In 1950 two scientists wondered if possible a nuclear bomb of 10 gigatons. Its results are hidden locked up

On October 30, 1961, a Soviet bomber furrowed the skies of the Arctic towards Novaya Zemlya. Under his fuselage he hung an artifact the size of a bus: an unprecedented nuclear pump. At 11:32, the called TSAR pump He released. A parachute slowed its fall, allowing the plane to move away. Then, a detonation illuminated the sky with a fireball of almost 10 kilometers in diameter and a fungus -shaped cloud that amounted to more than 65 kilometers. The show was surreal: the pump, With 50 megatones explosive (more than 3,300 times that of Hiroshima), became a symbol of the Nuclear madness.

But it could be much worse.

The awakening of a new era. With the atomic bombardment of Hiroshima and Nagasaki In August 1945, the world changed irreversibly. Those bombs, 16 and 21 kilotons respectively, they marked the beginning of the destructive power without a paragon of Nuclear weapons. However, despite their fearsome capacity, these weapons were only the first step towards a much more sinister technological escalation.

What would later transcend the most reckless imagination. The most powerful pump ever detonated would be That Soviet tsar of 50 megatones, although designed to reach 100. However, the most disturbing thing is that this was not the summit. In hidden, the United States had still planned More huge.

The “Super” concept. Hiroshima and Nagasaki bombs were based In fission: A chain reaction in which heavy nuclei are divided releasing energy. But as we said, in parallel to their development, some scientists imagined a second stage: The fusion.

This implied union of light nuclei (as deuterium and tritium) to form a heavier one, releasing even more energy. It happens that this reaction required an initial fission explosion to activate, which would give rise to the concept of the Hydrogen pumps. In the 1940s they were just a theoretical speculation … but everything changed very soon.

Communism comes. After the detonation of the First atomic bomb Soviet in 1949, the United States accelerated its thermonuclear programs. The fear of communism, enhanced by the revolution in China that same year, made the National Security Council recommend quadruply military spending.

In that context, the figures of Edward Teller and Stanislaw Ulam appear, who devised The design that even today supports the H bombs. In 1952, the “Mike” test of Operation IVY demonstrated for the first time the Thermonuclear principle: an explosion of 10.4 megatones (500 times Nagasaki) that left a crater of 1,900 meters wide.

Despite such force, that was not enough for Teller.

The Soundy germ. Two years later, in 1954, the so -called “Shrimp” bomb during the Castle Bravo test. A powerful explosion was expected, but the result of 15 megatons (1,000 times Hiroshima) even surprised its designers, both by strength and by the devastating level of radiation released. However, Teller’s impetus did not stop there either. I wanted more, Much more.

It was then that one of the most delusional and terrifying projects of nuclear history emerged: the Sundial Project. Designed by Teller and his colleagues from the Livermore Radiation Laboratory, the plan proposed a new destruction scale: no already kilotons or megatones, we entered In the gigatons.

A couple of brothers. They were designed Two weapons: Gnomon and Sindial. Gnomon would act as “primary”, with a detonation of 1,000 megatons aimed at detonating Soundy, which would reach a power of 10,000 megatons, that is, 10 gigatons. For placing it in perspective, he thinks again The image of the beginning.

Well, the figure exceeds 200 times the tsar bomb, and almost does not fit in the conceptual framework of the physics of conventional explosions.

The potential apocalypse. The logic behind Sindial overflows any traditional calculation. To such powers, the laws of escalation of destruction They lose any validity: The heat, pressure and energy released would be so monstrous that, a priori, they would open a hole in the atmosphere.

In fact, A report Del Bulletin of the Atomic Scientists pointed out that a pump like a sundial, detonated about 45 kilometers of altitude, could cause fires in an area of the size of France. The death toll would be unthinkable, not only because of the immediate explosion but by global radioactive sequels. Hiroshima, with 140,000 victims, would be a sigh against cataclysm that would represent Sindial.

It was not science fiction. Although it might seem like a laboratory fantasy, the Sundial Project It was not a joke or an eccentric occurrence. Declassified documents and historical analysis indicate that Livermore’s team worked seriously For years in the development of Gnomon, with concrete plans to test it in the Redwing operation of 1956.

That test was canceled, but the mere existence of the plan shows to what extent the fear, scientific ambition and deterrence had pushed the superpowers to border the abyss of the unacceptable.

Echoes of Sindial. Suindial never materialized, but his mere conception forced A critical reflection In American politics. The growing destructive power of these weapons overflowed not only military strategy, but also ethics, logistics and land physics itself.

While many ruled out their tactical utility for being impracticable (a pump of such dimensions was impossible to launch), its potential as an instrument of symbolic terror was enormous. As with The TSAR pumpits value was more political than operational: a floating threat that showed how far a nation could go if I wanted.

Monster in the shadows. Finally, the Soundal project is It was diluting between political restrictions, international treaties and practical sense (without serving as precedent). The Ratification of the treaty Partial prohibition of nuclear trials in 1963 was a brake on atmospheric tests, which in practice made it impossible to continue advancing in the development of extreme performance weapons.

The strategy then went on to favor smaller, portable and operational multiple eyelets, leaving behind the vision of total apocalypse that represented Sindial and its cousin Soviet sister.

Imagine the unimaginable. What’s doubt, today sundial is just a footer in the history of nuclear war, but his lesson should be indelible. It reminds us something that we should not forget now that everything looks like So belligerent: There is no technical limit to the destructive power that the human being can build if he wishes.

Sindial and every year of research around them were kept in a box Strong so that nobody reopens it. However, the issue does not seem so much if we can relive it, but why the hell we would like. While modern nuclear powers explore New forms of delivery (from submarine drones to hypersonic systems), the logic that gave rise to Sindial remains more latent than ever.

If you want, the threat is no longer only physical, but symbolic: that of a humanity capable of imagining its own annihilation at planetary scale.
