For nearly half a century, it has operated in the lightless universe, and its core contains a "forbidden element" that hardly exists in nature: element number 94, plutonium. Why is an element that shouldn't be found anywhere on Earth powering a space probe? And why did humanity create over 100 tons of this substance? This element, which the universe erased over 4.6 billion years, was revived by humanity in a laboratory. However, what they obtained was an abnormal metal that defied the laws of physics, "contracting" when heated, and a devilish substance that harbors the terror of a "demon core" that emits a pale blue flash with just a few millimeters of error. From neutron star mergers (kilonovas) to the forefront of space exploration, and the 100,000-year responsibility presented by the "Onkalo Recycle Facility" 450 meters underground, This video thoroughly dissects the true nature of the "forbidden element" created by the universe, erased by the universe, and revived by humanity, from the perspectives of physics, cosmology, and chemistry.
