"In quantum theory, strict rules of information conservation apply. If you know the exact state of a quantum system at this moment, then the Schrödinger equation, the absolute foundation of quantum mechanics, allows you to precisely calculate what happened before and what will happen in the future, i.e., how a particle will behave, for example. From the Schrödinger equation, it follows that information in the universe cannot simply disappear. "

"The mathematical structure would not end in a singularity but would open up to a second, identical side. [...] Structurally, the solution features a region interpreted as a white hole, which is a time-reversed solution of Einstein's field equations with respect to a black hole. A white hole is a black hole running backwards in time. Just as black holes swallow things irretrievably, so also do white holes spit them out. [...] General Relativity is time symmetric. "

"Trained US Navy pilots have reported encounters with mysterious objects now called UAP, such as the phenomenon involved in the 2004 USS Nimitz incident. These objects or phenomena, as it is difficult to determine what they are, ignored basic laws of aerodynamics, accelerating to speeds that would destroy known materials without visible propulsion. "

"In 1977, the great Big Ear radio telescope registered a powerful narrow-band impulse from the depths of space lasting exactly 72 seconds. So regular and strong that the potential for an intelligent message trapped within it earned the name of the Wow signal. "

"However, neither the Wow signal nor radio anomalies have ever been repeated in a way that allows falsification, and aviation reports, although confirmed by governments as unresolved phenomena, do not give us tangible evidence. "

"with the development of technology, we are getting increasingly destructive and increasingly capable of large-scale destruction tools. "

"Photons emitted by the first stars as visible or ultraviolet light, traveling through the expanding universe, were stretched into the infrared range. And therein lies Webb's genius. Our eyes, and even the Hubble telescope, cannot see this infrared. Cosmic dust and the expansion of the universe have hidden these primordial objects from us for centuries. Webb, with its infrared detectors, simply lifts this veil. "

"And it follows that the average density of a supermassive black hole, one with a mass of billions of suns, can be comparable to the density of water, or even air. It's hard to imagine that matter with the density of water would form a hard, impenetrable shell on which everything breaks. "

"However, if we take into account the fact that black holes evaporate and will eventually disappear, even if it takes 10 to the power of 100 years, then their horizon is not eternal, it is temporary, only this time is simply long. "

"For us, external observers, this process never ends. The battery never crosses the horizon, because time slows down, it freezes just above it, slowing down infinitely. "

"In astrophysics, a gravastar (a blend word of "gravitational vacuum star") is an object hypothesized in a 2001 paper by Pawel O. Mazur and Emil Mottola as an alternative to the black hole theory. It has the usual black hole metric outside of the horizon, but de Sitter metric inside. On the horizon there is an ultra-thin, incredibly tight shell of entirely new, unique exotic matter. This solution to the Einstein equations is stable and has no singularities. Instead, a gravastar is filled either with dark energy or with vacuum energy. "

"If we placed a camera on the surface of a collapsing star, for it the process would last a finite and very short moment. Such an observer would cross the horizon and reach the singularity in a finite proper time. "

"In the strict mathematical sense, a black hole in general relativity possesses an eternal event horizon. A horizon that lasts forever, always and forever. "

"If matter were to fall onto the hard surface of a Gravastar, we should see powerful flashes of energy at the moment of impact. Telescopes, however, see nothing of the sort. Matter seems to disappear into the blackness without any impact, yes, and flash. "

"After landing in Utah, technical problems began on Earth. It turned out that we could not open the main container. Two of the 35 fastening screws got stuck for good. "

"The entire operation took place in a special glove box filled with nitrogen to avoid contact of the samples with terrestrial oxygen and moisture. Scientists simply did not want to contaminate the samples. "

"The Ozaj Risrex mission sent evidence to Earth that the components we are made of could have originated billions of kilometers away, even before Earth cooled. "

"When the arm touched Bennu, it encountered no resistance. It plunged into the asteroid to a depth of almost half a meter like soft foam. If the programmed reverse thrusters had not fired, the probe could have been sucked in and trapped inside the asteroid. "

"The key to survival was a thermal shield made of Pika material. This is an acronym for Phenolic Impregnated Carbon Ablator. The operation of such a shield is based on the phenomenon of ablation. "

"NASA chose this target not by chance. Bennu is so old that its material has not undergone significant geological changes, such as those that occur on planets. It is a primordial soup of matter frozen in time, from which Earth also originated. "

"This substance forms layers on ice grains and minerals within the sample. It is rich in nitrogen, oxygen, and carbon. It is a complex molecular structure, a kind of cosmic glue that bound the asteroid's loose debris together. "

"Generally, genetically modified organisms are organisms, for example plants, animals or microorganisms, which can be said to have been created by humans as a result of changes within their genome. In the case of traditional transgenesis, this involved simply transferring foreign genes. And the key here is that these are organisms that would not have had a chance to arise on their own. "

"Regarding the potato, an interesting example that was used in engineering was the creation of a potato that produces casein, i.e., milk protein, in its tubers, which is a very interesting solution from a dietary point of view. "

"Another interesting change that was attempted to be introduced was, for example, the Arctica strawberry variety. We all probably like strawberries, but unfortunately, strawberries are not particularly frost-resistant, although there are already year-round varieties, so the gene encoding AFP, or antifreeze protein, from an arctic fish was transferred to this strawberry. "

"This gene codes for a protein that causes, when a larva of some pest eats such a plant with this protein, it leads to the perforation of the digestive system of such an animal. And it simply dies. This means we no longer need to use pesticides, because the plant itself is able to defend itself against such an invasion. "

"India has been implementing its grand three-stage energy plan for years, which is intended to culminate in thorium reactors. They are now in the second phase, but it is progressing quite slowly. "

"A new article has been published in Physical Review Letters, which in the world of physics is the equivalent of the Champions League. It is not a niche preprint, but a serious theoretical proposal. "

"In theories of quantum gravity, the graviton is the hypothetical elementary particle that mediates the force of gravitational interaction. It is a quantum of gravitational wave energy. "

"Well, today even such constructions are appearing. They cannot be as big as Gundams or something, because we would need some unimaginable materials that would be very strong. Due to the fact that, you know, when you increase something, its size, its surface area grows. The mass also grows very quickly, and in fact, the strength of the components starts to be too small to have such a, you know, Gundam or a big one, I don't know what from your time, from those big robots, there was G-Force, they had those from your time, from my time it was Gigant ze Stali in the 30s, which Gigant ze Stali could walk, it would have to be made of quite interesting materials. "

"This casing, it flies, it flies, this casing is a small piece of the projectile. You don't need, you don't need to have any casing, so you don't need to have a mechanism that, for example, removes these casings differently, because this is the entire projectile that flies, but a part is empty. Because there was an explosive charge that caused the projectile to fly out, as if pressed around from something. This is quite a strange construction if you look, for example, at this very picture on Wikipedia. There is such a caseless projectile, and in this way, the point was that such a magazine could simply offer more projectiles for such a marine. "
