A cadre of international scientists plans

an updated transmission to extraterrestrials:

binary code beamed by waves of radio

[universal across all intelligence levels];

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.
