Astrophysicist Avi Loeb considers that humanity’s current situation combines wars, the climate crisis and political polarization with the rapid advancement of artificial intelligence. Ele assesses that the possible discovery of alien intelligence could change terrestrial priorities. Segundo Loeb, the recognition that we are not alone in the cosmos would tend to promote cooperation among the peoples of Terra.
The researcher leads Projeto Galileo, a scientific initiative that has completed five years of activities. The team monitored millions of objects in the sky and identified that the vast majority have human or natural origins. The focus remains on searching for rare outliers. Loeb emphasizes that a single extraterrestrial object is enough to represent the greatest discovery in human history.
Projeto Galileo advances three-dimensional measurements of objects in the sky
The initiative installed three observation stations separated by 10 kilometers on Nevada. Essa configuration allows triangulation and calculation of position, velocity and acceleration of objects in three dimensions. Antes, observations from a single viewpoint generated ambiguities about apparent size and speed.
- Objetos nearby such as insects or birds may appear larger or faster than they really are.
- Arquivos of UFOs released by Pentágono in May 2026 do not include distance data.
- Sem this information, it is impossible to confirm whether the objects exceed the capabilities of human technologies.
- The Projeto Galileo seeks to fill this gap with precision instruments.
Loeb mentions that the government has satellite data with a resolution of a few centimeters, but it has not yet been declassified. The scientific team prefers not to wait and carries out independent observations.
Análise of Oumuamua and other interstellar objects remains in focus
The first known interstellar object, 1I/Oumuamua, passed through the solar neighborhood in 2017. Ele exhibited an elongated shape and non-gravitational acceleration without outgassing typical of comets. Loeb proposed that the force came from the pressure of sunlight on a very thin structure.
Três years later, the 2020 SO object showed similar behavior and was identified as the upper stage of a NASA lunar mission launched in 1966. The comparison reinforces the interest in anomalies in interstellar objects.
Loeb created Escala Loeb to classify these bodies. Ela ranges from 0, for confirmed natural objects, to 10, for alien technology that poses a threat. Tanto Oumuamua and 3I/ATLAS, detected in 2025, received a score of 4 on the scale. The anomalies are intriguing, but do not yet allow for definitive conclusions.
The astrophysicist maintains that science must follow the data. Ele criticizes the tendency to prioritize untestable theories, such as certain aspects of string theory or the multiverse. Para he, scientific progress requires curiosity and a willingness to investigate anomalies.
Expedição on Pacífico recovers fragments of interstellar meteor IM1
In 2014, the IM1 meteor entered the Earth’s atmosphere. Loeb’s team recovered small molten spheres at the estimated crash site on Oceano Pacífico. Cerca of 10% of the samples have a different chemical and isotopic composition than the Sistema Solar materials.
If confirmed, this would be the first time that scientists have analyzed material from a large object from outside the solar system in the laboratory. The finding paves the way for direct studies on interstellar composition.
Impacto of possible discovery of alien technology would divide human reactions
Loeb assesses that confirmation of artificial origin in Oumuamua or IM1 would change the view on humanity’s place in Universo. Haveria greater stimulus for space exploration. Religiões would have to adjust concepts about creation.
Mesmo thus, part of the population could maintain daily routines without major immediate changes. The researcher compares the situation to meeting a more advanced brother. The discovery would bring inspiration, despite possible initial discomfort.
Ceticismo from colleagues does not discourage search for evidence
The astrophysicist says he has learned to focus on his work, regardless of external opinions. Ele compares the scientist to a basketball player who keeps his eye on the ball.
Loeb argues that scientific responsibility lies in investigating data and anomalies. Já irresponsibility would be in maintaining untestable beliefs for decades. Ele differentiates this from religions and points to dominant currents in theoretical physics.
Fermi Paradoxo and lack of clear signs of other civilizations
The researcher suggests that advanced civilizations may not be interested in humanity. Instead of looking for primitive microbial life, astronomy should aim for higher intelligences.
Outra possibility is that these civilizations are present in our own solar system and have not yet been adequately detected. Loeb advocates more ambitious searches in the cosmic backyard.
