Newtonisen

Newtonisen is a hypothetical concept in theoretical physics that explores a potential departure from Newtonian mechanics under extreme conditions or within certain theoretical frameworks. It is not a formally recognized scientific theory or established physical law but rather a speculative idea that arises when considering the limitations or extensions of classical physics. The term itself is a neologism, combining "Newton" with a suffix suggesting a deviation or alternative.

The core idea behind Newtonisen is to imagine a scenario where the fundamental principles of Newtonian mechanics, such as inertia, action-reaction, and universal gravitation, no longer hold true or are significantly modified. This could occur in regions of extremely high spacetime curvature, such as near black holes where general relativity becomes dominant, or in speculative theories of quantum gravity where classical concepts might break down. Some theoretical physicists might use the term informally when discussing thought experiments that push the boundaries of our current understanding of gravity and motion.

It's important to distinguish Newtonisen from established theories like Einstein's theory of relativity, which has been experimentally verified and accurately describes gravity and motion at high speeds and in strong gravitational fields. Newtonisen is not a replacement for relativity but rather a conceptual tool for contemplating the unknown or the extremely unconventional. Its existence or relevance would depend entirely on future theoretical developments and experimental discoveries that might reveal physics beyond our current models.
