What was our atmosphere like 2 billion years ago?
The enigma of this glass is:
1. The amount. It is the largest known deposit of a natural silica glass, ~98% SiO2 , on Earth.
2. It's distribution. The distribution is approximately elliptical, ~130 km by ~50 km with the major axis ~NNW by SSE.
3. Physical properties. The composition and structure of the glass are consistent with a hypothesis that the glass was formed from melted desert dune sand and subsequently cooled over a period greater than 24 hours in an Earth atmosphere.
4. Fusion energy. Possibly a meteorite or comet impact, but there are no meteor craters detectable from satellite photos with a resolution of ~5m within 150 km. No Libyan Desert Glass has been found at the nearest meteorite crater, located in Libya, ~150km to the west.
5. Chemistry. The glass cannot have been fused from the local exposed sandstone.
6. Age of glass and dunes. The dune sand and dunes have been formed in a time estimated to be less than 1,000,000 years, yet the fission track dates of the glass have a mean of ~28,000,000 years.
7. Surface geology. 28,000,000 years ago some geologists estimate that the sandstone was beneath ~300m of limestone and covered with vegetation. [From: www.physics.wustl.edu...]
The architect of modern atomic bomb who was in charge of the manhattan project was asked by a student after the manhattan explosion, “How do you feel after having exploded the first atomic bomb on earth”. Oppenheimer’s reply for the question was , “not first atomic bomb, but first atomic bomb in modern times”. He strongly believed that nukes were used in ancient india. what made oppenheimer believe that it was a nuclear war was the accurate descriptions of the weapons used in the mahabharatha war in the epic which match with that of modern nuclear weapons.
Libyan Desert Glass (sometimes referred to as Egypt or Egyptian Desert Glass) is a rare and beautiful impact glass, found in only one remote location on Earth, near the Libyan/Egyptian border. It is associated with an ancient meteorite impact, which occurred somewhere in the North African deserts. Quality specimens are translucent, and also display pseudo regmaglypts, possibly caused by wind erosion, or by ablation when molten fragments were thrown into the air following impact. Perhaps the most enchanting of all meteorite-related collectibles, Libyan Desert Glass is now extremely difficult to obtain, as removing material from the site is prohibited by the Egyptian government.
The ancient pectoral pictured at left belonged to Tutankhamun, and the yellow scarab is carved from Libyan Desert Glass, giving this striking meteoritic material a unique link to Egypt and to humanity's distant past.
Strange specimens of natural glass found in the Egyptian desert are products of a meteorite slamming into Earth between 100,000 and 200,000 years ago, scientists have concluded. The glass—known locally as Dakhla glass—represents the first clear evidence of a meteorite striking an area populated by humans. At the time of the impact, the Dakhla Oasis, located in the western part of modern-day Egypt, resembled the African savanna and was inhabited by early humans, according to archaeological evidence.
"This meteorite event would have been catastrophic for all living things," said Maxine Kleindienst, an anthropologist at the University of Toronto in Canada. "Even a relatively small impact would have exterminated all life for [several] miles."
The origin of the glass had puzzled scientists since Kleindienst discovered it in 1987. Some researchers had suggested the Stone Age glass may have been produced by burning vegetation or lightning strikes. But a chemical analysis showed that the glass was created in temperatures so high that they could only have been the result of a meteorite impact. Gordon Osinski, a geologist at the Canadian Space Agency in Saint-Hubert who conducted the analysis, found that the glass samples contain strands of molten quartz, a signature of meteorite impacts.
Hair and nails fell out;
Pottery broke without apparent cause,
and the birds turned white
The total number of skeletons found at the main site of Mohenjo-Daro, during the initial archeological digging during 1922-1931, was, just 37. 14 of those, including a minor, were found inside a small room, 1 was found in a blocked lane. Let me quote Prof. G.F.Dales from his “The Mythical Massacre at Mohenjo-daro”
Nine years of extensive excavations at Mohenjo-daro (1922-31) - a city of three miles in circuit – yielded the total of some 37 skeletons, or parts thereof, that can be attributed with some certainty to the period of the Indus civilizations. Some of these were found in contorted positions and that suggest anything but orderly burials. Many are either disarticulated or incomplete….Where are the burned fortresses, the arrow heads, weapons, pieces of armor, the smashed chariots and bodies of the invaders and defenders? Despite the extensive excavations at the largest Harappan sites, there is not a single bit of evidence that can be brought forth as unconditional proof of an armed conquest and the destruction on the supposed scale of the Aryan Invasion.
Later excavation unearthed more Skeletal remains in other Indus valley ruins like Harappa, Dholavira, Lothal etc., which numbered a little more than 300. [I am not sure of the exact number.]
It is an absolute lie that bodies littered the streets of these ruins. There isn’t a shred of evidence of an instantaneous mass death, as evidenced in Hiroshima and Nagasaki. Some of these skeletons were actually buried at different ground level, pointing to different periods of time. There isn’t any evidence of any major war or invasion itself.
One of the great mysteries of classical archaeology is the existence of many vitrified forts in Scotland. Are they also evidence of some ancient atomic war? Maybe, but maybe not. There are said to be at least 60 such forts throughout Scotland.
Radiation still so intense, the area is highly dangerous
A heavy layer of radioactive ash in Rajasthan, India, covers a three-square mile area, ten miles west of Jodhpur. Scientists are investigating the site, where a housing development was being built.
For some time it has been established that there is a very high rate of birth defects and cancer in the area under construction. The levels of radiation there have registered so high on investigators' gauges that the Indian government has now cordoned off the region. Scientists have unearthed an ancient city where evidence shows an atomic blast dating back thousands of years, from 8,000 to 12,000 years, destroyed most of the buildings and probably a half-million people. One researcher estimates that the nuclear bomb used was about the size of the ones dropped on Japan in 1945.
The Mahabharata clearly describes a catastrophic blast that rocked the continent. "A single projectile charged with all the power in the Universe...An incandescent column of smoke and flame as bright as 10,000 suns, rose in all its splendor...it was an unknown weapon, an iron thunderbolt, a gigantic messenger of death which reduced to ashes an entire race.
"The corpses were so burned as to be unrecognizable. Their hair and nails fell out, pottery broke without any apparent cause, and the birds turned white.
"After a few hours, all foodstuffs were infected. To escape from this fire, the soldiers threw themselves into the river."
Historian Kisari Mohan Ganguli says that Indian sacred writings are full of such descriptions, which sound like an atomic blast as experienced in Hiroshima and Nagasaki. He says references mention fighting sky chariots and final weapons. An ancient battle is described in the Drona Parva, a section of the Mahabharata. "The passage tells of combat where explosions of final weapons decimate entire armies, causing crowds of warriors with steeds and elephants and weapons to be carried away as if they were dry leaves of trees," says Ganguli.
"Instead of mushroom clouds, the writer describes a perpendicular explosion with its billowing smoke clouds as consecutive openings of giant parasols. There are comments about the contamination of food and people's hair falling out."
Archeologist Francis Taylor says that etchings in some nearby temples he has managed to translate suggest that they prayed to be spared from the great light that was coming to lay ruin to the city. "It's so mid-boggling to imagine that some civilization had nuclear technology before we did. The radioactive ash adds credibility to the ancient Indian records that describe atomic warfare."
Construction has halted while the five member team conducts the investigation. The foreman of the project is Lee Hundley, who pioneered the investigation after the high level of radiation was discovered.
