David Gross, Nobel Prize in Physics: ‘The chances of humanity living 50 more years are very low’

The American scientist, winner of the Nobel Prize in Physics in 2004, maintains his vocation for exploring the unknown, although his reflections have also extended to the future of humanity.

“Physics is always a gamble; it is a game of exploration. That is where its charm lies. We never know with certainty what will happen. Sometimes we theorists can anticipate, but nature is the final judge,” Gross stated, as indicated by ‘AS’.

The physicist has also expressed a broader concern about the human future with a blunt phrase: “The chances of humanity living 50 more years are very low.”

From fundamental particles to risks for humanity

Gross’s public concerns have extended in recent years beyond the traditional problems of theoretical physics.

The scientist has also addressed the risks associated with human decisions, international tensions and the stability of global systems.

His warning about the possibilities of humanity’s survival is part of that change of scale in his reflections.

The approach transfers concepts such as risk, probability and behavior of complex systems from the scientific field to issues related to political organization and relations between powers.

Gross’s career thus connects two different areas of analysis: first, the study of the forces that operate on the smallest scales of matter and, subsequently, a public reflection on the risks that can condition the future of human societies.

The work that led David Gross to the Nobel Prize in Physics

Born in the United States in 1941, Gross developed his career within theoretical physics and was linked to academic institutions such as Princeton.

During the 1970s he participated in research that advanced the understanding of the behavior of quarks, elementary particles related to the structure of protons and neutrons.

Together with Frank Wilczek and H. David Politzer, Gross contributed to the discovery of so-called “asymptotic freedom.”

The phenomenon establishes that the strong interaction between quarks weakens when these particles are at extremely small distances.

The finding became a fundamental element for the development of quantum chromodynamics, the theory used to describe the strong interaction between quarks and gluons. For these contributions, Gross, Wilczek and Politzer jointly received the Nobel Prize in Physics in 2004.

After that recognition, Gross continued working in theoretical physics and participating in scientific discussions related to issues such as string theory and the search for frameworks capable of jointly explaining the fundamental forces of nature.
