In TIME AND THE TECHNOSPHERE Argüelles shows that in order for us to survive and not destroy Earth's ability to sustain life we must change our definition of time and adopt a natural harmonic calendar based on the 13-moon 28-day cycle. Humanity deviated from this natural time 5000 years ago. The creation of the 12-month Gregorian calendar and the 60-minute hour of the mechanical clock has subjected us to the artificial 12:60 time frequency that governs the entire global industrialised civilisation - the technosphere. With the collapse of the Twin Towers a fissure was created in this artificial technosphere opening up the noosphere (Earth's mental envelope). It is the signal that history is ending and we are running out of time - artificial time. Humanity's last best chance to adopt this natural view of time and step into the bright new future promised by the galactic shift of 2012 is the Great Calendar Change of 2004. This startling new discovery is based on the author's continued mathematical research into the Mayan calendar showing the clear distinction between third-dimensional astronomical time and the fourth-dimensional synchronic order of the Law of Time. · Reveals September 11 as the signal of the end of artificial time according to the Law of Time. · Long awaited sequel to the author's best-selling book The Mayan Factor. · Explains the Great Calendar Change of 2004 and its enormous potential for the future of humanity.
