Looking for signs of life in the Universe is based on a few patterns and elements. Scientists tend to look for planets like Earth, in orbit around a star, and most importantly, at a distance that lets liquid surface water. But, are all of these enough to find any signs of life?
There could be other forms of life out there that don’t look like anything that scientists have ever imagined before. Like the extremophiles here on our planet, there could be extremophiles, too, out there in the Universe.
According to a new study, species that can develop, evolve, and live in stars’ interiors can be (hypothetically) possible. Here is what you need to know.
Life Inside a Star and Other Points of View
Hypothetical monopole particles threaded on cosmic strings, also known as cosmic necklaces, could develop the basis of life inside stars. Such a process is somehow similar to how DNA and RNA create the foundation of life here on Earth.
Almost three decades ago, Eugene Chudnovsky, a physicist at The City University of New York, and his colleague, Alexander Vilenkin, a physicist at Tufts University, foretold that cosmic strings could be captured by stars. Chudnovsky explained: “Information stored in the RNA (or DNA) encodes the mechanism of self-replication.”
According to recent research, cosmic necklaces could develop in a sequence of symmetry-breaking stage transitions. In the first phase, monopoles appear. In the second one, strings.
Furthermore, such a thing can produce a stable configuration of one monopole bead and two strings. They could connect and create one-, two-, and perhaps three-dimensional structures (similar to atoms joined by chemical bonds).
More complex structures could carry information. They could also last long enough to replicate, feeding off the fusion produced by the star. The researchers state: “If lifetimes of self-replicating nuclear species are as short as lifetimes of many unstable composite nuclear objects are, they can quickly evolve toward enormous complexity.” Chudnovsky believes that such life-form could develop also intelligence.
Do Stars That Host Such Life-Form Exist?
Several such stars have been spotted, and their slightly hastened cooling is puzzling scientists’ research. Stars that dim unevenly without any reason could be a great place to look, too, such as EPIC 249706694.
However, the scientists are careful to note that to associate these stars to nuclear life would be a non-ending bow to draw. But as long as there are infinite possibilities, the scientists’ work is never-ending.
