I mean this is nothing new, this was basically the Karl Popper's answer to "the problem of induction" introduced by Hume, and scientists since Galileo were pretty much already doing this independently.
And the sun goes up, why? Because of the tilting of the Earth and the fact that the Earth revolves around the sun. If we try to understand this inductively, then how would we know that it will continue forever? This was the "problem of induction" proposed by Hume, that "the future doesn't resemble the past". We could also add: "The unseen doesn't resemble the seen", and "The distant doesn't resemble the near".
