"Alcohol, of course, in outer space is something rather, I would say, common. It's not something, my dear friends, unheard of, so especially methyl alcohol is very often accumulated in outer space. Simply in nebulae, for example, these molecules of this substance are accumulated. Well, it forms in a fairly simple way, without the need for human involvement or aliens interested in producing high-proof beverages. simply in such molecular clouds. "

"In zero gravity, things like crumbs don't just fall to the floor. Instead, the crumbs can float around the station or spacecraft and disrupt the proper functioning of equipment, which could put the crew at risk. One of the ways NASA mitigates this risk is by sending up foodstuffs like tortillas instead of sliced bread. The tortillas make a great choice for astronauts for a variety of reasons. First, they do not produce many crumbs. "

"Food in space is known for its capriciousness. Astronaut menus are carefully constructed to maximize nutritional value and caloric content, while minimizing storage, preparation requirements, and contamination risk. And then there are crumbs. But contrary to appearances, listen, it might sound funny, like, here crumbs are nothing terrible, but in space, in a closed room, in a closed environment like a space capsule, a spacecraft, they can lead to clogging filters, they can generally be very troublesome and very dangerous, so that's an element that needs to be dealt with. "

"Artemis 2 will fly to the Moon. Artemis 3 will test connections in orbit. "

"The comet is named 3I/ATLAS because it is the third (3) interstellar (I) object found passing through our solar system. "

"Radio radiation and infrared waves can penetrate thick clouds of galactic dust. They do so much more effectively than visible light photons, outlining for us at least a minimal outline of the hidden panorama of the cosmos. "

"With its ability to penetrate through atoms, X-rays enable a powerful direct probe of both gas and (∼< 10μm) dust over orders of magnitude absorption and temperatures, to provide complementary knowledge to the wealth of existing information. Infrared, radio and X-rays, however, can penetrate this dust and gas. X-rays have two interesting properties which make them unique for the study of “The Hot and Energetic Universe”. Firstly, they can penetrate and go through matter, which explains why they are used in radiology. "

"The problem is that deep within their circuits, the lion's share of our modern electronic devices requires a completely different power supply to operate, namely direct current, or DC for short. Your smartphones, laptops, microwave ovens, home Wi-Fi routers, and generally widely used LED lighting, all of them operate on direct current. "

"When star matter collapses under its own weight, under its own mass, electrons start rubbing against each other and resist. This resistance is called electron degeneracy pressure. And it keeps white dwarfs alive. If gravity is stronger and crushes electrons with protons, neutrons are formed. "

"Our knowledge of black holes can be most simply summarized as follows. They are cosmic traps from which absolutely nothing escapes, and at their very center lies a singularity, a point where all known physics breaks down. That's where space ends, and time ceases to have any meaning. "

"The early universe, right after its birth, went through a phase of extremely violent, exponential expansion, which we observe today, for example, in the relic radiation, and this expansion is called inflation in cosmology. And think of it as inflating a balloon in a fraction of a second to the size of the solar system. "

"The second problem is how to combine gravity with quantum theory. Black holes are, in this regard, an ideal case, because we know exactly what goes wrong in them and how. And this, in turn, opens up the possibility of finding a solution to this problem. The third and perhaps most fascinating problem hidden in the loss of information inside a black hole is the very nature of time. "

"The General Theory of Relativity is undoubtedly Albert Einstein's life's work and our best description of how gravity works. To understand it, we must imagine gravity not as an invisible rope pulling objects together, but as geometry. Space and time form a single elastic fabric, i.e., spacetime. "

"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. "

"The problem, however, is that Einstein's equations of general relativity predict the existence of singularities. They appear, for example, during the Big Bang, and also precisely inside black holes. What is this unfortunate singularity? It is a point where mathematics simply gives up and leaves the room. "

"In mathematics, we cannot divide by zero, and a singularity in a black hole is precisely such a division by zero error served to us by nature itself. Mass collapses to a point of zero volume, which means infinite density and infinite gravity. "

"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. "

"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. "

"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. "

"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. "

"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. "

"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. "

"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. "

"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. "

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

"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 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. "

"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. "
