  • Albert Einstein revolutionized physics with his theory of relativity, which changed how we understand space and time.
  • Einstein's theory of relativity
  • general theory of relativity

Morphology

theory + of + relativity

The phrase is a straightforward noun phrase built from 'theory' (a set of ideas) + 'of' (genitive/linking preposition) + 'relativity' (the concept that space and time are relative). A B1 learner who knows these constituents can directly infer that it names the scientific theory about relativity, and the same compositional pattern exists across many languages, so it is immediately comprehensible.

Etymology

The name theory of relativity comes from the simple idea that measurements like time and distance change with your situation: imagine one person on a fast train and another on the platform watching the same clock and seeing different times. So it means 'a scientific idea that time and space depend on the person watching', which is why the word relativity is used.
