Good Law”: https://en.m.wikipedia.org/wiki/Good_law
As an aside, the earth is almost flat, just not nearly as flat as the Universe.

Obsolete doesn't just mean old, it means superseded by newer information.
