A Space Barrier Around Earth

A human-made space barrier around Earth was first observed by NASA in 2012. This zone of space weather has been caused by radio waves that we’ve been blasting into the atmosphere for decades. Experts say it helps protect humankind from dangerous space radiation.

NASA sends probes to different parts of our solar system, including the Van Allen Belts. This donut shaped area of radiation follows the equator, leaving the Poles free. The Van Allen Belts react to the magnetosphere created by the bombardment of radiation.

When spaceflights pass through areas of the Van Allen Belts, they must include radiation shielding to protect the crew and equipment.

Now we have a new protective barrier. Probes launched in 2012 detected it, and 2017 probes gave us evidence of a radio-wave barrier emanating from Earth. It seems very low frequency (VLF) radio communications are far more common now than in the 1960s and they can influence how and where certain particles move in space.

It turns out that very low frequency waves can cancel out or repel the radiative advances of the Van Allen Belts. The military usually use very low frequencies, which were the first frequencies used for broadcasting. Since then, private and recreational users have been pushed up the spectrum. AM waves are pretty low, but FM is farther up. Different wavelengths are used for different purposes.

VLF waves blanket the Earth without interfering with other radio signals or other kinds of waves flowing around the Earth. But VLF waves travel far enough into space to push away harmful radiation.

This could mean that space flights could use VLF technology to punch holes to travel through radiation fields.

7,000-Year-Old Sunken City

They may not have found Atlantis yet, but another sunken city has been found. Like Atlantis, this city also inspired a myth. An island that was partly submerged off the coast of the Ile de Sein of France gave the Brittany region its own local lore for thousands of years.

It was here that marine archaeologists spotted the remains of a 7,000-year-old wall about 30 feet below the surface. It belonged to a stone age civilization and is thought to have been one of two things; either a fence to collect fish or a dike built to protect against rising waves.

LIDAR data found eleven structures at the bottom of the ocean. Sea level data reflecting changes in the sea level and vertical land movement indicate they dated back to between 5,800 and 5,300 BCE. This was a time of transition from the hunter-gatherer lifestyle to permanent settlements. At that time, the shoreline was several miles out to sea.

This find predates the first Neolithic megaliths in Brittany by at least 500 years. But little archaeological work has been done in the deep areas of the Brittany coast because of difficulties in accessing such sites.

Shell middens near the short and megaliths further out give evidence of coastal human populations in the region, but the ocean has not given up many artifacts. Fragments of this wall weigh 3,300 metric tons, which might support the idea that it was built to prevent flooding when the sea level rose.

Whatever the purpose of this wall, it was designed to withstand storms and erosion. Standing stones within the structure are similar to others found in inland Brittany and parts of Stonehenge, the largest being nearly 10 feet high. This structure’s arrangement of monoliths, slabs, blocks, and boulders suggests a complex architecture, which has not been found in nearby fish fences. The community that built the megalith must have had technical skill and social organization.

There may also be a link to the City of Ys, which involves a Breton legend passed down through centuries by oral tradition. Ys is thought to have been submerged in the Bay of Douarnenez, which is just east of Ile de Sein. So this legendary city might have actually existed in prehistory.
