"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. "

"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. "

"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. "

"This tool will be used to map large-scale structures of the universe, studying the distribution and evolution of billions of galaxies. These gigantic datasets are to help us unravel two of the biggest mysteries of modern physics. [...] the nature of dark matter and the mechanism of dark energy. "

"Future gravitational wave detectors will be able to look directly through the plasma wall of recombination. They will bring us data from times when the universe was just an unimaginably tiny fraction of a second old. "

"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. "

"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. "

"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. "

"There will be a huge, a huge tragedy, a huge catastrophe in India or somewhere in a country similar to India. The population dresses similarly. Two powerful earthquakes in a small area, but very powerful. And one of these earthquakes will be at the epicenter of a city. At the epicenter of a city full of houses, people, skyscrapers. This could be a very tragic earthquake. There will be two very strong tremors in a small area and one tremor will hit a city, a densely populated city. "

"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.
