Abstract:

In recent years, the public and academic acceptance of studies concerning UFOs (unidentified flying objects), or UAP (unidentified anomalous phenomena), has drastically increased. Only 20 years ago, it was virtually impossible to discuss UAP in a scientific context. Today, top-tier media report about UAP in respectable terminology and scientific research projects with the aim to study UAP have been installed even at universities. In the first part of this paper, I recapitulate major events that indicate this attitude change. In the second part, I highlight similarities that UAP share with phen

Abstract:

Unidentified Anomalous Phenomena (UAP) have become a serious topic in the US Congress, and new legislation has been released outlining a plan for declassification for the public. There are numerous factors that could lead an individual to mistakenly think they saw a UAP, and one of those factors might be the proclivities of the personalities that observe what they think to be a UAP. This study examined the big five personality traits: extraversion, neuroticism, openness, agreeableness, and conscientiousness, as well as schizotypy traits, to see if UAP experiencers could be distinguished from p

Abstract:

The topic of “Unidentified Anomalous Phenomena” (UAP) has historically been regarded with skepticism by the scientific community. After a period of relative openness and ambivalence in the 1950s and 60s, it eventually became generally categorized as a “paranormal” concern and dismissed as a legitimate focus of inquiry. However, the issue has risen to public prominence over recent years. As such, this paper argues UAP should be redeemed as a scientific topic and given the scrutiny that such a potentially important phenomenon merits. The focus here is not assessing the nature of UAP per se but s

According to the tectonic strain theory, both earthquakes and most reports of UFOs (Unidentified Flying Objects) or odd luminous phenomena are generated by local transient changes in regional crustal stress. Because the injection (or containment) of fluids or their percolation into the upper crust can trigger earthquakes, we predicted that reports of these anomalous luminous phenomena should display temporal lags and spatial diffusion around these sites.

Through direct transmission electron microscopy observations at the atomic scale, the structures close to the brittle crack tip zones are clearly revealed. Notably, the lattice reconstructions initiated at the postcrack edges can impose additional strain on the crack tips, modifying the fracture tou

The recent observation of the anomalous Hall effect (AHE) without notable magnetization in antiferromagnets has suggested that ferromagnetic ordering is not a necessary condition. Thus, recent theoretical studies have proposed that higher-rank magnetic multipoles formed by clusters of spins (cluster multipoles) can generate the AHE without magnetization. Despite such an intriguing proposal, controlling the unconventional AHE by inducing these cluster multipoles has not been investigated.

Here, we report two different emergent quantum Hall effects in (Hg,Mn)Te quantum wells.

Abstract The extraterrestrial hypothesis (ETH), the hypothesis that an extraterrestrial civilization (ETC) is active on Earth today, is taboo in academia, but the assumptions behind this taboo are faulty. Advances in biology have rendered the notion that complex life is rare in our Galaxy improbable. The objection that no ETC would come to Earth to hide from us does not consider all possible alien motives or means. For an advanced ETC, the convergent instrumental goals of all rational agents – self-preservation and the acquisition of resources – would support the objectives of removing existen

Abstract:

The number of Unidentified Aerial Phenomena (UAP) reports by international military personnel has steadily increased in recent years. At the same time, many governments have openly begun investigating UAPs. Across the Indo-Pacific, many major powers have independently developed similar approaches toward dealing with individual UAP events. This perspective paper surveys several recent UAP events and explores how different Indo-Pacific countries address the potential threat posed by UAPs.

Abstract:

The study of Unidentified Aerospace Phenomena (UAP) requires a shift from a historical, narrative-based approach to a scientific and technology-based study. To conduct unbiased and agnostic research on UAPs, rigorous scientific study is necessary, including the collection of hard data to support credible explanations or scientifically prove the existence of unknown phenomena. Obtaining reliable and valid data requires instrumented observations, including multi-wavelength and multi-mode sensors (e.g., optical, radar, infrared). We present herein an overview of the benefits as well as the strate

Abstract:

Phenomenology as a research method is rooted in rigorous examination of first-person experiences, and identifying that which is essential to the appearance of the object. Phenomenology offers several important strengths that make it critical to include as a supplemental method to more empirical approaches. Strengths of phenomenology include the restoring of the lived world as the foundation of knowledge, moving beyond the extraterrestrial hypothesis, the exploration of absences, the discrimination between sensory perception and non-ordinary perception, exploring UAP as intersubjective experien

Abstract:

Increasingly, scientists among UFO investigators outside the mainstream seek to explain UAP (Unidentified Aerospace Phenomena) with the extraterrestrial hypothesis. Within the lab walls of safe science, astrobiologists believe extraterrestrial life exists on exoplanets but deny that aliens are visiting earth. Both work with a scientific mindset. Both believe in the “ETI myth.” But astrobiologists shun ufologists. Can we invite both ufologists and astrobiologists to enjoy each other’s company in the same laboratory?

The most important procedures about the scientific investigation of Unidentified Aerial Phenomena (UAP) using astronomy-like methods are conceptually presented and discussed, where results obtained in the past are triggering the proposal for new observational sessions using multiwavelength and multimode instruments. A special emphasis is posed on the techniques of magnetometry, photometry and spectroscopy, and on the importance of studying the variability of the phenomenon in order to try to understand the physical process that governs it, including a possible propulsion mechanism.

Abstract:

This paper provides a view of the pattern of reported Unidentified Aerospace Phenomena (UAP) in the United States associated with the military atomic weapons complex between 1945 and 1975. A set of 590 comprehensively documented UAP reports from this period were collected from select sources, including Project Blue Book. These were analyzed graphically for spatial and temporal differences between the number of incidents reported at sites within the atomic warfare complex, and control sites. Initial study site classes were: 1) radioactive materials production plants; 2) atomic weapons assembly

Abstract:

The search for extraterrestrial intelligent (SETI) and non-intelligent extraterrestrial life has recently received considerable attention in academia and international news media. Since media frames of scientific space exploration potentially influence public support and perceptions of science, the German news media’s coverage of extraterrestrial life was analyzed. The three dominant frames from 2009 to 2022 were beneficial space exploration, unidentified aerial phenomena (UAP)/extraterrestrial intelligence (ETI), and SETI risk. Two frames relied primarily on scientific sources, mainly univers

Abstract:

Abstract If a space-faring civilization embarks on a program to send probes to interstellar destinations, the first probe to arrive at such a destination is not likely to be one of the earliest probes, but one of much more advanced capability. This conclusion is based on a scenario in which an extraterrestrial civilization (ETC) embarks upon an interstellar program during which it launches increasingly sophisticated probes whose departure speed increases as a function of time throughout the program. Two back-of-the-envelope models are considered: one in which the launch velocity of an outgoing
