Researchers have made a breakthrough in photonic crystals that could revolutionize the development of interstellar space missions. Known as Starshot, the project aims to develop laser-propelled spacecraft that could reach Alpha Centauri, our nearest stellar neighbor, in just 20 years.

The breakthrough in photonic crystals is a major step forward for the Starshot project. Photonic crystals are extremely efficient at storing and transmitting light energy, meaning they could be used to power spacecraft with laser propulsion. This could potentially allow spacecraft to travel faster than ever before, and make interstellar travel a reality. The research team is now working to develop a prototype of the photonic crystals, which could be tested in a laboratory setting.
