B
The speed of light is constant regardless of the observer's motion.
C
Different observers experience time based on their individual emotional states.
D
Gravity affects the flow of time only near black holes.
Understanding the Answer
Let's break down why this is correct
Answer
In Einstein’s Theory of Relativity, the speed of light is always the same for everyone, no matter how fast you or the light source are moving. Because light’s speed is fixed, a moving clock must run slower so that the light still travels at the same speed for all observers. This means that if two observers are moving relative to each other, each will see the other’s clock ticking more slowly. For example, a spaceship traveling close to the speed of light will experience less time than people on Earth, so its clock will lag behind an Earth‑bound clock. This difference in perceived time is the primary reason why observers in relative motion perceive time differently.
Detailed Explanation
The speed of light is constant for all observers, no matter how fast they move. Other options are incorrect because Some think time never changes, but relativity shows it changes with motion; Feelings don't change the clock hands.
