Welcome to the discussion group, Kratos Aurion.
Please state your evidence and rationale. How did you determine those specific dates? The galactic center is 30,000 light-years away, meaning even if its black hole could travel at the speed of light (it can’t) it would take 30,000 years to get here.
Regarding the video, there is no “clear” connection between the Mayan development of a calendar and real physical events. Their science was only advanced enough to create a calendar. They only produced calendars that would serve up to a particular date, but that hardly implies the end of the world or other calamities. Even if it was supposed to, how would they know such a thing? Most modern calendar makers don’t produce any to be used beyond the end of the following year, but that does not imply frightful events to follow.
Passage through the galactic plane results in virtually no gravitational effect on bodies in the solar system. Ignore authoritative sounding announcers, pseudo-researchers, sensationalistic writers, zealous video producers or ancient texts. Some folks will stoop to anything to earn a buck. Science does not depend on the voice of authority, but on solid evidence tied into a rational theory. That video was produced by the kind of charlatans who prey on credulous woos who “want” to believe in scenarios that sound cool or scary.
