Kepler conjecture
Summary
The Kepler Conjecture is a famous mathematical problem first proposed by the astronomer and mathematician Johannes Kepler in 1611. It asks a simple question: What is the most efficient way to pack identical spheres, such as oranges, marbles, or cannonballs, so that they take up the greatest possible amount of space? Kepler believed that the familiar arrangement used by fruit sellers and cannonball stacks—where each sphere sits in the gaps of the layer below—is the densest possible packing, filling about 74% of the available space.
Although the idea seems obvious from everyday experience, proving it mathematically turned out to be extraordinarily difficult and remained unsolved for nearly 400 years. In 1998, mathematician Thomas Hales finally produced a computer-assisted proof, which was later fully verified through a formal proof project completed in 2014. The Kepler Conjecture is a great example of how a question inspired by everyday objects can lead to some of the deepest and most challenging work in mathematics.
