Final answer:
There is no definitive evidence that order will always be uncovered in new explorations of physics. While the laws of physics provide a simplifying view of nature, complex systems can behave unpredictably and may not always reveal a clear underlying order.
Step-by-step explanation:
The question deals with the underlying simplicity and unity in nature, as observed through Newton's laws of motion and gravity, and whether such order can be expected to always be found in new explorations of the physical world. While Newton's laws, among other discoveries, highlight the order in nature, there is no definitive proof that such order will invariably be discovered in future explorations of complex systems.
Moreover, new fields like complexity science are revealing that, while simple laws of physics apply, complex systems may show emergent behaviors not seen in simpler systems. Thus, while we have made great strides in understanding the physical world through the laws of physics, predicting that order will always emerge from complexity is not guaranteed.
In summary, the nature of scientific inquiry and the history of physics suggest a pattern of uncovering underlying order, but as complexity increases, so does the potential for chaotic and unpredictable behaviors, which cannot be definitively argued to always result in order.
