"The largest gravitational anomaly of the local Universe is hidden in a place that is practically impossible to see from Earth. It lies in an area of the sky blocked by the disk of our own galaxy. "

"The space inside the cosmos is expanding and, what's worse, according to some observations, it seems to be accelerating due to the action of a still incomprehensible energy called dark energy. "

"Witnesses reported hearing numerous explosions as a cosmic rock broke up in the atmosphere, scattering fragments across the federal state over Reni Apalaty over western Germany. Yes, it is quite common that when such a larger object enters the Earth's atmosphere, the temperature gradient is so enormous. Warmer on the outside, still cooler somewhere inside, that various structural cracks, delaminations, internal structure may not withstand such a collision with the Earth's atmosphere and an explosion simply occurs, yes, the breaking up of such a piece of rock, ice or anything else entering the Earth's atmosphere. "

"Earth, as we know, is a planet. Besides Earth, there are more planets in our solar system. Besides our solar system, there are more star systems that make up an entire galaxy. However, there are also countless galaxies. "

"Therefore, due to the limited speed of light, we only see a bubble around us with a radius of approximately 13 billion years. "

"Sagittarius A* is the name of a radio source at the center of our galaxy. It lies in the constellation Sagittarius and for years has been the prime suspect for being a supermassive black hole. "

"The Milky Way's dark matter halo appears to be powerful. It has a mass 10 times greater than all the visible matter in our galaxy and extends far beyond its visible boundaries. "

"Fermions are a family of particles that include, for example, electrons, protons or neutrons, and matter that we can touch is built from them. A key feature of fermions is that they are incredible individualists. They are governed by a quantum mechanical rule called the Pauli exclusion principle. "

"With a radius of about 700,000 km, it absolutely dominates the solar system. Let's use a simple analogy. If the sun were the size of a standard football, our Earth would be 109 times smaller. It would resemble a peppercorn just 2 mm wide. What's more, if we summed the mass of all the planets in our system, the sun would still be 743 times more massive than all of them combined. "

"This diagram, developed independently in the early 20th century by Danish astronomer Einar Hertzsprung and American researcher Henry Norris Russell, compares a star's temperature with its brightness, i.e., luminosity. A distinct band called the main sequence runs through the very center of this diagram. This is where most stars spend the vast majority of their lives. "

"Our Sun is in the middle of this diagram, being a fairly average main-sequence star of spectral type G. The letter G determines its classification based on temperature and color in the OBFGKM system, where O means the hottest objects and M the coolest. Red dwarfs are usually in this M category. Our star has a surface temperature of about 5778 Kelvin, which gives it a characteristic yellow-white hue. "

"The brightest stars are usually also the most massive. A good example is Bellatrix, the 26th brightest star in the sky, forming the left arm of the Orion constellation. It belongs to type B, one of the brightest classes, and its surface temperature is about 22,000 Kelvin, making it almost four times hotter than our sun. It is also almost nine times more massive. "

"And the truth is, of course, that we are constantly making a new studio. Well, we have already moved to this new place. Technically speaking, most of these rooms are functional, but we still need to finish some things. Acoustics still await us here, to improve them as much as possible. For now, it's good enough, as they say, but of course, it will be even better. "

"These gigantic structures, which are being discussed today, have received an official and very apt name in the scientific world: odd radio circles, in English from Radio Circles, and simply ORC for short. These are objects that seem to combine absolutely everything that we simply do not yet understand in the universe. "

"ORC circles are visible in the radio band, so there are obviously not many colors there. Radio waves, as we know, are a type of electromagnetic radiation. They are a phenomenon of exactly the same nature and family as sunlight entering through a window, or X-rays used for imaging and scans. Yes, the difference lies in the wavelength. "

"Despite this, fluctuations in methane levels are periodically detected in its thin atmosphere, which may be a sign of ongoing biological activity deep underground. "

"Based on these photometric microscopic dimmings, we determined that there are billions of such planets in the galaxy. In the Milky Way alone, tens of millions of objects orbit within the ecosphere, where a delicate thermal balance allows water to maintain its state of aggregation. "

"The key to this discovery was not looking at how the planet reflects sunlight, but how it shines with its own heat. Every planet, even the one frozen to the bone at the ends of the system, emits infrared radiation. "

"It all comes down to the gravitational chaos we observe in the Kuiper Belt. The Kuiper Belt is a debris field of icy rocks beyond Neptune's orbit. That's where Pluto, Eris, Haumea, and thousands of other trans-Neptunian objects live. TNOs for short. If the solar system were a calm, boring place, these objects should orbit in predictable random orbits, but they don't. "

"Dark stars are not dark at all. They can be millions of times brighter than the sun. The key is their power source. Our sun and all stars we see in the sky shine due to nuclear fusion, the joining of hydrogen atoms into helium. But dark stars would be powered by something completely different, the annihilation of dark matter. "

"Therefore, it was commonly believed that in biology, in our warm, wet, noisy bodies, quantum effects have no right to exist. And on a large scale, of course, they do not exist, which we can see, for example, by the fact that I can lift this cup. "

"The Standard Model, which is currently our best theory describing what the world is made of, is based on symmetry groups. And physicists denote these groups with the symbols U1, SU2, and SU3. "

"Linearly polarized light is ordered. All waves oscillate in one specific plane. "

"New research led by the Royal Belgian Institute for Space Aeronomy (BIRA-IASB) shows that 3I/ATLAS does not directly expose the material from which it formed. Instead, the pristine ice of the interstellar comet 3I/ATLAS lies beneath an outer layer of primordial material progressively altered by cosmic rays over billions of years. "

"Therefore, 3i atlas is not an intact time capsule. It is de facto baked. And what we see is the result of billions of years of such cosmic grilling. And this means that probably every object that comes to us from so far away will look similar. To see truly pristine interstellar matter, we would have to encounter a very young object or one that disintegrated right before our eyes, revealing its deepest interior. And by its very nature, this is practically impossible. "

"The solar wind is blowing today at a speed of 585.4 km/s. So you see, half of what that black hole [is]. And we are talking about small protons here, not a large massive object. The density of these protons is 24 protm sny, so very sparse. "

"In 2017, scientists from the Ogle project published in Nature the results of a search for free-floating planets based on several years of intensive observations of 50 million stars. So, as you can see, quite extensive observations need to be carried out to detect such a planet, precisely because we are unable to directly measure its light, but only when such microlensing occurs. "

"With at least 200 billion galaxies out there (and possibly even more), we're very likely talking about a Universe filled with around 1,000,000,000,000,000,000,000,000 planets in our observable Universe. 1 heptillion planets in our OBSERVABLE universe. "

"If the probability of life arising on one planet is extremely small, then the expected number of civilizations in the entire universe is zero. We essentially have an empty cosmos. "

"The Fermi paradox is a conflict between the argument that scale and probability seem to favor intelligent life being common in the universe, and the total lack of evidence of intelligent life having ever arisen anywhere other than on Earth. "

"And by studying the chemical composition of this primordial ice, we can learn what exact components planets, including our Earth, were made of. And this can serve as a reference point for understanding how the chemistry of space changed over these billions of years of the solar system's existence. Instead of theorizing, we would have material evidence from 4.5 billion years ago before us. "

"Refrigerator magnets are about five 5 milliTeslas, uhm. "

"Newton's Third Law of Motion, which clearly states that every action is always accompanied by a reaction that is equal in force and magnitude, arranged along the same straight line, but always oppositely directed. "

"In classical mechanics, momentum is simply the product of an object's mass and its velocity. We multiply one by the other, and we have momentum. "
