Move or stay? A Nobel laureate’s reflection on interplanetary travel

April 1, 2025

During the World Copernican Congress, Prof. Michel Gustave Mayor shared his thoughts on our position in the universe and the future of space exploration. His words are not just a scientific analysis, but also a deep reflection on a question that intrigues many: can—and should—humanity think about moving to another planet?

In a short but inspiring video, the Nobel laureate ponders the consequences of discovering thousands of exoplanets and the real possibilities of interstellar travel. Does every star have its own planetary system? Are there habitable planets? And if so, do we have any chance of ever getting there? Is the idea of an interstellar move a realistic prospect or merely an illusion? Or perhaps, instead of searching for a new home, should we focus on caring for our own planet?

This is not a lecture full of numbers and theories, but an authentic reflection of a man who changed our perception of the cosmos. We invite you to watch the debate and share your thoughts.
