Maybe we will find something digital in light. However, the way light affects and interacts with matter forms may also be a clue to a breakthrough in SETI search.

Statistically, we CAN'T be alone, and from all the biological molecules we are finding in space, I believe we have no bottom line justification for believing we are alone.

The plain GR fact is that life elsewhere in the universe is well aware of our existence, and probably has good ways of getting "action at a distance" when and if it wants to.

Stranger than science fiction it is- and probably as true as the experimental veracity of GR.

Best wishes in your search!
