Great Questions Form Thanks for your interest in PlanetTrek. One of the features of PlanetTrek will be a set of one hundred thought-provoking questions, engraved on plaques, distributed in groups of ten near the site for the Sun and each of the nine planets. Each plaque will offer an incisive question of not more than a dozen words. We need your help in coming up with appropriate questions for the plaques. Here are the guidelines: Ideally, a Great Question will be deep enough to stimulate thought about our universe, our place in it, science, life, art, philosophy, or other issues of broad human significance. It will have no obvious answer for at least the next 10 years, and may cover any area of human culture. The idea is to get parents and children, teachers and students, scientists and artists... friends and strangers, EVERYBODY, who explores PlanetTrek, to start thinking and talking with each other, to reflect on nature, our home "pale blue dot" of a planet, and all its environs, history, and future. We want visitors to come away from PlanetTrek with a deeper appreciation of the wonders of life in the universe! We hope to receive far more than a hundred suggestions. Later we will face the challenge of selecting ones to actually use. We look forward to receiving your suggestions! Entries selected for use will be duly credited.
