If you are reading this, it is highly likely that youman of the 21st century, who sometimes thinks about the ultimate fate of the universe, without wishing, however, to influence it in any way. But it is also possible that you, dear reader, will become an immortal member of a galactic civilization in the distant future. Peering into the face of the cosmic apocalypse, you pause and search for relevant information in ancient records on the Internet.
What will be the end of the universe
Perhaps the future has already come, you have become a membergalactic community and now read this. Keep in mind that at the beginning of the 21st century, we were significantly limited by the current capabilities of science and technology. You have already become part of an endearing civilization star, which can tap the energy of a whole star. Who knows? Perhaps you have already found a hypothetical solution, or you will find it in the past.
Back in 2018, people did not know what kind of endexpects the universe. The first came to mind some fairly old concepts: the Great Freezing and the Great Compression. In the expanding universe, however, everything either had to expand forever, or, ultimately, shrink and narrow. If the universe continued to expand, it would have come to its thermal death. If she began to shrink, everything would shrink to a fiery singularity.
In 1979, physicist Freeman Dyson proposedseveral survival strategies. In order to resist the Great Compression, he proposed a highly developed civilization "to crack the closed universe and change the topology of space-time so that a part of it collapses and another part expands forever." Then he argued that such a developed civilization will be able to cope with the eternal expansion, but further developments have changed everything.
The fact is that in 1998, people found thatexpansion of the universe is not only happening, but accelerating. BBC author Adam Becker turned to Dyson in 2015 on this issue and Dyson said that he had slightly diminished optimism, and the most pleasant possibility was that the acceleration would gradually slow down. Otherwise, the universe will become too fragmented and cold.
In 2018, astrophysicist Dan Hooper pondereda question of the long-term survival of a galactic civilization and suggested that the destruction could at least be delayed. Just as a pending day of judgment can collect and preserve canned food, so a highly developed civilization can preserve the sun. She could pull out medium-sized stars and drag them to other areas of space for safe keeping.
If stealing stars is not your style, physicist AlanGuth, who, by the way, developed the theory of cosmic inflation, told the BBC that galactic civilization can create its own pocket universe. Run into it and save yourself from the destruction of the previous one.
These are just a few schemes that could beto use in order to avoid cosmic stagnation - and they do not imply a Big Break or Big Change, during which your beloved universe cools down due to a low-temperature vacuum bubble or suddenly burst with dense phantom energy.
Perhaps you could become stellar lords inthe distant future, but ultimately you won’t win. The universe, as far as we understand it, will exist for an incredibly long time before it changes. But after that the conditions of its existence will not be very pleasant. Hopefully, you will have several stars at your side when this happens.
