The Drake equation is a probabilistic argument used to estimate the number of active, communicative extraterrestrial civilizations in the Milky Way Galaxy.
Extraterrestrial life, colloquially referred to as alien life, is life that may occur outside of Earth and which did not originate on Earth. No extraterrestrial life has yet been conclusively detected, although efforts are underway. Such life might range from simple forms like prokaryotes to intelligent beings, possibly bringing forth civilizations that might be far more advanced than humankind. The Drake equation speculates about the existence of sapient life elsewhere in the universe. The science of extraterrestrial life is known as astrobiology.
The Fermi paradox is the discrepancy between the lack of conclusive evidence of advanced extraterrestrial life and the apparently high a priori likelihood of its existence. As a 2015 article put it, "If life is so easy, someone from somewhere must have come calling by now."
Panspermia is the hypothesis, first proposed in the 5th century BCE by the Greek philosopher Anaxagoras, that life exists throughout the Universe. It is thought to be distributed by space dust, meteoroids, asteroids, comets, and planetoids, as well as by spacecraft carrying unintended contamination by microorganisms. Panspermia is a fringe theory with little support amongst mainstream scientists. Critics argue that it does not answer the question of the origin of life but merely places it on another celestial body. It is also criticized because it cannot be tested experimentally.
The Great Filter is one possible resolution of the Fermi paradox. It posits that in the development of life from the earliest stages of abiogenesis to reaching the highest levels of development on the Kardashev scale, there exists some particular barrier to development that makes detectable extraterrestrial life exceedingly rare.
Nalin Chandra Wickramasinghe is a Sri Lankan-born British mathematician, astronomer and astrobiologist of Sinhalese ethnicity. His research interests include the interstellar medium, infrared astronomy, light scattering theory, applications of solid-state physics to astronomy, the early Solar System, comets, astrochemistry, the origin of life and astrobiology. A student and collaborator of Fred Hoyle, the pair worked jointly for over 40 years as influential proponents of panspermia. In 1974 they proposed the hypothesis that some dust in interstellar space was largely organic, later proven to be correct.
Planetary habitability is the measure of a planet's or a natural satellite's potential to develop and maintain environments hospitable to life. Life may be generated directly on a planet or satellite endogenously or be transferred to it from another body, through a hypothetical process known as panspermia. Environments do not need to contain life to be considered habitable nor are accepted habitable zones (HZ) the only areas in which life might arise.
The Kerala red rain phenomenon was a blood rain event that occurred in Wayanad district region of Malabar on Monday, 15 July 1957 and the colour subsequently turned yellow and also 25 July to 23 September 2001, when heavy downpours of red-coloured rain fell sporadically on the southern Indian state of Kerala, staining clothes pink. Yellow, green and black rain was also reported. Coloured rain was also reported in Kerala in 1896 and several times since, most recently in June 2012, and from 15 November 2012 to 27 December 2012 in eastern and north-central provinces of Sri Lanka.
Abraham "Avi" Loeb is an Israeli-American theoretical physicist who works on astrophysics and cosmology. Loeb is the Frank B. Baird Jr. Professor of Science at Harvard University. He had been the longest serving chair of Harvard's Department of Astronomy (2011–2020), founding director of Harvard's Black Hole Initiative and director of the Institute for Theory and Computation within the Harvard-Smithsonian Center for Astrophysics.
Bernard Haisch is a German-born American astrophysicist who has done research in solar-stellar astrophysics and stochastic electrodynamics. He has developed with Alfonso Rueda a speculative theory that the non-zero lowest energy state of the vacuum, as predicted by quantum mechanics, might provide a physical explanation for the origin of inertia, and might someday be used for spacecraft propulsion. Haisch has advocated the serious scientific study of phenomena outside the traditional scope of science and is known for his interest in the UFO phenomenon as well as a variety of other unorthodox topics.
Thanu Padmanabhan was an Indian theoretical physicist and cosmologist whose research spanned a wide variety of topics in gravitation, structure formation in the universe and quantum gravity. He published nearly 300 papers and reviews in international journals and ten books in these areas. He made several contributions related to the analysis and modelling of dark energy in the universe and the interpretation of gravity as an emergent phenomenon. He was a Distinguished Professor at the Inter-University Centre for Astronomy and Astrophysics (IUCAA) at Pune, India.
The Journal of Cosmology describes itself as a peer-reviewed open access scientific journal of cosmology, although the quality of the process has been questioned. The journal has been closely related historically with a similar online website, Cosmology and Journal of Astrobiology and Space Science Reviews, as all three were founded by neuroscientist Rhawn Gabriel Joseph. Rhawn Joseph established the journal in 2009, published by Cosmology Science Publishers, and it was sold to Modern Cosmology Associates in 2011. Rudolph Schild is the editor-in-chief.
Vahagn "Vahe" Gurzadyan is an Armenian mathematical physicist and a professor and head of Cosmology Center at Yerevan Physics Institute, Yerevan, Armenia, best known for co-writing "Concentric circles in WMAP data may provide evidence of violent pre-Big-Bang activity" paper with his colleague, Roger Penrose, and collaborating on Roger Penrose's recent book Cycles of Time.
Biotic ethics is a branch of ethics that values not only species and biospheres, but life itself. On this basis, biotic ethics defines a human purpose to secure and propagate life. These principles are related to bioethics, and to environmental ethics that seek to conserve existing species. However, biotic ethics value more generally organic gene/protein life itself, the structures and processes shared by all the biota. These processes result in self-propagation, an effective purpose that humans share with all life. Belonging to life then implies a human purpose to safeguard and propagate life. This purpose defines basic moral values: Acts that sustain life are good, and acts that destroy life are evil. Panbiotic ethics extends these principles to space, seeking to secure and expand life in the galaxy.
Technosignature or technomarker is any measurable property or effect that provides scientific evidence of past or present technology. Technosignatures are analogous to biosignatures, which signal the presence of life, whether intelligent or not. Some authors prefer to exclude radio transmissions from the definition, but such restrictive usage is not widespread. Jill Tarter has proposed that the search for extraterrestrial intelligence (SETI) be renamed "the search for technosignatures". Various types of technosignatures, such as radiation leakage from megascale astroengineering installations such as Dyson spheres, the light from an extraterrestrial ecumenopolis, or Shkadov thrusters with the power to alter the orbits of stars around the Galactic Center, may be detectable with hypertelescopes. Some examples of technosignatures are described in Paul Davies's 2010 book The Eerie Silence, although the terms "technosignature" and "technomarker" do not appear in the book.
Milton Wainwright is a British microbiologist who is known for his research into what he claims could be extraterrestrial life found in the stratosphere.
V528 Carinae is a variable star in the constellation Carina.
Pseudo-panspermia is a well-supported hypothesis for a stage in the origin of life. The theory first asserts that many of the small organic molecules used for life originated in space. It continues that these organic molecules were distributed to planetary surfaces, where life then emerged on Earth and perhaps on other planets. Pseudo-panspermia differs from the fringe theory of panspermia, which asserts that life arrived on Earth from distant planets.
MZ Puppis is a red supergiant star in the constellation of Puppis. It has a radius of 400 R☉.
