Space Message
This message was transmitted from Earth into outer space toward four stars each about 60 light-years away. If you start at the top and scan down slowly, you will recognize the pattern and be able to read it:
This message is almost entirely data, with the last line being the only information about us, which soon became out of date.
What makes the last line so telling, and why does it have to be updated continuously, probably forever?
