>The surface of the Earth is the shore of the cosmic ocean. On this shore we've learned most of what we know. Recently, we've waded a little way out, maybe ankle-deep, and the water seems inviting. Some part of our being knows this is where we came from. We long to return. And we can't, because the cosmos is also within us. We're "made" of star stuff. We are a way that the cosmos can know itself. The journey for each of us begins here. We're going to explore the cosmos in a ship of the imagination, unfettered by ordinary limits on speed and size, drawn by the music of cosmic harmonies. It can take us anywhere in space and time. Perfect as a snowflake, organic as a dandelion seed, it will carry us to worlds of dreams and worlds of facts. Come with me.
