Are Newtonian physics universal?

Click For Summary
SUMMARY

Newtonian physics operates effectively within specific bounds, particularly for everyday objects, but fails to apply universally, especially at relativistic speeds. While Newtonian mechanics can describe interactions accurately at lower velocities, they do not account for relativistic effects that become significant as objects approach the speed of light. Astrophysics confirms that these limitations are critical in understanding the broader universe, indicating that while Newtonian principles are objective, they are not universally applicable.

I am wondering if things can be objective but not universal.

What do you mean by "things"?
Is a coffee mug objective? How about universal?
 
As far as we know and can tell (through astrophysics) Newtonian physics work well enough within certain bounds. We know Newtonian physics doesn't work well at all for objects traveling close to the speed of light. We know also that even at reduced velocities there are relativity effects on "Newtonian" interactions, they are just too small in magnitude to make a practical difference.
