C.S.Lewis

Universe in a black hole.

The spaceship in the image is approaching Earth at a speed faster than light.

From Earth's perspective, the spaceship appears to suddenly materialize before our eyes as if it has teleported, and then it seems to move backward, as if time is being reversed. In other words, it looks like the spaceship is receding from Earth.

This occurs because the light capturing the spaceship passing through point B reaches Earth before the light capturing the spaceship passing through point A.



If an object approaches at a speed faster than light, its image would suddenly appear before our eyes and then seem to recede gradually. This is due to the time delay in the information reaching our eyes.


Therefore, inside a black hole, the universe may appear to be expanding. The gravity of a black hole pulls in everything, including light, so the universe we observe may be distorted by the way information propagates from beyond the event horizon. 

This suggests that the universe we see could be an illusion of events that occurred in the past.
