Universality: This is the most basic assumption, some books even do not include it as one of the principles. We assume that the physical laws we discovered on or near the Earth can be applied to anywhere in the universe.

 


Universality Class
This is a way of classifying the behavior of systems near the critical points of continuous phase transitions.

Universality
The assumption that the physical laws observed on earth apply throughout the universe.

Universality of physical laws: The same pattern of hydrogen lines are seen in the in spectra of the Sun, stars, distant galaxies, and quasars (active galaxies at very great distances from us).

Universality (philosophy)
In philosophy, '''universalism''' is a doctrine or school claiming universal facts can be discovered and is therefore understood as being in opposition to relativism....

The universality of free-fall only applies to systems in which gravity is the only acting force. All other forces, especially friction and air resistance, must be absent or at least negligible.

The universality (or otherwise) of the extinction curve makes a huge difference for how strongly we can correct for dust effects.

This caused justice to be increasingly associated with equality and universality, which in Europe saw an emergence of the concept of natural rights.

Due to its long reach and universality, however, gravity shapes the structure and evolution of stars, galaxies, and the entire universe.

That is the concept of Universality, which basically says the laws of physics are the same everywhere, which means that if gravity behaves a certain way here, it should behave the same way elsewhere in the Universe.

Because of this universality, gravity is believed to be a manifestation of the curvature of space-time caused by matter and energy, and is described by the Einstein Equation of General Relativity.

The Big Bang theory depends on two major assumptions: the universality of physical laws, and the cosmological principle. The cosmological principle states that on large scales the Universe is homogeneous and isotropic.

Systems in the same universality class have the same behavior in the critical region, when an appropriate matching is made between the physical variables, and have the same critical exponents. [D89]

However, later study challenged the universality of the successive capture theory. No element was found to have a stable isotope with an atomic mass of five or eight.

Kepler's laws opened the way for the development of celestial mechanics, i.e., the application of the laws of physics to the motions of heavenly bodies. His work shows the hallmarks of great scientific theories: simplicity and universality.
