Calling an event "random" does not mean its causeless. It simply means its not predicable. Its not predicable because we don't know and/or haven't measured the relevant causes. Hence, Black Swan events are caused.
Perhaps it would be an interesting and profitable exercise to look for and measure causes of Black Swan events.
So long as people continue to confuse explanation with description-we'll have confusion. Math is description; science is description with comparison and the contrasting of said description(s).
Then what is explanation? I have no clue but to say it is part of consciousness, and,in the case of homo sapiens, partial consciousness.
To say that us(humans) with our four dimensional rules of calculation & perception can "know" the how of everything is no more proposterious than to believe the earth is flat.
Put another way-scientists who too often reject a new theory put forth that challenges current theories or assumptions-it reminds me of religious zealots defending any challenge to their dogma
