Sorry, you need to take Cosmos original or Cosmos remake ... with a little more skepticism. Or do you really believe in Popular Mechanics?
I know that Ohm's law works ... have used it as an electrical engineer. I also know that it is semi-empirical ... it isn't "G-d's Truth" (TM). That is a far cry from claiming to know, know ... what happens inside a black hole, or what happened in the first few seconds of the Big Bang. Yes, scientists do know the difference between hypothesis and demonstrated theory ... but not at grant time ... they are paid by being on the bleeding, unconfirmed edge. Life by the grant, die by the grant. Publish or perish.
