Harvard physicist Abraham Loeb isn’t the only renowned scientist to believe that interstellar asteroids may be alien spacecraft or the remains of spacecraft that have been destroyed or abandoned.
Scientist BPEmbaid, a physicist at the Central University of Venezuela, has published a new study in which he claims that the reason many meteorites contain the same metals produced in the laboratory by scientists on Earth is that they are d extraterrestrial origin.
In other words, these metals could be the technology signatures that SETI astronomers use to search for signs of alien technology on exoplanets and around other stars.
In his article titled “The jadeite and brezinaite meteorite mineral puzzle,” published in the arXiv Science Archive, BP Embaid, a research professor of condensed matter physics and a specialist in high-precision analytical techniques for the study of minerals , geological samples and alloys, applied his analytical techniques to two meteorites found in India in 1852 and in Yemen in 1980.
“The genesis of these meteoritic minerals could require a controlled and sophisticated process not readily found in nature,” he explains.
“It is therefore important to be open-minded, even provocative, to consider the following question: are these meteoritic minerals samples of extraterrestrial technofirms? explains Professor Embaid.
“The synthesized sulphides mentioned above do not occur naturally on Earth and have been detected as minerals in meteorites years after the first synthesis…..
FeTi2S4, first synthesized in 1968, then detected in 1974 as a jadeite mineral in the Bustee meteorite and in 1995 in the Kaidun meteorite.
The basic structure Cr3S4 was first synthesized in 1957, then detected in 1969 as the mineral brezinaite, present in the Tucson meteorite. »
In 1957, scientists searching for new electrically conductive metals combined and layered chromium and sulfur to synthesize brezinaite, a metal that does not exist in nature…at least on Earth.
Through a similar process, other scientists created jadeite. Both can act as superconductors by allowing electricity to pass through them without resistance, a feature that grew in importance when designing early computer chips.
To the surprise of scientists, astronomers studying meteorites found one that crashed in Tucson, Arizona in 1850 that contained brezinaite.
A few years later, they found the synthetic mineral in other meteorites, then did the same experiment when they found meteorites containing superconducting jadeite.
The existence of these metals in meteorites intrigued Professor Embaid, as their creation in the laboratory requires processes that are not easily replicated in nature.
“Although, of course, it is possible that there are not yet understood processes that could lead to the formation of these minerals, we can nevertheless advance a possible new interpretation in the recently emerging field: technosignatures”, emphasizes Professor Embaid.
If a mineral occurs naturally on Earth, it is part of the planet’s biological signature. If a mineral or a product is manufactured, it is part of our technosignature.
Since jadeite and brezinaite only exist in terrestrial laboratories, this places them in our techno-signature, and any extraterrestrial civilization searching for life around other stars by searching for techno-signatures could detect their signals.
Professor Embaid speculates: what if jadeite and brezinaite couldn’t occur in nature? This means that other civilizations also make them.
If so, how did they end up in the many meteorites that contain them? »
Another more familiar term for this discovery is “discontinued technology”: equipment that is obsolete or discarded after a prototype has been built.
According to online magazine The Daily Beast, Professor Embaid uses the term “derelict technology” to describe the remains of spacecraft or probes that have long since disappeared.
This may be, for example, a probe sent to another planetary system that has lost energy due to a malfunction, a collision with a space rock or normal, abnormal or normal wear and tear. unexpected.
It could also refer to a spaceship, with a living or robotic crew, that suffered the same fate and ended up breaking apart.
If any of these “discarded technologies” passed close enough to Earth, or were on a collision course with the planet, they could easily fall to the surface as meteorites.
