One of the most well-known people to propose that Oumuamua is a piece of alien technology rather than an asteroid was Avi Loeb, who is the Frank B. Baird, Jr. Professor of Science at Harvard University. As a result, he suggested that Harvard astrophysics student Amir Siraj examine the CNEOS database of over 1,000 fireball and meteor impact reports maintained by NASA.
A fireball that detonated near Manus Island on January 8, 2014, was one entry that caught Siraj's attention. It stood out due to its speed of over 130,000 miles per hour and the fact that it exploded much lower in the atmosphere of the Earth than other meteors. This suggested "a possible origin from the deep interior of a planetary system or a star in the thick disk of the Milky Way galaxy," according to a study led by the pair.
The study was submitted to The Astrophysical Journal Letters, but the review process was hampered by missing data from the CNEOS database maintained by the US Department of Defense, which uses the same technologies to look for nuclear explosions in the sky.
However, things changed in April of last year when the US Space Command (USSC) issued a memo confirming the findings of the pair.
Thus began a Galileo Project expedition to the Pacific Ocean to retrieve spherules of the interstellar meteorite IM1, which are spheres of size less than one millimeter. A gauge of where the trash had fallen was determined utilizing DoD information and seismology readings. The group set out with $1.5 million in funding from Charles Hoskinson, an entrepreneur who founded the blockchain company Cardano. It included Loot McCallum, a previous OceanGate Endeavors expert who had attempted to caution President Stockton Rush about the Titan sub's wellbeing issues in 2018.
David Charles Grusch, a former high-ranking intelligence official, claimed that the US government, its allies, and defense contractors have retrieved exotic vehicles that have landed or crashed, both partially and completely, days before Prof. Loeb left for Papua New Guinea in June. The art are depicted as non-human in beginning.
Loeb wrote, "I believe that it is easier to obtain extraterrestrial facts on the ocean floor than from the government."
On June 14, the team and the aluminum Silver Star vessel set out for the meteor's landing zone, 52 miles north of Manus Island in Papua New Guinea.
"There are around 850 communicated in dialects in Papua, the most semantically different put on The planet," Prof Loeb composed on Medium. " However, we will add a new language to this location if the expedition finds a device with an alien inscription.
A three-foot-wide magnetic sled was dropped to 1.2 miles below the surface of the ocean a few days later, and the ship pulled it around a six-mile-wide area. A filter with a mesh size of a third of a millimeter was used to sift through the tiny volcanic particles and examine the larger ones under a microscope after a week of frustration. The metallic marble of sub-milligram mass and size was discovered at that point. Within a few hours, more IM1 spherules made of a steel and titanium alloy stronger than those in other meteorites were found.
Loeb stated, "One of them looked like Earth, and many of them looked like gold."
According to Prof. Loeb's calculations, two of the spherules have an age 14 billion years older than the universe. It's trusted that proof of the shooting star's interstellar beginning will be found before long when they are dissected at the Harvard School Observatory.
According to Professor Loeb, the team is planning a second expedition in the spring of 2024 to look for a larger IM1 relic. The disclosure will be an extraordinary guide in uncovering the meteor's regular, or mechanical, beginning.
I focused on theoretical astrophysics throughout my career. I've decided to lead this expedition because it answers a fundamental question that will have a big impact on humanity's future: Is it just us?' Loeb composed.
