Time travel without time paradoxes

21.12.2023

Scientists say it is theoretically possible to go back in time and make changes without causing undesirable consequences for the future.

Despite the temptation to change the past, scientific research suggests that time travel can be safe and free of time paradoxes. However, this security comes with the inevitability of events changing in accordance with the laws of time, which emphasizes the complexity and mystery of this potential phenomenon.

No one has yet accomplished time travel, especially to the past, in order to change their own future path. Nevertheless, experts continue to develop theories that suggest the possibility of such travel without creating time paradoxes. This means that, in theory, it is possible to go back in time and make changes without breaking the laws of time. At least that's what the theory goes.

The authors of a new study presented their theory explaining how to theoretically travel through time, avoiding time paradoxes. According to classical dynamics, knowing the state of a system at a certain point in time, one can obtain information about its entire history. While Einstein's theory of relativity allows for the existence of time loops, where some events can occur simultaneously in the past and future, existing independently.

The study, based on mathematical calculations, shows that space-time can adapt to changes to avoid time paradoxes. Scientists believe that events will change their course to prevent the emergence of time paradoxes.

Let's take an example: a man goes back in time to prevent the spread of a deadly disease on Earth. If he succeeds, then, according to calculations, the disease will appear in a different way, and thus the time paradox is avoided. Thus, any attempts to change the past may lead to inevitable events.

Experts analyze the influence of deterministic processes on various parts of the space-time continuum and demonstrate that closed time curves (predicted by Einstein's theory of relativity) can correspond to both physical laws and the rules of free will.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

Smart watch Timex Ironman R300 GPS 27.02.2020

The American brand Timex introduced the Ironman R300 GPS smart watch, which offers essential training, heart rate monitoring, tips from top athletes and coaches, a range of daily activity metrics, call and message notifications, the ability to dive in water up to 30 m and good autonomy. At the same time, the cost of the Ironman R300 is only $120.

Like the Timex Ironman One GPS, it's more of a fitness band than a smartwatch, but the company is positioning it as a "smartwatch for sports." Potential Ironman R300 owners are users who want a reliable fitness tracker without unnecessary features, but with a long battery life. The manufacturer claims that the autonomy of the gadget is up to 25 days with GPS turned off. If it is enabled, the operating time is reduced to 20 hours.

The rest of the features are what you would expect from a device like this. Here you can change the watch face, scroll through the screens and view training data. The watch comes with a silicone strap in grey, black and silver color options.
