Which consequence would occur to an observer inside an elevator accelerating upwards in empty space, due to Einstein's equivalence principle?

💡 Explanation

The elevator's upward acceleration creates an artificial gravitational field mimicking a real gravitational field, an effect of the equivalence principle; because the acceleration produces an apparent gravitational force, therefore an increase in the perceived gravitational field occurs, rather than changes spacetime or photons directly.
