IM1 was detected over the South Pacific, off the northern coast of Papua New Guinea, in 2014. It is also called CNEOS 20140108. The meteor had an estimated mass of 460 kg and was between 80 cm and 1 m (2.6-3.3 feet) in diameter. A few milligrams of material that have been found. Many larger multi-kilogram pieces could still be found.
If natural, IM1 could be the product of a planet with a magma ocean and an iron core, where elements with affinity to iron sink towards the core and other elements left behind in the planet’s crust reflect the “BeLaU” abundance pattern discovered in their new scientific paper.
In an unprecedented gesture, the arXiv administrators chose to highlight the paper with a dedicated video featuring a summary of the paper’s findings, read by artificial intelligence (AI).
If IM1 was technological in origin, then the enhanced abundance of heavy elements in “BeLaU”-type spherules could have resulted from the fact that LaO over Mo or W sulfide substrates are promising materials for 2D semiconductors in nanotech fabrication. Uranium is used in fission reactors.
Radioactive isotopes in the “BeLaU”-type spherules can be used as clocks, based on their known half-life and the relative abundance of daughter and parent nuclei.
The abundance of beryllium would accumulate from interstellar cosmic-ray collisions.
Measuring the duration of IM1’s journey and multiplying it by its known velocity outside the solar system, could inform us of the distance and direction of its source star.
They will try to use AI code to simulate the properties of alloys based upon the mixture of elements they have found.
They have mapped where the excess IM1 spherules were located relative to the background material in the control regions that they surveyed. They can forecast where large pieces could have landed based on their size. Smaller objects slow down faster because of their larger area-to-volume ratio.
