Jupiter deprived the solar system of the planet

08.08.2018

A team of astrophysicists from the University of Toronto (USA) found that a close collision with the planet Jupiter, which could have occurred approximately 4 billion years ago, may have led to the expulsion of another giant planet from our solar system.

For years, scientists have debated the existence of a fifth giant planet, following Jupiter, Saturn, Uranus, and Neptune, which may have been pushed out by Saturn or Jupiter in a planetary collision.

As a result of this collision, an unknown planet could lose its gravity and binding to a star and fly out of our solar system. The new data obtained indicate that, after all, Jupiter became the culprit for the departure of the planet from our system.

To come to this conclusion, astrophysicists studied the moons of the two gaseous giants mentioned above, as well as their moons. For this, computer simulations were used based on the current trajectories of Callisto and Iapetus, satellites in normal orbit around Jupiter and Saturn, respectively.

Once the simulations were done, the scientists proceeded to measure the probabilities that Callisto and Iapetus would produce their current orbit, if their parent planets removed the hypothetical fifth planet from the solar system, this event would significantly change the moon's original orbit.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

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, ... >>

A new data rate record in a coherent optical network 03.10.2022

Nokia Bell Labs has demonstrated the ability to transmit optical signals over 100 km over standard single-mode fiber (SSMF) at a record high speed of 260 Gbaud (2,08 Tbps).

During a demonstration at the European Optical Communications Conference (ECOC) 2022 in Basel, Switzerland, a provisional speed record of 220 Gbaud was broken.

This result marks the first milestone for scaling long distance data transmission systems at rates greater than 2 Tbps per wavelength. The issue of improving the energy efficiency of transponders is a constant challenge for the industry,” said Haik Mardoyan, senior researcher at Nokia Bell Labs.

The specialist collaborated with Keysight Technologies to develop dual polarization quadrature phase shift keying (DP-QPSK) coherent transmission technology over 100 km single-mode fiber. Keysight's new M8199B Arbitrary Waveform Generator (AWG) provides 75 GHz bandwidth and uses a 110 GHz lithium niobate thin-film I/Q modulator.

This allows the research and development of transmission systems operating at symbol rates up to 260 Gbaud, allowing to achieve net data rates of more than 2 Tbps in a coherent optical communication network.

The growing spread of artificial intelligence requires the emergence of new levels of server and network performance that must scale computing resources within reasonable energy usage limits. Higher data rates and new modulation formats will be among the leading technologies for the industry.
