我们人类不过是高等灵长类生物，生活在一颗小星球上。我们生活的银河系之外，有上亿颗星球。然而，自人类文明诞生以来，人类就没有停止过对世界根本规律的探索。宇宙的边界是什么？肯定有个特别的答案，但是还有比没有边界更特别的答案吗？同样，人类的潜力也不会有边界。我们都是与众不同的。无论生活多么艰辛，你总会有自己的方式发光。 生命不息，希望不止。 -----霍金\n It is clear that we are just an advanced breed of primates on a minor planet orbiting around a very average star, in the outer suburb of one among a hundred billion galaxies. But ever since the dawn of civilization, people have craved for an understanding of the underlying order of the world. There ought to be something very special about the boundary conditions of the universe. And what can be more special than that there is no boundary? And there should be no boundary to human endeavor. We are all different. However hard life may seem, there is always something you can do and succeed at. While there is life, there is hope.\n ——Steven Hawking
