Change Earth’s rotation

October 2, 2025 by usatoday24

The dams are colossal engineering works that provide numerous benefits to the surrounding cities, such as energy and flood protection. However, They are often accompanied by national and international controversies. And no dam has acquired both renown (and controversial) and the Chinese dam of The three throatsone of the most titanic construction projects on the planet and the largest hydroelectric dam. Its connected reservoir is capable of containing a volume of water so large that the rotation of the Earth has changed, extending the duration of the day by 0.06 microseconds. The three throats. Built along the Yangtze River in the province of Hubei, it was planned in 1919 by the first president of the Republic of China, Sun Yat-sen, as a measure to control the floods of the river and generate energy. But, above all, to become a symbol of China’s power. Although its construction would not begin until December 1994 and would be put into operation in 2009. It has more than 2 kilometers long and 182 meters high. When it is at its maximum point, can contain 42,000 million tons of water. Suffice it to say that 510,000 tons of steel were needed to build it, which would be needed to erect 60 Eiffel towers. What is it for? It has three objectives: flood control, hydroelectric energy production and improve navigation. Keep in mind that the three throats generates today 11 times more energy than the gigantic hoover preythe world’s largest power plant with 22,500 MW. And through 34 huge generators, supports a large part of the Chinese nation. Besides, Helps keep the Yangze River at baythe longest third in the world, during the flood season protecting adjacent cities such as Wuhan, Nanjing and Shanghai. It has slowed the rotation of the Earth. However, there is a price to pay to store so much water. Once the dam reservoir, the weight of the dough, which is more than 39 billion kilos, It is enough to slightly change the rotation of the earth. As? The inertia of the earth depends on its mass (water) and the distribution of that mass with respect to the axis of rotation. The axis of the Earth It is an imaginary pole that crosses the center of the earth from “up” to “down.” The earth revolves around this pole and performs a complete rotation every day. But as the dough is redistributed on the planet, This change slightly alters rotation. And the greater the distance of a mass (relocation of the water from other areas to the Chinese reservoir) to its axis of rotation, the slower it will turn, therefore It affects the duration of earth days. To understand the phenomenon, it is only necessary to visualize the turn movement of an ice skater: if its mass is uniformly distributed (for example, collecting their arms towards the body), it will turn better and faster after a few laps. If the dough changes, rotation and turn also change. The result. That means that raising 39 billion kilograms of water at 175 meters above sea level increases the inertia of the earth and, therefore, slows its rotation. However, according to NASA, the impact is minimal. His scientists calculated That the change of such mass increases the duration of the day by just 0.06 microseconds and makes the earth just a little more round in the center and flatter in the upper part. It has passed other times. In fact, hundreds of phenomena that alter that movement are produced every year. He tsunami that hit the Southeast Asia in 2004 or the 2010 Chilean earthquake They also affected the rotation of the planet. NASA then confirmed that the 2004 Indonesian earthquake had decreased the duration of the day by 2.68 microseconds. What affects us? Nothing. Although it sounds very shocking, the reality is that we will not notice any change. Miguel Sevilla, deputy director of the Institute of Astronomy and Geodesia, He defended years ago in this information article That these phenomena “have no greater significance, apart from the large material and human damage they cause.” Although they serve to warn us of “the effects they have on people, buildings and in nature.” Other controversies that do matter. In fact, beyond how this Chinese dam affects the rotation of the earth, the project has been plagued with other controversies that do significantly affect the life of humans and ecosystems. One of them is the amount of damage that causes the environment. It is estimated that 70% of China’s fresh water is contaminated and The dam could be worsening the situationsince it is based on old waste and mining operations facilities. Every year 265 million gallons of wastewater are deposited without treating on the Yangtze River. On the other hand, when the project was built, 1.2 million people were forced to relocate In new homes. And currently, the Chinese government is still migrating people out of the area.

We have also changed the rotation axis

A few years ago, Jet Propulsion Lab scientists They estimated That the filling of the three throats, the huge hydroelectric project of China, implied the movement of a mass of water so vast that it was capable of lengthening 0.06 microseconds The land day. The Chinese dam is a singular case for its magnitude, but it is only one of the tens of thousands of reservoirs that populate our planet. The global impact of these reservoirs has now undergone. Displacing the poles. A new study He has found evidence of the geological impacts that the construction of dams can have on a global scale. They observed that the construction of dams had caused a slight displacement of the geographical poles of the planet, Geographical poles? As little ones, they will probably teach us that the geographical poles and magnetic poles of our planet were located at different points of their respective polar circles. They would surely teach us that the magnetic poles tend to move slowly over time while the geographical poles remain static forming the Earth’s rotation axis. This is more or less true, but not at all: geographical poles can also move. The reason is in the structure of the earth. Our planet is not a block of uniform rock but is formed by several concentric layers. While the outer layer is essentially solid, the interiors are not. As if it were a mat on a pool, the “float” earth’s cortex on the mantle, which implies that it can move more or less independent displaced by the physical forces that are applied in each case. Redistributing the dough. Forces that in turn depend in part of the distribution of the masses that we find in this superficial part of the planet, a distribution that is altered every time we introduce changes in the geography of our planet. These changes include the displacement of large masses of water to the swamps, water that in “normal” conditions would have returned to the ocean dragged by the rivers in which we build prey. “As we catch water behind the dams, we not only eliminate the water from the oceans, reducing sea level, the mass is also distributed in a different way around the world,” explained in a press release Natasha Valencic, co -author of the study. 6,862 reservoirs. The study responsible for the study analyzed the impact of water accumulation in 6,862 reservoirs, an accumulation of water that twice represents the volume of the Grand Canyon of Colorado. The team observed that between 1835 and 2011 this accumulation of water could be responsible for almost a meter of displacement in the axis of terrestrial rotation with respect to the planet’s surface. The displacement would be divided into two stages, the first between 1835 and 1954, in which the pole would have displaced 20.5 cm to the 103 meridian as a result of the construction of dams in Europe and North America. The second, between 1954 and 2011, would have been dominated by the construction in Asia and Africa del Este, carrying the 57 centimeters pole towards the 117 western meridian. The details of the study were published In an article In the magazine Geophysical Research Letters. More than reservoirs. The implications of these geographical changes are not extreme: after all the tectonic plates do not stop moving at our feet despite the fact that their rhythms usually be more slow. However, knowing these little movements can help us understand some of the geological dynamics and the impact of the human being on them. “We are not going to fall into a new ice age because the pole has modified around a meter in total, but it has implications for sea level,” Clarified Valancic.

24.1% of stress rotation and burnout

June 10, 2025 by usatoday24

Detachment and job dissatisfaction have grown in a technological field shaken by changes of different kinds: template reductionschanges in working hours and changes in Labor policies. That has resulted in an increase in labor rotation in 2025. Stress and The lack of motivation They put the icing on a situation in which more and more employees look for a new job, according to survey data ‘Employee Experience Report 2025‘ of Nailted. Not just losing an employee. The last Employee Experience Report de Nailted, which includes the opinion of more than 32,000 employees in 126 companies. Such and As they point out From Manfred, this data reveals that the increase in template rotation is the direct consequence of a decline labor commitment and an increasingly deteriorated employee experience. “We are in a moment of emotional wear on the teams, and we must act with head (and with data),” warn the authors of the report. “When someone leaves, not only changes a name in a database: knowledge, relationships and part of the culture of the team are lost.” Employees do not find their place. In 2025, labor rotation They have reached 24.1% compared to the 19.19% registered in 2024. The authors point out this data as an alarming figure that reflects emotional wear in equipment that not only affects the stability of companies, but also puts at risk the continuity and quality of technological projects. Of this total, 8.73% of the outputs correspond to voluntary outputsslightly less than 9.39% of the previous year, motivated mainly by dissatisfaction and discomfort in the job. On the other hand, layoffs encouraged by companies have increased considerably, reaching 8.87% compared to 6.98% of 2024. These variations reflect a context of template settings On the part of the companies, and a scenario of uncertainty for cooling the labor market, which makes employees looking for a new job, think twice before changing. ENPS: A thermometer that alerts the commitment. One of the values that the Nailted study calculates is the ENPS index (Employee Net Promoter Score), which measures employees’ emotional commitment to their companies on a scale of -100 to 100, being 0 a neutral assessment. The data suggests that this index has suffered a significant fall in 2025, standing at +17, which represents a drop of 9 points compared to the previous year and the worst data of the historical series. To put it in perspective, in 2021 the index reached +32 and in 2023, after a massive wave of layoffs in the technological sector, it remained in +36. This sustained descent reflects a clear loss in the satisfaction and emotional bond of workers with their companies. As the report points out, “less people would recommend your company as a good place to work”, a symptom confirming the Increase in labor rotation. Stress as a trigger. The increase in rotation is closely linked to the increase in work stress. In 2025, 18.12% of employees declare work Under high stress, while 29.7% experience it occasionally. This constant pressure contributes to emotional wear that directly impacts the motivation and job satisfaction. Consequently, aspects such as feeling satisfied with the work, speaking positively about the company or feeling proud of the work carried out have decreased in different percentages compared to previous years. Reading is aggravated when only 58.89% of workers feel that their company supports them to Manage stresswhich represents a decrease of 5.98% compared to 2024, evidencing an increase in the feeling of abandonment of companies in terms of well -being. This is not paid. To the fall in the perception of the welfare of the workers, the salary injustice is added. Barely 43.21% consider that Your remuneration is fair In relation to their experience and responsibilities, a figure that has dropped 4.22% in one year. This negative perception It is one of the main causes that feed the rotation, since it directly affects the motivation and commitment of employees, deriving in the Burned worker syndrome either Burnoutas well as in an increase in “Silent resignation“That is, just do what is strictly necessary not to be fired.

Generating electricity using earth rotation seemed impossible. These physicists have shown that it is not

March 21, 2025 by usatoday24

In July 2016, two American physicists, Christopher F. Chyba, from Princeton University, and Kevin P. Hand, from the NASA jet propulsion laboratory, published in Physical Review Apply A very exotic scientific article. In his text they defended the possibility of generating electricity taking advantage of The Earth Rotation Movement. His proposal required to build a device that was able to interact with The magnetic field of our planetbut at that time very few scientists took it seriously. Despite the bad initial reception that his job received, Chyba and Hand have spent the last nine years trying to build his electricity generation machine with the purpose of demonstrating that, indeed, his proposal works. However, during this period they have joined a third physique, Thomas H. Chyba, who investigates in Spectral Sensor Solutions, an Albuquerque company (New Mexico). It is dedicated, among other things, to develop electrooptic sensors to detect chemical, nuclear, biological and radiological threats. Chyba and Hand were right from the beginning On March 19, these three physicists published in Physical Review Research A new scientific article in which they experimentally demonstrate that, as suggested in their 2016 text, it is possible to generate electricity taking advantage of The rotation movement From Earth. To carry out their demonstration they have built the apparatus capable of interacting with The Earth’s magnetic field of which they talked in their 2016 article. Interestingly, this device is very broadly speaking a manganese and zinc ferrite cylinder that behaves like a magnetic shield. The experiment of these three physicists has shown that 18 electricity microvolts were being generated through the cylinder Once they had it ready, they guided him in a north-south direction with an angle of 57 degrees with the purpose of being perpendicular to both to the Earth Rotation Movement as to its magnetic field. And then they placed electrodes at each end of the cylinder to be able to measure the voltage of the electric current that they expected to be generated. And they succeeded. His experiment showed that they were being generated 18 electricity microvolts through the cylinder without any other energy source. According to these physicists, the only plausible possibility is that, as they expected, the land rotation movement is responsible for the generation of this small amount of electricity. When Chyba and Hand proposed their idea in 2016, other scientists criticized it by arguing that any voltage caused by a device similar to that they have finally built would be canceled at the time when electrons were repositioned during the generation of an electric field. But your experiment shows that it is possible to capture that voltage. An 18 microvolt voltage is insignificant in practice. It’s true. However, this is not important; The relevant thing is that, apparently, the proposal of these three physicists works. In fact, your plan goes through climb this technology To generate much more electricity, enough at least to be useful. In any case, there is something important that we should not overlook: its experiment still has to be replicated by other scientists and in other test scenarios to verify that this voltage has not really been generated by any other external source that, perhaps, the protagonists of this article have not taken into account.
