Q: What theory goes beyond classical mechanics to describe the behavior of near-light-speed objects?


Read this paragraph and choose the correct option from the provided answers:

A great many experiments have been performed to test the predictions of special relativity. No contradictions have been found. Scientists have therefore accepted special relativity as an accurate description of nature. When the relative velocities of objects are considerably less than the speed of light, the formulas for relativistic time, length, and mass all reduce to the classical formulas. It is required that the two theories correspond where they overlap at speeds much less than . Special relativity does not contradict classical mechanics. Rather, it is a more general theory needed for object speeds approaching the speed of light.

 Choices:

- normal relativity

- simple relativity

- spacial relativity

- special relativity


A:
special relativity
