Question: Which of the following statements is true about time dilation?

Options:

1. Time moves slower for objects moving at high speeds compared to stationary observers.
2. Time moves faster for objects in strong gravitational fields.
3. Time is unaffected by speed or gravity.
4. Time dilation only occurs in quantum systems.

Correct Answer: Time moves slower for objects moving at high speeds compared to stationary observers.

Solution:

Time dilation is a consequence of Einstein\'s theory of relativity, indicating that time passes more slowly for objects moving at speeds close to the speed of light compared to stationary observers.
