Scientific "facts" change over time. When I was younger, I visited a lot of caves. Often, when I encountered stalactites and stalagmites, I was told their age, based on their size, and the "fact" that it took hundreds of years for them to increase an inch in length. I believed it until I visited a cave in Arkansas, which had only one natural entrance. To facilitate tours, there was a man-made concrete tunnel used as an exit. There were stalactites hanging from the concrete roof of the tunnel, some of which were over four inches long.
Knowledge can be divided into three parts: what we know that we know, what we know that we don't know, and what we don't know that we don't know. The last part is by far the largest, and the easiest for the smug egotists among us to be totally unaware of. Don't be too sure of anything, and question every "fact," especially those found on Wiki-pedia.
