What Is Trying To Contact Us From Space?🪐追加:
Unexplained signals have been detected from deep space. In 1977, the Wow signal lasted 72 seconds and matched what scientists expect from a non-natural radio source. Fast radio bursts can release more energy in milliseconds than the Sun produces in several days. Some [music] of these signals originate from regions with no visible stars or galaxies. Certain signals repeat at exact intervals, including one detected every 22 minutes for months. Known sources like magnetars explain some signals, but others do not match any current model. Is something [music] calling us? Many signals appear once and are never detected again. With no confirmed explanation, a repeating signal requires a source, but not all sources have been found. The Wow signal, what do you think?
