Recent research by a team from the University of Sydney has uncovered evidence for the extra-terrestrial origin of Australia's most famous tourist destination. Test holes drilled at various places around the rock's perimeter and on top, revealed a layer of metamorphic sandstone averaging 1.7 metres in depth, beneath which, was a carbonaceous chondrite mass. Radar imaging demonstrated the rock was a rough sphere about 5 kilometres in diameter, with a fused crust.
Intensive research was undertaken to explain why the rock did not explode at its estimated impact speed of 30km/sec. An amazing discovery was made. A pattern of deeply buried anomalies which showed up in the multiple ultrasonic scan demonstrated that there had been not one, but three impacts about 800 million years ago.
The Ayers Rock Massif was preceded by two objects of similar size much in the manner that Comet Shoemaker-Levy impacted on Jupiter. The second object, virtually at the focal point of the impact site, was rapidly decelerated, landing at a mere few metres per second, and thus retaining its dimensional integrity. The bowl then filled in with sedimentary sand, and eventually hardened to sandstone.
Hundreds of millions of years of erosion then lowered the topography by 4 kilometres so the rock emerged from its sandstone prison to appear as we see it today.
Microbiologists from the University of New South Wales theorise that the event may have coincided with the well-known mass-extinction of pre-bacterial single-celled demi protoplasms that had formerly inhabited what was Western Australia during the pre-pre-Cambrian period.
