The Earth is built to last. It is a 4,550,000,000-year-old, 5,973,600,000,000,000,000,000-tonne ball of rock and iron. It has taken more devastating asteroid hits in its lifetime than you've had hot dinners, and it still orbits happily around the sun. But physics is a curious thing – and it can harness devastating power – enough even to destroy the world… Naked Science will explore how physics could destroy a planet by exploding with 1,300,000,000,000 tonnes of antimatter, or a fission machine, being sucked into a black hole: pulverized by a cosmic impact, or hurled into the Sun. So strap in, buckle up, and enjoy the ride to doomsday.
