After much deliberation, Robin has an explaination for the ending of 2001: A Space Odyssey.
The journey through the tunnel of light symbolises the hero’s passage into the afterlife. He then finds himself in a room where he acts as a guinea pig. He ages quickly and, on his deathbed, sees the black monolith before him: God! He then flies back to earth as a baby in a capsule, as a “starchild”: this is reincarnation/Buddhism, the reason behind everything is the black monolith.
“I also believe that God looks like this and doesn’t have a white beard.”
