"Everything beyond this horizon moves relative to us at an apparent speed greater than the speed of light due to accumulated expansion. If any object or galaxy crosses this invisible line, no information, no radio signal, no light ray will be able to return to our sphere of influence. "

"Up to 94% of the observable universe is already irrevocably beyond our reach. Think about it for a moment. This number can be paralyzing. "

"Future astronomers, who will be born on planets around our dying stars in 100 or 200 billion years, will look at the night sky and see absolutely nothing beyond the stars of their own galaxy. "

"The cosmic background radiation, which today allows us to study the birth of the universe and the Big Bang, will be stretched to such an extent that its detection will become physically impossible. All material traces of other galaxies will disappear. "

"Over hundreds of billions of years, the cosmic event horizon will approach an observer located in the Local Group. Subsequent large galaxy clusters, such as the neighboring Virgo cluster, will successively cross these lines of no return. Their light will greatly diminish, their redshift will reach extreme values, until they finally fade away from our instruments forever. "

"Everything outside this small local club of several dozen galaxies will be irrevocably carried away by a powerful current of expansion. Our accessible cosmos will shrink to this one connected structure surrounded on all sides by an infinite, impenetrable, and empty abyss. "

"Most of these objects are already far beyond our event horizon. We only see them because their light was emitted billions of years ago, when the universe was much smaller and galaxies were physically closer together. But today, at this very moment, as you listen to these words, these places are already irretrievably lost to us. "

"When some sudden natural disasters occur, for example, the reaction time of emergency services decides everything. Traditional observation methods from the ground level or even from helicopters, well, at such moments are limited by some smoke, if it's a forest fire, for example, some range, destroyed road infrastructure, we are not able to get to the place. And then satellite Earth observation focused on such crisis response, that is, on collecting data that allows us to react here and now and reduce the effects of this crisis, becomes indispensable. "

"Specialized satellites equipped with synthetic aperture radars orbit above our heads. They can indicate to rescuers which roads are passable and which areas have been completely cut off from the world. In the case of, for example, gigantic forest fires, thermal imaging satellites will immediately locate hotbeds, directions of fire spread, enabling firefighters to precisely plan water drops, for instance. "

"These objects are gravitationally bound to each other so strongly that the global expansion of the universe is unable to separate them. On the contrary, the Milky Way and Andromeda are currently rushing towards each other and perhaps in a few billion years they will collide, initiating a spectacular dance that will end with the formation of one giant elliptical megagalaxy. "

"And this leads us to the conclusion that a photon emitted today from a distant star will literally never reach our Local Group. "

"In an expanding universe, the speed of expansion reaches – and even exceeds – the speed of light, preventing signals from traveling to some regions. A cosmic event horizon is a real event horizon because it affects all kinds of signals, including gravitational waves, which travel at the speed of light. "

"Objects at the far edge of the universe can have whatever speeds they want, because they're far away. Any light emitted RIGHT NOW past that distance will NEVER reach us, ever, no matter how long we wait. And an accelerating universe dominated by dark energy makes this even worse. "

"We are de facto trapped in our cosmic solitude in a unique area where local forces of matter attraction are temporarily able to win a deadly battle with the all-expanding dark energy. "

"When the space between two points expands at a speed greater than light, there is not much possibility of a causal connection between the beginning and end of such a tunnel or a warp bubble trajectory in which we would travel. "

"According to available reports, many meteorite fragments have already been found in the Guls district of Koblenz, which will allow researchers to determine its origin. Although German media reported damage to many houses. No one was injured in this incident. The largest discovered fragment reportedly pierced one of the roofs, creating a football-sized hole. "

"A meteorite hit the roof of a house after thousands of people observed a stunning fireball cutting across the sky over Western Europe. In Koblenz in western Germany. Sunday evening, March 8, the International Meteorological Organization recorded over 2800 fireball observations, and dozens of video recordings were published on social media. "

"It turned out that unfortunately, by bad luck, a human settlement appeared in the path of the meteorite, i.e., the matter that fell to Earth, and people reported finding some small, tiny fragments of rocks that fell from the sky. And one of the houses had the misfortune that the meteorite simply hit its roof. "

"Physics draws for us a completely different, rather harsh map of reality, on which the cosmic event horizon appears as a hard physical barrier, and not a technological obstacle that can be overcome with a better engine or a more powerful energy source. "
