Scientists Find ‘Impossible’ Crystal Created by World’s First Nuclear Bomb
In an extraordinary discovery, scientists have revealed that a quasicrystal, a rare and once-thought-to-be-impossible form of matter, was created during the world’s first nuclear bomb test. This groundbreaking find, published in PNAS (Proceedings of the National Academy of Sciences), shows that the Trinity test—conducted at 5:29 am on July 16, 1945, in New Mexico—created a crystal with a five-fold rotational symmetry that defies the usual laws of crystallography. The new discovery sheds light on the extraordinary conditions produced by a nuclear explosion and may offer insights into the science of nuclear weapons and their aftereffects.
The Birth of Quasicrystals and Their Rare Formation
Quasicrystals, unlike typical crystals that have a regular repeating atomic structure, feature a non-repeating atomic pattern. The discovery of this new quasicrystal found in red trinitite—a mineral formed when the Trinity test fused desert sand and copper with intense heat—marks the first time such a structure has been identified in this context. “Quasicrystals are formed in extreme environments that rarely exist on Earth,” explains Terry Wallace, a geophysicist at the Los Alamos National Laboratory. “They require a traumatic event with extreme shock, temperature, and pressure. We don’t typically see that, except in something as dramatic as a nuclear explosion.”
The Trinity test, the first detonation of a plutonium implosion device known as the Gadget, released a massive explosion equivalent to 21 kilotons of TNT, vaporizing the test tower and surrounding materials. As the explosion generated high temperatures and intense pressure, it transformed the surrounding desert floor into green trinitite, which now contains the quasicrystal. The discovery of this crystal embedded within the trinitite reveals that extreme shockwaves and temperatures were instrumental in forming it.
A Beautifully Complex Mystery
The quasicrystal, which was identified in a tiny piece of red trinitite, displays a five-fold symmetry that was long considered impossible in natural crystals. However, the scientific community was astounded when this unusual atomic pattern was detected, offering a new layer of complexity to nuclear research. “This quasicrystal is magnificent in its complexity – but nobody can yet tell us why it was formed in this way,” Wallace explains.
While scientists are still uncertain about the exact thermodynamic processes that led to the formation of this crystal, the discovery has opened the door to future research. “But someday, a scientist or engineer is going to figure that out and the scales will be lifted from our eyes and we will have a thermodynamic explanation for its creation. Then, I hope, we can use that knowledge to better understand nuclear explosions and ultimately lead to a more complete picture of what a nuclear test represents,” Wallace adds.
The presence of this quasicrystal provides valuable insight into the conditions that occur during nuclear detonations. It may help us better understand the aftereffects of nuclear explosions and provide tools for future nuclear forensics. As the properties of quasicrystals are studied more deeply, they could reveal vital information about past nuclear tests and the long-lasting consequences of nuclear weapons.
A Tool for Nuclear Forensics
The discovery of quasicrystals in red trinitite is not only a remarkable scientific breakthrough, but it also has significant applications for understanding nuclear tests worldwide. Unlike radioactive debris or gases that decay over time, quasicrystals can persist indefinitely, offering scientists a permanent record of past explosions. These crystals could act as a powerful tool for nuclear forensics, helping to track and analyze nuclear tests, even those conducted by countries without official test records. As Wallace mentions, “Understanding other countries’ nuclear weapons requires that we have a clear understanding of their nuclear testing programs… a quasicrystal that is formed at the site of a nuclear blast can potentially tell us new types of information—and they’ll exist forever.”
This discovery has profound implications, not just for understanding the history of nuclear warfare, but also for future nuclear disarmament efforts. By examining the properties of these quasicrystals, we may be able to understand nuclear tests in a more comprehensive and long-lasting way, potentially leading to better monitoring systems and greater transparency in global nuclear activities.
