The earth is pushing the moon faster

29.05.2013

Scientist Matthew Huber of Purdue University found that the Earth is pushing the Moon away from it faster than at any time in the last 50 million years. Due to the ebbs and flows, the satellite of our planet is moving further and further away from the Earth, which also affects the planet itself.

The moon's gravity creates a daily cycle of tides. This process slows down the rotation of the planet around its axis and causes the Moon to move away from the Earth by about 3,8 cm per year. It is logical to assume that if the rate of removal of the Moon has always been the same, then the age of the satellite can be calculated from the removal of the orbit of the Moon - it turns out about 1,5 billion years. However, this is clearly an incorrect figure, since some lunar rocks are much older - 4,5 billion years, which is comparable to the age of the Earth.

Matthew Huber and his colleagues studied the ocean floor and the contours of the continents that existed 50 million years ago. As a result, it was possible to create an accurate model of the ancient tides, and hence to calculate the gravitational interaction of the Moon and the Earth. It turned out that in ancient times the energy of this interaction was only half of the current one.

It turns out that the Moon is moving away from the Earth at an increasing speed, and so far the reason for this phenomenon is not fully understood. Perhaps the reason is that the North Atlantic Ocean is now much wider than it was 50 million years ago. Because of this, very large waves and high tides are formed, which push the moon harder.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

Right ear hears better 09.12.2017

When the brain is busy, cognitively loaded, a person relies more on the right ear to process and store sound information, and this phenomenon, developing in children, persists in adults.

Scientists from Auburn University (USA) recruited 41 volunteers aged 19 to 28 years to participate in tests related to the dichotic listening technique.

Dichotic listening is often used to help diagnose auditory processing disorders, as well as to understand disorders that cause auditory hallucinations, such as schizophrenia. Such tests involve feeding two different streams of audio information through headphones. This is, most often, speech, a voice reading out sentences or sequences of numbers; the subject should try to focus on one of the streams (separation) or both (integration), repeating the words he heard.

With each subsequent test, the number of items in the list, which was voiced and fed into the headphones, increased by one.

The researchers found that there was no difference between the quality of information stored in the right and left ears - if the number of items in the list did not exceed the amount of memory of a person. However, when the number increased, exceeding this limit, the subjects memorized better in the right ear. On average, this improvement was eight percent, but in some subjects it reached forty.
