The Latest 3I/ATLAS Developments Two days from now, on October 29, the mysterious object 3I/ATLAS will reach its closest approach to the Sun—making this a critical moment for observation and analysis. Kaku has publicly stated that if, as it whips around the Sun, 3I/ATLAS “picks up excess energy,” that would be a signal that intelligent Interstellar object 3I/ATLAS nears the Sun on October 29. Dr. Michio Kaku warns if it picks up excess energy it could point to intelligent guidance.
