Mastery Challenge: The Falling Astronaut
6 / 6
Let's test your understanding. Imagine an astronaut falling into a black hole. From their perspective, they cross the event horizon without noticing anything special locally. But from your perspective, watching from a safe distance, you see something else. As they approach the horizon, their time appears to slow down drastically. They never seem to actually cross it; instead, they appear to freeze and fade away. This is the ultimate consequence of gravitational time dilation.
