Neutrino communication, intergalactic transit, and Astrobiology

Neutrinos to Astrovirology: Signatures

In the 20th century, the concept of terrestrial life's unity was solidified, and the 21st century saw the emergence and establishment of astrovirology. To date, life originating beyond Earth has not been identified. The singular instance where NASA investigated potential microfossils in Martian ejecta found on Earth has since been refuted. This report suggests that a more comprehensive discussion and analysis of life's biosignatures and communication methods are essential. Such approaches are crucial not only to avoid overlooking the possible existence of extra-terrestrial intelligence (ETI) but also to prevent potential human infections that could arise from extra-terrestrial contact. In addition terrestrial infections by microorganism that originally derived from Earth and were returned, require investigation due to potential mutations and subsequent increased pathogenicity.

Neutrino and EM asterometric detection of habitable exoplanets

Discovering habitable exoplanets and exomoons increases the possibility of detecting extraterrestrial life. A bilateral approach, using neutrino and electromagnetic (EM) radiation technologies, can be used to simultaneously characterize star types that generally have exoplanets and exomoons. This includes cool main-sequence, sub-giant, and red-giant stars. Additionally, supernovae, black holes, and neutron and dwarf stars, will be included to widen the investigation, since they sometimes have companions, including stars and planets. Currently, space exploration is advancing beyond the solar system and proliferating into deep space. For this expansion, sophisticated artificial intelligence (AI) is required and being developed for self-coordination and interactive regulation of the various exploratory vehicles and telescopes.

Bioinformation and Neutrino Communication

Communications among civilizations may include self-descriptive bioinformation because pathogen dynamics exist in their astrobiology and astrovirology, which could become pathogenic upon actual contact. This information is of mutual benefit, if reciprocated. However, in contrast, the strategic counter-scenario of self-hidden civilizations is also discussed. Civilizations, including extra-terrestrial civilizations have been divided and stratified into three levels, using a wide non-linear logarithmic scale. The levels are based on their energy expenditures: level 1 is at 4x10^19 erg/sec; level 2 is at 4x10^33 erg/sec; and level 3 is at 4x10^44 erg/sec. Terrestrial civilization is currently below the entry level I. Particularly advanced civilizations, which are above the highest level, may engineer interstellar travel and could move their planets across interstellar distances. Communication among civilizations has always been of keen interest. In terms of ability to communicate among advanced civilizations, neutrinos may be used for galactic and inter-galactic communication, in addition to or instead of using electromagnetic radiation. Thus, at this juncture, deliberation and debate are essential to proceed with development of civilization and communication.
