On July 16, 1945, the atom bomb was successfully tested by the United States.

During World War II, the Manhattan Project was created to continue the efforts to develop a uranium bomb. Albert Einstein himself wrote to President Franklin Roosevelt to chime in theories about the potential of such a weapon. 

In 1943, Robert J. Oppenheimer, director of Project Y at a lab in New Mexico, and his team made significant progress in the development of harnessing a nuclear explosion and the creation of a deliverable bomb. 

The next step was to put their theories to the test.

From about five and a half miles away, the scientists watched as “Trinity” –  the first atom bomb – was detonated in the New Mexico desert. Years later, Oppenheimer recalled an expression from a Hindu holy book that came to his mind after the test quote:

“Now I am become Death, the Destroyer of Worlds.”

Less than a month later, similar devices would be dropped on the cities of Hiroshima and Nagasaki in Japan, killing at least 129,000 people, and finally — and violently — ending the second World War.
