"In holographic models, entanglement can act as the threads from which space is woven. Strongly entangled regions are in a sense geometrically close to each other. If we decrease entanglement between parts of a system, the corresponding space can stretch, separate, and in extreme cases even break apart into separate fragments. This sounds like pure abstraction, but it makes deep sense. Space can be a map of informational relationships, not something primary, but something that arises from a system of quantum connections. "

"The breakthrough occurred in 1997, when Juan Maldacena proposed one of the most important ideas in modern theoretical physics, the AdS/CFT correspondence. Maldacena showed that a certain type of space with gravity, the so-called anti-de Sitter space, which is precisely AdS, can be described by a completely different theory acting on its boundary. "

"From this, the Bekenstein bound was born, an idea stating that there is a maximum amount of information that can be packed into a finite region of space. And this amount is related to the surface area of the boundary of that region, not its volume. This was the first strong signal that three-dimensional space might be redundant in some sense, that nature might not need to record everything within the volume. Perhaps its surface is enough. "

"In Maldacena's correspondence, something similar happens with physics. What looks like a space with gravity inside can be described as a purely quantum system without gravity at the boundary. This was a big 'aha' moment for theoretical physics, because if gravity appears in one description and not in another, then maybe gravity is not fundamental, maybe it is an emergent phenomenon, something that arises from deeper quantum structures. "

"Bekenstein observed that the entropy of a black hole is not proportional to its volume, but to the surface area of its event horizon, to that boundary, beyond which there is no return. "

"Population III stars were the first factories of these building materials. Without them, the universe would simply be a boring, empty space filled only with two gases, hydrogen and helium. It was Population III stars that introduced chemistry into the physics of space, transforming a simple universe into a place where life could finally exist. "

"We argue that Population III stars are the most plausible explanation for the observed He II emission, with no satisfactory alternative from other classes of sources or mechanisms. He's spectrum is essentially bare of these metals implying gas that has barely, if ever been processed inside stars. "

"Population III stars are the first stars that formed from pristine hydrogen and helium just after the universe cooled down after the Big Bang. They did not contain an ounce of carbon, oxygen, or iron. These elements simply did not exist yet. They had to be created, as it were, cooked inside these first stars. "

"We now have evidence for diverse and potentially complex organic matter, preserved in different locations on Mars and detected with different instrument suites. This suggests that organic carbon is better preserved over long time periods on Mars than we expected, given the harsh radiation environment. "

"we have proteins. I mean, we don't have them, but robins have proteins in their retina called cryptochromes. In these cryptochromes, when light falls on such a protein, two electrons are emitted that are entangled with each other. And this entanglement does not collapse, but reacts precisely to the magnetic field line. "

"SN 2024ggi was a Type II supernova event that occurred in the spiral galaxy NGC 3621... It was discovered using ATLAS on 11 April 2024 at 03:21 UTC. ... Roughly 5.8 hours after the explosion... NGC 3621 is a disk spiral galaxy about 22 Mly (6.7 Mpc) away. "

"When Voyager 2 flew past it, it discovered that the magnetic field is tilted from the axis of rotation by an incredible 59 degrees. As if that weren't enough, the center of this magnetic field is not in the center of the planet, but is shifted by as much as 1/3 of Uranus's radius towards the surface. "

"The mission concept was selected as the highest priority Flagship-class mission by the 2023–2032 Planetary Science Decadal Survey, ahead of the Enceladus Orbilander and alongside continuing work on the NASA-ESA Mars Sample Return. China is planning an ambitious two-for-one shot to the outer planets with a pair of spacecraft to launch for Jupiter and Uranus around 2030. The mission will be named Tianwen 4 and will see a larger probe destined for Jupiter and smaller spacecraft to be sent to make a flyby of distant Uranus. "

"Uranus is the only planet in our system that receives more solar energy at its poles than at its equator. And this solar light directly drives the formation of aerosols and cloud thickening, which astronomers could observe over the last 20 years, seeing how the northern pole of Uranus dramatically brightens, approaching the summer solstice, which will take place in 2030. "

"When in 2014 the results of analyses conducted by a team of researchers from the University of Hawaii were published, scattered fragments of knowledge were combined, revealing our new, cosmic reality. The truth was discovered, that we, meaning the outskirts in Virgo along with the sides, the truth was discovered, that we, meaning the outskirts in Virgo along with the structure of the Great Attractor and dozens of other distant groups lying in all directions of the Universe, are a coherent, organic, and homogeneous galactic body. "

"We understood that the momentum of the Milky Way is a forced motion, in which our extraordinary speed is derived from the towing of two gravitational forces. Only 44% of this imperative comes from the streams of the Great Attractor. The remaining 56% is the distant and overwhelming influence of the Shapley Supercluster, which slowly sucks in its direction not only our galaxy, but also the entire area of the local attractor itself. "

"Although the speed of light is finite, space itself seems not to be subject to any speed limits. The structure of the vacuum itself is not subject to the limitations set by the relativistic light limit. Therefore, space can expand at speeds greater than the speed of light. "

"The gravitational interaction of such a dark core fits observational data as well as a black hole. The orbit of the S2 star would look almost identical in both cases. And here researchers explicitly state that no decisive preference emerges between the models, whether it is a black hole or this dark matter core. Mathematics allows both possibilities. "

"When this process begins in the Sun, its radius will increase from the current 700,000 km to 300 million km. The star will grow enough to completely engulf Mercury, Venus, and probably also Earth. This transformation applies to stars with a mass of about 0.8 to eight solar masses. "

"When a star runs out of hydrogen in its core, the aforementioned hydrostatic equilibrium ends. Without energy from fusion preventing gravity, the core begins to collapse, and the collapse causes an extreme increase in pressure, which in turn raises the temperature. Eventually, the core becomes so hot that it initiates Helium fusion, introducing the star into a completely new stage of evolution. But this giant temperature also heats the outer layers of the object. They reach thermal levels that previously only existed in the center. Suddenly, hydrogen atoms in the outer shells gain the ability to fuse. This powerful new energy source forces the star to dramatically expand. The object becomes a red giant. "

"In 2024, the European XMM Newton space telescope recorded a powerful emission of X-rays coming from the core of the cloverleaf. And we must remember that X-ray radiation in space does not come from nowhere. It is usually a derivative of an environment where gases are crushed with extreme force by a shock wave, which raises their temperature to millions of degrees. "

"In 2003, Mike Brown's team discovered Sedna, a dwarf planet with an orbit so stretched and strange that it could not be explained by the presence of known planets. Then we found more objects and started to notice a pattern. Their orbits are combed in some way. Many of them are inclined at the same angle, and their perihelia, the points closest to the sun, cluster in one area. Some even orbit in the opposite direction to the rest of the solar system. The probability that such an arrangement arose by chance is, attention, 0.006%. "

"The key is a phenomenon called the Lidov-Kozai mechanism. The Lidov-Kozai mechanism is a gravitational three-body dance. Imagine the Sun, a small TNO-like object, and a massive perturbing body, in this case, our hypothetical Planet Nine. In this system, an unusual exchange of energy occurs. The orbit of the small object is not constant. Instead, it trades its parameters, so to speak. The object can give up some of its inclination relative to the system's plane. In return, it gains greater eccentricity, meaning its orbit becomes more egg-shaped, elongated. The opposite can also happen. This is a cyclic process. Planet Nine, orbiting on its distant path, slowly pumps, tilts, and stretches these orbits over millions of years. And it is this mechanism that explains why we see objects with such extreme orbits, perpendicular to the ecliptic, and even moving retrograde. Without a third massive player in this system, the math simply doesn't add up. "

"Terry Fan and Professor Goto were not searching blindly; they obviously created a profile of the sought-after object. They were looking for an object with a mass 7 to 17 times that of Earth, moving at a distance between 500 and 700 astronomical units from the Sun. They knew exactly how such an object should move against the background of stars over those 23 years. They processed millions of data points, rejected everything that didn't fit the pattern, and were left with 13 candidates. After manual verification, only one, one specific candidate remained on the field. "

"JADES-GS-z14-0 is 1,600 light years (ly) wide and very luminous. Spectroscopic analysis revealed the presence of strong ionized gas emissions, including hydrogen and oxygen. [...] Its age, size, and luminosity added to a growing body of evidence that current theories of early star and galaxy formation are incomplete. "

"A pulsar is a very dense, very compact star. Most often a remnant after a supernova explosion, it has sizes of 10, 20 k, several kilometers, but a mass, a mass greater than the mass of the sun. density at the level of nuclear density 10 to the 14 kg per cubic centimeter, these are like individual neutrons packed next to each other. "

"It turned out to be a cyclic phenomenon. And what turned out? It turned out that when celestial mechanics methods were used to fit possible configurations to these observation results, it emerged that this pulsar orbits a common center of mass with another neutron star, something invisible, hellishly dense, and very small. "

"If it's not a dumbbell, but a disk rotating axially, it won't be a source of gravitational waves, but an already distorted disk will be such a source. If it's a supernova and the supernova explodes very symmetrically, as they say, it won't be a source of gravitational waves, but supernovae most often explode in a way where there's a difference in the amount of matter going in different directions, due to magnetic fields, rotations, and so on. And at that moment, there's a pulsating star, because there's also acceleration, it pulsates and slows down. If it's a strictly symmetrical star, one that expands uniformly throughout its volume, it also won't be a source, but a star that has something called a quadrupole moment, where some parts go up and others contract, because that's usually how it looks, such a star will be a source. "

"Gravitational waves arise when the phenomenon of gravitational field pulling occurs. When mass moves, when mass moves and when it accelerates, right? This is, this is, a disturbance is created in the gravitational field, right? In this distribution of the gravitational field, as if this gravitational well, right, it starts to ripple like that and it spreads at the speed of light, right? This is, as it were, very classically derived from the general theory of relativity. "

"One line, the theoretical one, and another one that deviates. And this happens over time. Subsequent dots, as it were, form, and this observed distribution, as one might say, fits perfectly, cup for cup, with the predictions of general relativity again. "

"MeerKAT, a radio telescope with a diameter of 13.5 meters operated by the South African Radio Astronomy Observatory, detected radio absorption lines by hydroxyl radicals, namely OH molecules, from the interstellar object 3I/ATLAS. The OH absorption signal was detected in two spectral lines at radio frequencies of 1.665 and 1.667 gigahertz. "

"Radio waves have the advantage over visible light that they penetrate the densest dust clouds, and thanks to this, we were able to look directly into the gas clumps surrounding the comet, and the result is unequivocal. There is water, lots of water. If Atlas were a dry spacecraft or a worn-out alien probe, this signal simply wouldn't exist. So we are dealing with a wet, well, in quotation marks of course wet, frozen icy body, chemically very similar to comets we know from our own backyard. Water, carbon, simple compounds, the building blocks of nature, not any engineering. "
