‘Brazilian Atlantis’: Scientists discover traces of sunken continent under Atlantic Ocean

Granite formed on dry land has been discovered beneath the ocean off the coast of Brazil. Scientists suggest that it might be part of a sunken continent which disappeared millions of years ago and already branded it ‘Brazilian Atlantis’.

A Japanese-manned submersible discovered a large mass of granite and a large amount of quartz sand 900 miles off the coast of Rio de Janeiro, according to the announcement made by The Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and the Geology Service of Brazil (CPRM).

These materials, normally found on dry land, suggest that a continent once existed in the region and then sank. “It is unusual because it is granite rock,” CPRM geology director Roberto Ventura Santos as quoted by ‘The Telegraph’. “And you don’t find granite on the seabed. It is more usual to find it on the mainland.”

The granite was discovered in a seabed that was estimated to have disappeared under the ocean waters tens of millions of years ago.

“South America and Africa used to be a huge, unified continent. The area in question may have been left in water as the continent was separated in line with the movements of plates,” said Shinichi Kawakami, a professor at Gifu University, Japan Times reports.

The material was reportedly found more than 8,000 feet beneath the sea in a region known as the Rio Grande Elevation.

“This is the region that has been least explored worldwide,” added Kawakami. “So, we believe it is very important to research it.”

“From an analysis, we began to see that the area could be a piece of the continent that disappeared into the sea millions of years ago,” Santos said as quoted by AFP. “This could be Brazil’s Atlantis. We are almost certain, but we need to strengthen this hypothesis.”

The fabled island was first mentioned by Greek philosopher Plato in his dialogues ‘Timaeus’ and ‘Critias’, written about 360 BC. According to Plato, Atlantis was situated in front of the Pillars of Hercules, the phrase that was applied in Antiquity to the promontories that flank the entrance to the Strait of Gibraltar. The civilization of Atlantis conquered many parts of Western Europe and Africa approximately 9600 BC. But the continent is believed to have sunk during a catastrophic natural disaster.

Scientists plan to drill for more samples later this year, as further confirmation is needed. Experts still remain cautious about jumping to conclusions.

The four-thousand-year-old computer

In 1901, a group of divers excavating an ancient Roman shipwreck near the island of Antikythera, off the southern coast of Greece, found a mysterious object - a lump of calcified stone that contained within it several gearwheels welded together after years under the sea. The 2,000-year-old object, no bigger than a modern laptop, is now regarded as the world's oldest computer, devised to predict solar eclipses and, according to recent findings, calculate the timing of the ancient Olympics. Following the efforts of an international team of scientists, the mysteries of the Antikythera Mechanism are uncovered, revealing surprising and awe-inspiring details of the object that continues to mystify.

Brazil to replace oil rigs with ‘underwater cities’

Traditional oil rigs will be replaced with “underwater cities” within a decade under ambitious plans being drawn up by Petrobras, Brazil’s state-owned energy group.

A Petrobras oil platform at Guabanara bay in Rio de Janeiro.

Petrobras plans to turn science fiction into reality to extract oil from the vast pre-salt oil fields discovered off the south east coast of Brazil.
The plan is to construct ‘cities’ more than 2,000 metres under water, containing machines, giant pieces of equipment and robots that could inspect the systems being used to extract millions of barrels of oil. Many operations would be fully automated while others would be controlled by humans at a distance.
Petrobras already owns virtual reality laboratories where engineers can inspect 3D images of oil fields. But now they want to take a further technological leap by installing floating rig equipment on the sea bed.
The machinery under the sea would be capable of separating oil, gas, water and sand, compressing substances and generating enough energy to keep the operation functioning.

April

    There was a nice little girl which name was April. 

    One day, she asked her parents why she was called April. They answered that it was because she was born in April. The little girl liked her name and the month April too. Her parents made her a party, all her friends celebrated with her, and she received a lot of presents.

    One day her mother became pregnant and April had a little brother. Her brother was born in February and everybody came and suggested names for the new baby.

    April didn’t understand what the problem was. If the baby was born in February, the correct name should be February.
