Immaterial artifacts in deep space

Non-exhaustive list of intangible proof of our presence into interstellar space:

  • an ever-growing Earth-centered electromagnetic bubble created in the early 50’s (radio and television broadcasts, telescopes, radar and nuclear explosions pulses, etc.);

  • brief radio messages we’ve beamed to the stars since the 60’s and also known as Active SETI (Active Search for Extraterrestrial Intelligence) or METI (Messages for Extraterrestrial Intelligence) broadcastings.

As these immaterial artifacts are travelling at the speed of light, they are the furthest witnesses of our existence, way beyond our solar system. However and despite their strength, the signals will gradually faint.

Over 45 immaterial artifacts have been identified.
