Giant hole appeared in a city in Chile: the authorities are puzzled

Chile’s government announced Tuesday that it is investigating the causes of a sinkhole 32 meters in diameter and 64 meters deep appeared near a copper mine in the Atacama desert.

Experts traveled to the municipality of Tierra Amarilla, some 800 km north of Santiago, where the huge hole appeared over the weekend, reported the National Mining Subdirectorate of the National Geology and Mining Service (Sernageomin) in a statement.

A security perimeter of 100 meters was established around the sinking, located within the grounds of the Alcaparrosa de Candelaria mine, operated by Canada’s Lundin Mining.

According to a company statement, “there was no impact on personnel, equipment or infrastructure” and the sinkhole has remained stable since its detection.

As a preventive measure, “development work was temporarily suspended in an area of ​​the Alcaparrosa underground mine”, indicated the company, adding that no movement has been detected.

Specialists and mining personnel seek to “clarify the causes and ensure that all security measures are taken to safeguard the lives of workers and communities near the site”, pointed out David Montenegro, director of Sernageomin.

He added that professionals toured the area “to see if there are cracks and they entered the mine to see its real state.”

The huge hole caused surprise in the nearly 13,000 inhabitants of Tierra Amarilla.

Cristian Zúñiga, mayor of Tierra Amarilla, explained to local media that the population always there has been fear of incidents due to mining operations in the area.

This huge sinkhole is something that has not been seen in our community. We request that it be possible to clarify why this event occurred, if the collapse is the product of mining activity or if it is of another nature, “he said.

Chile is the world’s leading producer of copper, responsible for more than 25% of the global supply.

Black hole: reveal what would happen if you fell into one of them

Today black holes have stolen the limelight and are the center of various conversations around the world, after this Thursday, May 12, the first image of a black hole in the center of our galaxy was known.

This was confirmed, through a global press conference, by the international team of astronomers who have worked on a project known as EHT (Event Horizon Telescope).

During the event, scientists shared the “silhouette” image of the black hole, which is called Saggitarius A*, on a luminous disk of matter. It is an image similar to that of the gigantic hole in the distant galaxy M87, larger than ours, and that the EHT released in 2019.

Definitely, It is a great advance for science, which has tried for decades to unravel the mysteries that black holes hold. And it is that, technically, black holes cannot be examined, due to their density and their gravitational force, from which not even light can escape, what is actually detected is the matter that circulates around them.

What would happen if a human fell into a black hole?

After knowing the most recent image of a black hole, people’s concerns are once again on the table. While some wonder what black holes really are, where they come from and what damage they could cause if they are close to Earth, others wonder what would happen if a human being fell into one of them.

The first thing, it should be said, is that according to National Geographic in Spanish, the black hole identified in the Milky Way is located about 27,000 light years from Earth, right in the center of our galaxy. “It is extremely heavy: its mass is equivalent to that of four million suns,” he says.

Precisely because of these characteristics, Saggitarius A is classified as a supermassive black hole. Among other types of black holes, notes the journal In exclusive, In an article published in its science and health section, there are the stellar ones, which originate from the collapse of stars and whose mass is greater than three suns; the intermediate ones, which have masses between 100 to a few million suns, and the microscopic or miniature ones, which in theory are those with masses less than the Sun.

“Supermassive black holes at the center of galaxies are thought to have been created by subjecting these centers to extreme conditions during galaxy formation. These black holes are known to keep growing, by gobbling up nearby objects or merging with other black holes.

The curiosity to know what would happen if an object, or even a human being, fell into one of them, is not new. This is a question that several experts have answered forcefully: there would be no chance of survival.

“The force of gravity would stretch us until we became a thread and the temperature would be such that it would vaporize us,” they point out from the magazine.

An opinion that was already shared by Andrea Ghez, winner of the 202nd Nobel Prize in Physics, in an interview with AFP. In this, she assured that it would not be possible for the human being to survive. “If we fell feet first into a black hole, the first thing that would happen is that the gravitational force would be much stronger on the feet than on the head, which would rip us apart. So we wouldn’t feel anything because we wouldn’t exist anymore, we wouldn’t survive,” she explained.
