Voyager即将进入星际空间 (NASA)

Some people note that the chance of aliens finding the Golden Record is fantastically remote. The Voyager probes won’t come within a few light years of another star for some 40,000 years. What are the odds of making contact under such circumstances?

On the other hand, what are the odds of a race of primates evolving to sentience, developing spaceflight, and sending the sound of barking dogs into the cosmos?

Expect the unexpected, indeed.
