While high, the surface flux values are comparable to the global terrestrial production rate of methane or CH4 (1011 cm-2 s-1) and below the maximum local terrestrial PH3 production rate (1014 cm-2 s-1). We simulate the atmospheres of habitable terrestrial planets with CO2- and H2-dominated atmospheres and find that PH3 can accumulate to detectable concentrations on planets with surface production fluxes of 1010 to 1014 cm-2 s-1 (corresponding to surface concentrations of 10s of ppb to 100s of ppm), depending on atmospheric composition and ultraviolet (UV) irradiation. On Earth, PH3 is associated with anaerobic ecosystems, and as such, it is a potential biosignature gas in anoxic exoplanets. In this study, we evaluate phosphine (PH3). Beyond the most discussed biosignature gas O2, only a handful of gases have been considered in detail.
Finally, the article considers official reports and statements from the government, military, and scientists to deduce the connection between UAP and alien life.Ī long-term goal of exoplanet studies is the identification and detection of biosignature gases.
Furthermore, it explores 20 historical accounts of UAP pre-dating the invention of airplanes. Further, the article outlines examples of pilots who have experienced UAP, along with military reports on "Foo-Fighters" that can be traced back to World War I. Subsequently, it reviews 5 verified cases reported by groups of adults that fulfill specific criteria, such as third-party testimonies, consistent stories, physical evidence, polygraph tests, and follow-up government investigations. First, it examines documented accounts from children witnesses involved in 5 separate UAP encounters. This article examines multifaceted information and provides a holistic overview to assess the obscurity and controversy behind UAP.
However, it is often difficult to believe in the possibility of alien visitors due to the gap between verified UAP sightings and urban legend-like stories of aliens. While the link between Unidentified Aerial Phenomena or Unidentified Flying Objects (UAP or UFOs) and the existence of alien life has long been discredited as pseudoscience, an increasing number of government disclosures and reports on UFOs and their witnesses have recently surfaced that challenge this assertion.
