The movie Oppenheimer, which first aired in Philippine Cinemas on July 19, 2023, depicts the journey that J. Robert Oppenheimer took to design the first ever nuclear bomb. The physicist’s legacy with nuclear fission is a scientific milestone of destructive potential, something the world understood well when the first atomic bomb dropped on Hiroshima and ended World War 2.

Everyone then knew what a weapon can bring, but many still wonder how it works. What even is a nuclear bomb? How could it be so destructive?
A nuclear bomb is a weapon that harnesses the immense amount of energy stored within the elements of uranium and plutonium, using the destructive potential of the energy generated which is then weaponized by two methods; nuclear fission and nuclear fusion.
Nuclear fission is when the nucleus of a particularly big element, such as uranium 235, splits up into smaller and roughly equally sized atoms. This splitting would release energy, causing other neighbouring uranium 235 atoms to also split and release their energy. This splitting and energy releasing would cascade until there is so much energy released that the bomb essentially detonates into a massive fireball. All of this happens in a fraction of a second.
Nuclear fusion is another approach where two lighter elements such as tritium and deuterium – which are isotopes (or variants) of hydrogen – are forced together to form a heavier element, and the excess energy is released. This released energy then goes on to force other deuterium and tritium atoms to fuse, releasing even more energy that cascades to a point of a massive release of energy, triggering a detonation in a fraction of a second, much like fission.
Whichever the methods are, the result is a weapon of vast destructive capabilities which the world has an unfortunate abundance of. Its immense energy inspires awe as well as fear in its potential for unfathomable destruction. Oppenheimer and the rest of the world then was right to fear for the legacy. They created a fear that fortunately has yet to happen, 78 years after the first demonstration of nuclear weapons. And as we celebrate the International Day Against Nuclear Tests on August 29, let us cherish our time when nuclear weapons have not come to dominate. They have no place in this world, and we hope that it stays that way for the rest of time.
