Which outcome occurs when an observer inside a freely-falling elevator measures the trajectory of a laser pulse?

💡 Explanation

The observer detects no gravitational force internally because Einstein's equivalence principle states acceleration and gravity are indistinguishable; therefore, free-fall eliminates detectable gravity locally, rather than the light curving or its speed changing.
