The Wow! signal was a strong narrowband radio signal detected on August 15, 1977, by Ohio State University's Big Ear radio telescope in the United States, then used to support the search for extraterrestrial intelligence. The signal appeared to come from the direction of the constellation Sagittarius and bore expected hallmarks of extraterrestrial origin - but to date no one is certain.

The term "Milky Way Sagittarius" refers to the relationship between the Milky Way Galaxy and the constellation Sagittarius. The center of our galaxy - which contains a supermassive black hole called Sagittarius A* - is located within the boundaries of the Sagittarius constellation as seen from Earth. Therefore, when looking towards the constellation Sagittarius, you are also looking towards the center of the Milky Way.

Modern day simulation theory is based on creation through a black hole - which is a simplistic way to explain how realities are created at the physical level.

The "Wow!" signal has been etched with a red marker in the memory of advocates for the search for extraterrestrial intelligence (SETI) since its unveiling in 1977. To this day, it remains one of the most enigmatic radio frequency signals ever found. Now a new paper from a wide collection of authors, including some volunteers, provides some corrections, and some new insights, into both the signal and its potential causes.
