World's first nuclear explosion forged an 'impossible' crystal

At 5:29am on July 16, 1945, the first nuclear explosion, the Trinity test, vaporized the New Mexico desert and produced trinitite. The plutonium implosion device known as “The Gadget” released energy equivalent to 21,000 tonnes of TNT, disintegrating the 98-foot test tower and copper infrastructure. The blast fused tower materials and desert sand, then rained molten blobs that solidified into a new mineral. Scientists later found that trinitite can contain crystal structures that should not form on Earth. A study investigated red trinitite containing tower and equipment metal traces and identified clathrate structures made of silicon cages trapping calcium atoms. These crystals require extremely specific conditions and are rarely found in nature, with energies far above feasible natural formation conditions.

"At 5:29am on July 16, 1945, humanity entered a dangerous new era as the world's very first nuclear explosion blossomed over New Mexico. As the blast, known as the Trinity nuclear test, vaporised the surrounding desert, it also created something incredible. Scientists have discovered that the ferocity of this nuclear explosion forged an 'impossible' crystal. Researchers say this bizarre substance is like nothing else on the planet and is the first of its kind to have been formed by a nuclear blast."

"During the Trinity test, engineers from the Manhattan Project detonated a plutonium implosion device known simply as 'The Gadget'. The energy released was equivalent to 21,000 tonnes of TNT, and instantly disintegrated the 98-foot (30 metre) test tower and copper infrastructure. The nuclear fireball swept up and fused the tower, measuring instruments, and desert sand, raining down molten blobs of an entirely new mineral known as Trinitite."

"Once prized as a morbid souvenir, scientists have now found that this strange mineral contains crystal structures that should have never been able to form on Earth. In a new paper, published in Proceedings of the National Academy of Sciences, researchers investigated crystals that formed inside a particularly rare red form of Trinitite, which contains traces of metal from the tower and equipment. Inside a chunk of red Trinitite, the researchers uncovered a type of crystal structure called a clathrate."

"These are made up of silicon atoms arranged in a cage-like lattice, each trapping a single calcium atom inside. These structures are very special because they require extremely specific conditions to form, and are rarely found in nature. Co-author Professor Michael Widom, of Carnegie Mellon University, told the Daily Mail: 'Their energies are far above what would normally be feasible to form at naturally occurring temperatures and pressures.' Professor Widom adds that it is 'unlikely that they could even be formed in a laboratory'."
