The episode discusses how verses from the Quran appear to reference the sun eventually using up all its fuel and expiring in the future. It discusses scientific research showing that the sun generates heat through nuclear fusion, which can only last as long as it has hydrogen to fuse into helium. Eventually the sun will run out of hydrogen fuel and the nuclear reactions will stop, causing the sun to die. The episode cites sources like NASA and National Geographic documentaries discussing how the sun will grow hotter and expand as it ages, evaporating oceans and destroying life on Earth before collapsing into a white dwarf. It argues this shows remarkable knowledge about the sun's life cycle and expiry was revealed in the Quran over 1400 years ago.
