In the Universe man is not alone. The hypothesis that life is also possible on other worlds, even in a form unusual for an earthling, does not leave the scientists for a minute. Today, it is one of the deepest questions in the astronomy. And although understanding of space has expanded significantly over the past decades, many mysteries remain that are still difficult to solve. One of them is associated with the presence of building blocks that are found in the atmosphere of distant planets.
But more compelling evidence that they are capable of or are already shaping life elsewhere outside of the Earth has yet to be found. The science believes that one should look for life, but different from the earthly. There are many speculations about an alien life.
Basically, they are all associated with non-carbon-based life forms. Could Titan, for example, have nitrogen-based life, where methane replaces water? Can silicon serve as the main element? Can alien plants depend on sand, as plants on the Earth depend on carbon-rich soil? The works of the science fiction writers help to get closer to the answer. For example, back in the 80s of the last century, in his novel Dragon’s Egg, author Robert Forward suggested that an alien species could live on the surface of a neutron star in events of nuclear interactions.
And although the very idea of the novel has been disproved by the science, its direction gives the scientists new clues. They do not rule out the presence of life in complex chemical conditions, when the beginning of the DNA-like structure appeared that could allow an evolution.
Recently, a team of researchers examined the possibility that cosmic strings and magnetic monopoles could play the role of the DNA. Strings are hypothetical cosmic cracks that could have formed during a certain period of the development of the Universe. Namely, when it underwent a phase transition during the creation of matter. Monopoles are particles with only one magnetic pole. There is no evidence of their existence either.
Assuming that monopoles can form groups along cosmic strings, and that stars can trap those strings, the scientists created an alleged pattern of turbulent motion of nuclei in stars that encode and reproduce information. And perhaps it is a certain month for starting a new life.
But for the most part, such a theory is unlikely and unprovable nor if there are any evidence to support nuclear life. The main task that the scientists are trying to figure out now is the presence of life forms inside distant stars. That idea has a number of hypothetical assumptions that require a detailed research.
