Someday, this web page will no longer exist. The computer on which you're viewing it will not exist; nor, indeed, will you or this planet, someday. There will be only the galaxies, silent unnamed systems, stars and planets slowly changing over unimaginable spans of time, spinning through lifeless space as the light slowly dims. Astronomy will be the last science that matters, describing the universe eons after all its inhabitants are gone, finally becoming sublimated into particle physics, to describe the end of existence. Why do we need to know? Because it's the only question it is possible for us to ask; we know no others.
