A strange form of life can shine deep inside stars, physicists say

When searching for signs of life in the universe, we look for very specific things, based on what we know: a planet like the Earth, in orbit around a star, and at some distance that liquid surface water. allows for. But, there, there may be other forms of life, nothing that we have ever imagined before.

Just as we have extreme-planets on Earth – creatures that live in the most extreme and seemingly insurmountable environment, the planet has to offer – so there can be extremes in the wider universe.

For example, species that can form, grow and grow the interiors of stars. According to new research by physicists Luis Accordocci and Eugene Chudnowski of the City University of New York City, such a thing is actually – hypothetically, at least – possible.

It all depends on how you define life. If the main criterion is the ability to encode information, and the ability for those information carriers to self-replicate faster than they disintegrate, then imaginary monoscope particles are sent to cosmic strings – cosmic necklaces – stars. Can form the basis of life inside, much like DNA and RNA form the basis of life on Earth.

“Information stored in RNA (or DNA) encodes mechanisms of self-replication,” Chudnowski told ScienceArt.

“This would have originated before the large-scale formation of random RNA sequences unless a sequence was capable of self-replication. We believe that a star would have a similar process with defeat, leading to self-replication. Can be a steady process. ”

Strings and monopoles are thought to have emerged in the early Universe, as it cooled off the Big Bang, and the quark-gluon plasma particle soup underwent a symmetry-breaking phase transition and condensed into the case. – like liquid in condensing vapor.

Although we have yet to detect cosmic strings (one-dimensional linear objects) or monopoles (elementary particles with only one magnetic pole), a lot of thought has gone into how they might behave.

In 1988, Chudnowski and his colleague, Alexander Wilenkin, theoretical physicist at Tufts University, predicted that cosmic stars could be captured by stars. There, the turbulence will stretch the string until it forms a network of strings.

According to the new study, cosmic necklaces can form in a sequence of symmetry-breaking phase transitions. In the first phase, monopoles are produced. In another, wire.

It can produce a stable configuration of a monopole bead and two wires, which in turn can bind to one-, two- and even three-dimensional structures – much like atoms involved in chemical bonds, researchers say Have to say

One-dimensional defeat would be unlikely to carry information. But more complex structures can potentially occur – and they can survive to replicate longer, feeding off the fusion energy generated by the star.

“Compared to the lifetime of a star, its lifespan is an immediate spark of light in the dark. Important is that such a spark manages to produce more sparks before it goes away, thus providing a longer life of the species Is, ”the researchers write.

“The complexity that develops through mutation and natural selection increases with the number of generations that pass. As a result, if the lifetimes of self-replicating atomic species are as short as the lifetimes of many unstable composite atomic objects, they rapidly increase. Can move towards greater complexity. ”

Hypnotically speaking, it is possible that such a life-form could develop intelligence, and perhaps even a serious smart one, says Chudnowski.

What such a species looks like is a feast for the imagination. But we do not need to know what they like to find signs of their presence. Because such organisms will use some of the energy of their host stars to survive and propagate, which can host faster cooling stars than stellar models that researchers call “nuclear life” Can.

Many such stars have been seen, and their slightly accelerated cooling is still a mystery. Wrongly retarded stars can also be a good place to look without explanation, such as – EPIC 249706694. Researchers are careful to note that these wires would have a very long bow to attract to connect them to atomic life. But there are interesting inconsistencies. And also interesting possibilities.

“As they are evolving very quickly, they could have found a way to explore the universe beyond their star, as we have done,” Chudnowski told ScienceArt. “They can establish communication and travel between stars. Maybe we should look for their presence in space.”

This is all highly theoretical, but wild ideas can be a good way to make new discoveries. The researchers plan to continue their line of investigation by developing simulations of cosmic defeat in the stars. It might not lead us to glowing aliens – but even if it doesn’t, it can give us a better understanding of cosmic strings and monopoles.

And, honestly? It’s just a really fun thing to think about.

“It’s a fascinating idea that the universe can be packed with intelligent life that’s so different from our lives that we failed to recognize its existence,” Chudnowski said.
