Archaeology is a deeply conservative discipline and I have found that archaeologists, no matter where they are working, have a horror of questioning … - Graham Hancock

Very often these luminous designs, rich in data, take the form of geometry. I speak from experience, having participated in more than seventy ayahuasca sessions since 2003, continuing to work with the brew for the valuable lessons it teaches me long after Supernatural was researched, written, and published. Here's part of my account of the first time I drank ayahuasca in the Amazon: I raise the cup to my lips again. About two thirds of the measure that the shaman poured for me still remains, and now I drain it in one draught. The concentrated bittersweet foretaste, followed instantly by the aftertaste of rot and medicine, hits me like a punch in the stomach…. Feeling slightly apprehensive, I thank the shaman and wander back to my place on the floor…. Time passes but I don't keep track of it. I've improvized a pillow from a rolled-up sleeping bag and I now find I'm swamped by a powerful feeling of weariness. My muscles involuntarily relax, I close my eyes, and without fanfare a parade of visions suddenly begins, visions that are at once geometrical and alive, visions of lights unlike any light I've ever seen — dark lights, a pulsing, swirling field of the deepest luminescent violets, of reds emerging out of night, of unearthly textures and colors, of solar systems revolving, of spiral galaxies on the move. Visions of nets and strange ladder-like structures. Visions in which I seem to see multiple square screens stacked side by side and on top of each other to form immense patterns of windows arranged in great banks. Though they manifest without sound in what seems to be a pristine and limitless vacuum, the images possess a most peculiar and particular quality. They feel like a drum-roll — as though their real function is to announce the arrival of something else.13 Other notes I made following my ayahuasca sessions in the Amazon refer to a "geometrical pulse,"14 to "a recurrence of the geometrical patterns,"15 to "a background of shifting geometrical patterns,"16 and

[The cosmic impact that started the Younger Dryas] marked the end of their story, and the end of an epoch, really. There's not a single Clovis point found anywhere in North America that's above that black mat. They're all in it or below it. And there's not a single mammoth skeleton anywhere in North America that's above it. A huge part of the die-off could have been as a direct result of the impacts themselves, but impacts and airbursts south of the ice cap, particularly as far south as New Mexico, would also have set off wildfires. There's overwhelming evidence that gigantic wildfires raged at the onset of the Younger Dryas — in fact, more soot has been found at the Younger Dryas Boundary than at the Cretaceous-Paleogene Boundary. We did the calculations and it looks like as much as 25 percent of the edible biomass and around 9 percent of the total biomass of the planet was on fire and destroyed within days or weeks of the YDB. So in many areas if the animals weren't killed outright they wouldn't have been able to forage enough food afterwards to survive. The grass would have burned up, leaves on trees were gone. ... And you know, the other thing is that when comet fragments come in they're traveling incredibly fast and they literally punch a hole in the atmosphere. They actually push the air aside and they bring in that super cold from space, and when they explode in the air that cold plume continues to the ground and you literally have things frozen in place if they were close enough to where the plume came down. It's possible they were fried and then frozen all within a matter of seconds.

Professor Napier and his colleague Victor Clube, formerly dean of the Astrophysics Department at Oxford University, go so far as to describe the 'unique complex of debris' within the Taurid stream as 'the greatest collision hazard facing the earth at the present time.' Coordination of their findings with those of Allen West, Jim Kennett, and Richard Firestone, as led both teams — the geophysicists and the astronomers — to conclude that it was very likely objects from the then much younger Taurid meteor stream that hit the earth around 12,800 years ago and caused the onset of the Younger Dryas. These objects, orders of magnitude larger than the one that exploded over Tunguska, contained extraterrestrial platinum, and what the evidence from the Greenland ice cores seems to indicate is an epoch of 21 years in which the earth was hit every year, with the bombardments increasing annually in intensity until the fourteenth year, when they peaked and then began to decline before ceasing in the twenty-first year.
