The atomic bombing of Hiroshima, Japan, by the United States in August 1945 was not only devastating at the time, resulting in the deaths of hundreds of thousands of people, but it has had long-standing impacts to the present day, particularly the elevated incidence of cancer from radiation.
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.
