'Sunken World' discovered at the bottom of the Pacific Ocean!
Scientists
have discovered a possible part of the Earth's ancient crust, or the
so-called 'sunken Earth', at the bottom of the Pacific Ocean. The
astonishing discovery was made possible through state-of-the-art
geophysical mapping technology and seismic wave analysis methods.
A new study published in the journal Scientific Reports suggests that the remains of tectonic plates are hidden not only in submerged areas but also in the interior of continents. However, these remains are located in areas where no tectonic collisions have occurred in the past. Such anomalies have been detected in particular under the western Pacific Ocean.
How these remnants got there is still a mystery, according to the research team.
In this study, researchers used seismic waves to create a clear map of the Earth's interior. The new method, called full-waveform inversion, combines data from seismographs from individual earthquakes to create a clear picture.
In addition, the study used the Piz Daint supercomputer in Switzerland. As a result of this method, scientists have found that there are parts of submerged tectonic plates on the ocean floor and in the continental interior.
The researchers believe that these parts may be ancient materials left over from the early formation of the Earth's crust, which formed about four billion years ago. Or they may be dense materials that have formed inside the Earth over the past few hundred million years.
But they are not yet confirmed. "We don't know exactly what they are, but we are examining the properties of different materials," said Thomas Schouten, the study's lead researcher.
The researchers also said that the speed of seismic waves suggests that these parts are similar to submerged tectonic plates. However, more research is needed to confirm whether they are really the same type.
"We want to gather more information about the properties of different materials through wave motion," said Schouten. "This will help us understand the true nature of these structures."
This discovery opens the door to new research into the Earth's interior. In the future, this research will help us understand more clearly the unknown chapters of geological history."
Was the Moon created by the Earth? New study reveals surprising information!
A new study on the origin of the Moon and the source of Earth's water has revealed surprising information. Scientists from the University of Göttingen and the Max Planck Institute for Solar System Research (MPS) in Germany conducted the study. Their study found evidence that the Moon was originally formed from material from the Earth's crust.
The study, published in the Proceedings of the National Academy of Sciences, analyzed oxygen isotopes from 14 lunar samples and 191 Earth samples. According to data obtained by the laser fluorination method, the oxygen-17 isotopes of the moon and Earth are very similar.
The study challenges the widely held Theia theory of the moon's origin. It was previously thought that a protoplanet called Theia formed the moon when it collided with Earth. But new research suggests that Theia's crust was probably destroyed first. The collision took the form of a "metal bullet" that formed the moon from material ejected from Earth's crust.
The findings also spark a new debate about the origin of Earth's water. It was long believed that the Late Veneer Event theory, which holds that water came to Earth after the Moon formed, was caused by a comet or asteroid impact. But study co-author Mike Fisher said the isotopic similarities between the Moon and Earth rule out many types of meteorites as the source of water.
The study suggests that a type of meteorite known as enstatite chondrites, which have isotopes similar to those of Earth and carry significant amounts of water, may be the original source of Earth's water.
The findings are re-evaluating conventional wisdom about the history of the Moon and Earth. They could help us better understand the deep connections between the Moon and Earth and the complexity of planetary evolution.
