Space travel: Stephen Hawking and billionaire's plan for laser-propelled nanocraft fleet

The video discusses a futuristic concept of sending nanocrafts to Alpha Centauri using a star chip equipped with a light sail. These nanocrafts would be propelled by a powerful laser array located in the Atacama Desert. The goal is to achieve 20% of the speed of light, allowing the nanocrafts to reach Alpha Centauri in decades, a journey that would take current spacecraft thousands of years.
