That&#x27;s both true and not. Yes, it&#x27;s true that the point is akin to saying that even though we have the equations to understand fluid dynamics we don&#x27;t understand the weather more than in a rough general way and aren&#x27;t able to make predictions ahead of a few measly days. But it&#x27;s also true that even the theory behind it isn&#x27;t &quot;true&quot; in the absolute sense. We don&#x27;t have a renormalizable quantum field theory of gravity. Therefore our current understanding is most certainly incomplete, much in the same way Newtonian physics alone wasn&#x27;t complete in its description of phenomena.
