Relativistiche

Relativistiche is the Italian plural adjective meaning relativistic. It is used in Italian-language texts to describe theories, models, or effects that arise from or require the theory of relativity.

In physics, relativistic phenomena become relevant when speeds approach that of light or when gravitational fields are strong, making Newtonian mechanics inadequate. The concept covers both the special relativity and general relativity frameworks.

Key ideas include Lorentz invariance, the constancy of the speed of light, time dilation, length contraction, and energy–mass equivalence, as well as the curvature of spacetime described by general relativity.

Applications span particle physics, astrophysics, cosmology, and technologies that rely on relativistic corrections, such as satellite navigation systems. The term also appears in philosophy of science discussions comparing relativistic perspectives with non-relativistic approximations.
