In the film 2001: A Space Odyssey, one of the opening scenes show a group of cavemen shrieking and yelling at a black stone monolith that also appears at the end of the film, appearing to a man on his deathbed. When I first saw this film, at the time I never looked for any deeper meaning behind symbols in popular media, and I found the appearance of the monolith to be strange and out of place. Later I came to understand that the monoliths appear just before a great revelation to or jump in the evolution of mankind.
The movie was made in 1968. On a quick side note, a monolith showed up in a park in Seattle on New Year’s Day 2001, only to mysteriously disappear three days later.
Years before this mysterious event (1992), the Millennium Hilton Hotel was opened. It faced adjacent to the WTC, and anyone who followed synchromysticism at the time would be inclined to think it would bear witness to a revelation in the year 2001.
The year 2001 will forever be remembered for the attacks of 911. The television brought us horrible images of falling towers and people running from debris.
