Paper states 234 stars' signals probably from ETIs

Chances are it's not aliens. Anomalous signals from space have been detected before and turned out to be false alarms. One occurrence was in the 1960s when satellites designed to detect Soviet nuclear explosions on Earth and near-Earth space picked up huge radiation signatures from distant stars thought to be evidence of an interstellar war in the far reaches of space which led to the discovery of pulsars. One exception was the so-called "Wow Signal" picked up on radio telescopes in 1977 which has so far remained unexplained. In SETI, the Search for Extraterrestrial Intelligence, as in any other scientific investigation, specific protocols exist for anything to be proven as fact. Empirical evidence has to be repeatable through various means and confirmed by different scientists, of which these signals have yet to be done. But it would be pretty amazing if we did tap into some galactic federation's communications network, though.
