A cadre of international scientists plans
an updated transmission to extraterrestrials:
binary code beamed by waves of radio
[universal across all intelligence levels];
mathematica simplex: zero/one, black/white, yes/no—
and this is how the message ran:
– Bases, binary and decimal; prime numbers + the largest prime
– Mathematical operations |add, subtract, multiply, divide|
– Most common elements |carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur|.
– Deoxyribonucleic structures
– Solar system’s position using globular clusters
– Physics of particles
– Algebraic articles
– Earth composition and characteristics
– Different trademarks humanistic
– Position of Earth in solar depiction
– Geographical survey
– Exponential operations
– An invitation to reciprocate

Not the first intentional heavenly missives;
a century of casting out unintentionals—
just reaching the shallows: not even a nibble.
