All we know is all we know, and with each moment we know more; therefore, we never know.
We predict future particulars based on general “laws,” but those laws are based on past particulars. We can confidently state that mammals never lay eggs till we see our first platypus.
So, because there's always more to be revealed, anything's possible—we could turn out to be mistaken about everything. Once the terror wore off, that might be exciting.
