The actual world changes may take many years to fully play out, as this will be more of a process than a one-time event, but they may well include worldwide disclosure of extraterrestrial presence, a release of the free energy and healing technologies that have been suppressed by corporations for so long, a complete restructuring of the financial system to make it much more equitable, release of advanced antigravity vehicles (currently known as UFOs), and with all of that, an effective end to world hunger, disease, war, and environmental destruction.
