What does the discovery of the possibly habitable exoplanets around Trappist-1 mean? And how might this change our idea of our existence in the grand scheme of things?
We humans are naturally curious creatures — we are born to explore. A mission to Mars excites us because we simply don’t know what we’ll discover, or how exactly it will add to our knowledge, or what new technologies will arise as a result. Even if we don’t immediately sense its benefits, it still has value, because the journey of learning is its own reward.
