The Prophecies of Stephen Hawking and The Doomsday Clock

The famous astrophysicist Stephen Hawking, recognized for his brilliant mind and his fight against amyotrophic lateral sclerosis (ALS), dedicated his last years to reflecting on the future of humanity. His predictions, although bleak at times, invite us to reflect on the challenges we face as a species and the need to take action to ensure our future.

Stephen Hawking's Greatest Contributions to Science

1. Black Holes:

Stephen Hawking revolutionized the understanding of black holes by demonstrating that they are not completely black, but rather emit a small amount of radiation, known as Hawking radiation.

This theory challenged the idea that nothing could escape a black hole and opened new possibilities for the study of these mysterious celestial objects.

2. Big Bang Theory:

Stephen Hawking, together with Roger Penrose, showed that Einstein's general theory of relativity implies that the universe had a beginning at the Big Bang.

This research contributed to the understanding of the origin of the universe and consolidated the Big Bang theory as the best explanation for its evolution.

3. Quantum Cosmology:

Hawking He dedicated much of his work to the search for a theory of quantum cosmology that would unify general relativity with quantum mechanics.

Although he was unable to find a complete theory, his ideas and contributions laid the foundation for future research in this field.

Stephen Hawking was a great scientific communicator, capable of explaining complex physics concepts to a general public. His books, such as "Brief History of Time", became international bestsellers and sparked interest in science in millions of people.

According to Stephen Hawking, Humanity faces some Existential Threats:

  • Climate change: Stephen Hawking considered climate change to be the greatest short-term threat to Earth. He predicted that rising global temperatures could turn our planet into a "Venus hell," with scorching, uninhabitable temperatures.
  • Nuclear war: Although the Cold War was over, Stephen Hawking warned about the danger of accidental or deliberate nuclear war. Such a conflict could devastate the Earth and lead to the extinction of humanity.
  • Artificial Intelligence (AI): Stephen Hawking saw AI as a powerful tool with the potential to improve our lives, but he also warned of the risks of uncontrolled AI. If AI surpasses human intelligence, it could pose a threat to our existence.

But he also listed possible solutions:

  • Space Colonization: Hawking considered space colonization as a way to ensure the survival of humanity in the event of a disaster on Earth. Mars was a viable candidate for colonization, although he cited the technological and environmental challenges it entailed.
  • Sustainable Technological Development: Stephen Hawking advocated for responsible technological development that did not harm the environment. Renewable energy and the search for alternative energy sources were key to avoiding climate change.
  • International cooperation: To confront global challenges such as climate change and the nuclear threat, Hawking called for greater international cooperation. Only through joint work and diplomacy could lasting solutions be found.

Stephen Hawking's predictions, although alarming, are not inevitable. His objective was to raise awareness about the dangers that threaten humanity and motivate us to take measures to avoid them. His legacy invites us to reflect on our future, to make responsible decisions and to work together for a better tomorrow.

The Apocalypse Clock: A Symbolic Clock for Humanity

El Doomsday Clock is a symbolic clock created in 1947 by the Science and Safety Board of the Bulletin of Atomic Scientists at the University of Chicago. Your goal is represent the danger facing humanity due to nuclear, climate and other threats.

How It Works

The midnight of the Clock represents the total and catastrophic destruction of humanity. Every time the minute hand approaches midnight, it seeks to represent a growing threat. When it moves away from 00:00, it is an indication that the global risk reduced.

Who decides the position of the Clock?

The decision to adjust the Clock is made by the Bulletin's Science and Safety Board, composed of scientists and experts with knowledge of the risk that can lead to a catastrophe. These scientists meet each year to evaluate the global situation and determine whether the Clock's position should be adjusted.

What is the current position of the Clock?

As of today, the Doomsday Clock is 90 seconds midnight. This is the closest position to midnight since 1953, indicating that humanity is in a moment of great danger.

Why is midnight so close?

  • The Clock's proximity to midnight is due to a series of factors, such as:
    • The war in Ukraine and the risk of nuclear escalation.
    • Climate change and its increasingly devastating effects.
    • The development of new technologies, such as artificial intelligence, that could be used for good or evil.

The Doomsday Clock is not an inevitable forecast, but a advertisements, a tool that invites us to reflect on the dangers we face as a species and take measures to ensure a better future.
