Well, we are constantly proving ourselves wrong, and making new discoveries every day using science. Of course I'm taking in a general sense, because the scientific process across many different fields/professions. It doesn't necessarily mean it's wrong, but shows that there's something more than we can explain.
I would like to ask, in your opinion, what makes science better? I believe that most science expands upon what we already know (better science), although there have been a few examples where a commonly accepted scientific theory has been proven to be flat-out wrong (great science).
Of course it's a contradiction, authority is to be trusted yet taken with a grain of salt. Usually the argument from authority is a logical fallacy when said authoritarian figure is attempting to step out of their bubble of authority. Now that you have me thinking about this, I may be wrong, as it seems that Tyson, as a scientist has now stepped into the realm of beliefs.
