Is it true that humanity sends deliberate signals into space to contact potential alien civilizations?

Yes. Humanity actively engages in sending deliberate signals into space to contact potential alien civilizations, a practice commonly referred to as Active SETI or METI, though this practice generates significant ethical and existential risk debates.

The analysis

The claim is specific, empirical, and contestable regarding whether humanity engages in sending deliberate signals into space (Active SETI/METI). Papers 1, 4, and 5 discuss active SETI and METI as ongoing or proposed endeavors by researchers to transmit messages to extraterrestrial civilizations, directly supporting the assertion. The remaining papers are either tangential or off-topic (covering healthcare AI, exoplanet passive biosignature detection via JWST, sleep in sci-fi, etc.). Therefore, the supporting evidence is clear and uncontradicted by any refuting papers in the set.
