The authors of a new study published in the journal Classical and Quantum Gravity provide a theoretical basis for warp drives, suggesting that the technology for extremely fast space travel may not remain forever inaccessible to humanity, reports Space. Science fiction fans are probably familiar with warp drives. These hypothetical engines control the fabric of spacetime, compressing it in front of the spacecraft and expanding it behind. This creates a kind of warp bubble that allows the spacecraft to travel either at the speed of light or even faster. 30 years ago, physicist Miguel Alcubierre published a groundbreaking paper in which he described how a true warp drive could work. But this propulsion system required negative energy, that is, an exotic substance that may or may not exist. It also suggested the use of dark energy, that is, a mysterious force that apparently causes the accelerated expansion of the Universe. The authors of the new study suggest that a true warp drive does not need exotic negative energy at all. According to scientists, this research changes the understanding of warp drives, because they were able to create the first of its kind model of such a device, and it proves that warp drives are not completely relegated to science fiction. According to the scientists, their model “uses a complex mixture of traditional and new gravitational techniques to create a warp bubble that can move objects at high speeds without exceeding the limits of known physics.” Although the explanations of the new model are very complex for ordinary science lovers. For example, the scientists write in the study that “the solution involves combining a stable shell of matter with a displacement vector distribution that closely matches well-known warp drive solutions such as the Alcubierre metric.” This is the name of the warp drive proposed by Alcubierre. According to scientists, warp engines are exotic solutions to Einstein’s theory of relativity that offer a faster way to travel through space. The authors write that their “research shows that classical warp drive spacetime can be brought to satisfy energy conditions by adding a shell of ordinary matter with positive mass consistent with relativity.” Scientists have shown in their model that their warp drive cannot reach speeds exceeding the speed of light, although it can approach this speed (300 thousand km/s). Even if other scientists confirm that the mathematics presented in the new study is correct, humans are still a long way from being able to create a true warp drive. The study’s authors acknowledge this and believe that their results could be the first step towards fast interstellar flights. Scientists believe that in the future it will be possible to create a real warp drive that would not violate the rules of classical physics, but would allow movement at sub-light speeds through space.

Although the Standard Model of particle physics does a great job of explaining the universe, there are still many mysteries that need to be solved. Physicists believe that there are many more elementary particles that are hidden from us. With the help of a new CERN project called “Search for Hidden Particles,” physicists plan to discover the hidden elements of the Universe using a beam of protons, a metal block and extremely sensitive sensors, reports Popular Mechanics. When 12 years ago, scientists from CERN discovered the Higgs boson, which had previously been considered a theoretical particle, the Standard Model of particle physics seemed to be complete. But then it turned out that this was not so. Physicists have observed phenomena that do not fit into the Standard Model. This applies to dark matter, neutrinos and antimatter. Physicists still cannot detect dark matter particles or itself directly. It is also not clear why neutrinos have mass. It is also unclear why there is less antimatter in the Universe than ordinary matter. To answer these questions, we need to delve deeper into the world of particle physics, and that’s where the Search for Hidden Particles project comes in, with the goal of finding the hidden secrets of particle physics. CERN has officially given the go-ahead to this project. The project should begin in 2027, and the first results should be obtained in 2030. Physicists will look for weakly interacting particles such as dark photons, axions, heavy neutral leptons and many others that are hidden from scientists but hypothetically should exist. The discovery of these particles is of great importance, because the Standard Model of particle physics can only describe 5% of the matter in the Universe. That is, 95% of the Universe is hidden from us. During the experiment, physicists will fire beams of protons at almost the speed of light, collide them, and then study the results. Proton beams will be launched at the Proton Super Synchrotron particle accelerator. Once the beam of protons reaches a fixed target, that is, the so-called large metal block, the resulting collision will produce a variety of particles, including charming mesons and also photons. While existing CERN experiments focus on the energy frontier, where relatively heavy particles collide and break up into possibly unknown particles, this project explores the “intensity frontier,” which uses precise measurements to analyze quantum effects. Scientists believe that with the help of this project it will be possible to discover the missing physics.

Researchers say that our civilization is at a level of development that does not allow contact with alien life. In searches for alien civilizations, people tend to look for the types of signals that they themselves could broadcast, assuming that aliens would use the same technologies, writes IFLScience. This conclusion is quite logical, but far from ideal. As the example of humanity itself shows, intelligent civilizations can quickly abandon old discoverable technologies, replacing them with new ones. For example, people quickly moved from using analog signals to digital signals for communication. At the same time, analog signals were better detectable, but alien civilizations could also abandon them, moving to more advanced technologies. Scientists have spent a lot of time searching for the type of signal that a more advanced civilization would be able to send, as well as what to say in that message. “In the 1960s, the idea was put forward to use for messages the well-known frequency at which neutral hydrogen is emitted into interstellar space at a frequency of 1.42 GHz. Because such natural radiation is distributed throughout the galaxy, the idea is that any intelligent civilization would know about it and could target that frequency to transmit its own signals,” says astronomer Brian Brzycki of Berkeley. Sending signals to every corner of the galaxy or even the universe, especially continuous signals that increase the chances of detection, requires a lot of energy, much more than we can generate. In 1963, astronomer Nikolai Kardashev tried to calculate what energy could be used to send these kinds of signals. He also suggested the level of development of a civilization that would be capable of sending such signals. Thus, hypothetical civilizations were divided into 3 types depending on the energy that they are able to obtain from the environment. Type I civilizations can use all the energy available to them on their planet (about 4×1019 ergs per second), using it for their own purposes. Type II civilizations can harness the energy of their star, for example using a Dyson sphere. It is a megastructure built around a star to generate energy. Type III civilizations can harness the energy of their entire galaxy. The energy production of type II and III civilizations is very large indeed. It is estimated that, based on an increase in energy production on Earth by 1% per year, humanity will reach the above-mentioned stages only after 3200 years, and then after 5800 years. New theories also suggest the existence of a Type IV civilization, which is capable of harnessing the energy of the entire observable universe. At the same time, according to scientists, if you look at the current energy consumption of humanity, people are a civilization of type 0.72. According to experts, the chances of discovering a Type I civilization are extremely low, despite the fact that this type of civilization is far beyond our current capabilities. But signals from Type II and III civilizations can be detected by less advanced civilizations using instruments similar to our own radio telescopes. True, civilizations like ours are unlikely to be able to respond to the received signal.

Celle di Bulgheria, a quaint town known for its rich history and natural beauty, found itself at the center of an aerial mystery this May. The photograph, captured by local resident Anna Ida Guida, shows metallic, saucer-shaped object hovering in the clear skies. Taken from her balcony, the image was one of two snapped in quick succession; the first showed an empty sky, while the second revealed the unexpected guest. “I took a picture outside my balcony, actually two, at the same time, in one there is nothing and the other is this posted, can anyone tell me what it is?” Anna wrote. “Me, while I didn’t see anything, I wasn’t looking at my phone but at the sky, because it was a picture made enough to show time to my boyfriend.” Guida’s post on Facebook, seeking explanations for the curious object, sparked a wave of theories. Suggestions ranged from the mundane—a stray black plastic bag caught in the wind—to the extraordinary, with some proposing the possibility of an extraterrestrial craft. The intrigue deepened as the image was relayed to the Mediterranean Ufological Center, an organization dedicated to the study of unidentified flying objects. The center’s experts are now meticulously analyzing the photograph for any clues that could shed light on the object’s origin and nature.
