This isn't about WW2, this is about the birth of the universe. We've managed to mimic it a bit, apparently in nuclear weapons.
New research published in Earth and Planetary Science Letters has analyzed the chemical and isotopic compositions of these glasses to ascertain their formation process during the nuclear event... While the composition of the environment of Hiroshima glass formation differs from that of CAIs (temperature 3,500 K for Hiroshima and 2,000 K for the solar accretion disk, 1 bar pressure for Hiroshima and 10-3–10-6 bar for solar disk, oxygen-rich environment for Hiroshima and hydrogen-rich for solar disk) and the time over which the events occurred (<20 minutes for Hiroshima versus many years for the solar disk), understanding the processes occurring during the gas-solid transition helps us uncover more about the origins of our solar system and all that has developed since.
Of course. The articles is about the beginnings of the universe.
This realisation has historical implications notwithstanding, because this factual judgement allows us better value judgements of the extremeness of nuclear weapons and armament.

What is geoscience?
Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...
