When an object falls into a black hole, it appears to slow down and fade from view as time slows down for the object. This is due to the extreme gravity of the black hole, which warps spacetime and causes time dilation.

time dilation
general relativity

  • As an object approaches a black hole, time slows down from the perspective of an outside observer, and the object appears to freeze at the event horizon.
  • Einstein's general theory of relativity replaced Newton's concept of gravity with the idea that masses curve spacetime, causing other objects to follow curved paths.

Insights from the YouTube Video Script:

1. Why Can't We See Objects Enter a Black Hole?

The script explains that although we can't directly observe objects crossing the event horizon, we can still infer their fate. The light emitted from the object gets increasingly redshifted and dimmed as it approaches the event horizon, eventually fading from view. This is because the object's time slows down from our perspective, and the emitted light is stretched to longer wavelengths.

2. The Black Hole's 'Frozen Image': A Paradox?

This video tackles a seemingly contradictory concept: how an object falling into a black hole appears frozen in time at the event horizon. This is due to the extreme
