Introduction

There are about 10^22, or ten thousand billion billion stars in the known Universe. The edge of the visible Universe is over 40 billion light years away. Radio transmissions from Earth have reached only about 100 light years since we began broadcasts. There are only about 15,000 stars within that distance from Earth. As far as we know, nothing can travel faster than light.
