A non-Earth radioactive isotope has been found in the deep crust of the Pacific Ocean, evidence of an alien “cataclysm.”
According to Science Alert, it is the isotope plutonium-224, an element with a half-life of just over 80 million years, so it could not have been on Earth since its “beginning” more than 4.5 billion years ago. The appearance of this rare isotope of an element with a name reminiscent of Pluto always goes hand in hand with iron-60, an iron isotope that has proven to be an alien “intruder.”
A research team led by physicist Anton Wallner of the Australian National University found this rare isotope in samples of sea crust nearly 1,500 meters beneath the Pacific Ocean.
According to Dr. Wallner, this plutonium-224 can be formed from supernova explosions or, more specifically, from what is considered the most violent event in the universe: the explosion of a neutron star.
Neutron stars are one of the most energetic forms of matter, so their explosions affect a large area of space. Astrophysicists also suspect that some mysterious radio bursts recently sent to Earth come from neutron star explosions in other galaxies. This explosion is therefore considered a cosmic “cataclysm.”
The mystery of this alien “death” isotope has not yet been fully unraveled, but its companion, iron-60, is consistent with 2-4 terrifying explosions that occurred just 160-330 light years from Earth. With the age of the “death” isotope, it is clear that Earth suffered an alien cataclysm in a time closer than we thought: less than 80 million years.
According to the Daily Mail, another theory is that the plutonium-224 wandered into the interstellar medium and was launched into the Solar System by a supernova explosion.
The paper published in Science confirms that examining radioactive isotopes linked to violent extraterrestrial events can help build a signaling system so we can better recognize collisions and explosions. Explosions in near space and their impact on life on Earth. Some previous studies have linked supernova explosions to mass extinction events.
