Before famed physicist Stephen Hawking passed, he financially backed the Breakthrough Listen Initiative, essentially a large telescope trying to detect alien signals. Another major source of funding for the SETI program is Mark Zuckerberg, founder of Facebook.
Those who believe the search for extraterrestrial life is a worthy one, however, may be excited to hear that the telescope that the Breakthrough Listen Initiative utilizes just got an upgrade, which will greatly increase its coverage of the cosmos and (apparently) chances of finding alien life.
Could it be that alien signals have in fact been detected, but that they end up being classified?
Perhaps Mark Zuckerberg is getting plenty of return on his investment. Perhaps the Breakthrough Listen Initiative is actively monitoring alien life in our solar system, rather than searching for it?
