Fears that the Large Hadron Collider could create a world-ending black hole were mitigated by a simple astronomical observation: Earth is constantly bombarded by cosmic rays creating collisions with far greater energy than the LHC can produce. Since the planet has survived billions of years of these natural, high-energy events, the risk from the collider was deemed negligible.

Tech billionaire Bill Gates supports a radical concept called solar radiation management: releasing aerosols to reflect sunlight and cool the planet. This moves the idea of a "sun visor for Earth" from science fiction to a seriously considered, albeit controversial, last-resort solution for climate tipping points.
The massive energy consumption of AI has made tech giants the most powerful force advocating for new power sources. Their commercial pressure is finally overcoming decades of regulatory inertia around nuclear energy, driving rapid development and deployment of new reactor technologies to meet their insatiable demand.
Long before Einstein's relativity, scholars like Pierre-Simon Laplace and John Michell theorized about "dark stars." They reasoned that if a star were massive enough, its escape velocity could exceed the speed of light, trapping light and rendering it invisible. This early concept was based entirely on Newton's laws of gravity, demonstrating remarkable scientific foresight.
Regulating technology based on anticipating *potential* future harms, rather than known ones, is a dangerous path. This 'precautionary principle,' common in Europe, stifles breakthrough innovation. If applied historically, it would have blocked transformative technologies like the automobile or even nuclear power, which has a better safety record than oil.
The Standard Model of particle physics was known to be incomplete. Without the Higgs boson, calculations for certain particle interactions yielded nonsensical probabilities greater than one. This mathematical certainty of a flaw meant that exploring that energy range would inevitably reveal new physics, whether it was the Higgs or something else entirely.
The significant risk that coronal mass ejections (CMEs) pose to our electron-based infrastructure—shorting out grids, satellites, and computers—is a fundamental vulnerability. This existential threat could be a major long-term driver for the development and adoption of photon-based computing, which would be immune to such geomagnetic disturbances.
The singularity at a black hole's center is not a place in space but an inevitable moment in time for anything that crosses the event horizon. This conceptual flip means that trying to escape the singularity is as futile as trying to avoid next Tuesday. The flow of spacetime itself pulls everything inward toward a future point of infinite density.
AI will create negative consequences, like the internet spawned the dark web. However, its potential to solve major problems like disease and energy scarcity makes its development a net positive for society, justifying the risks that must be managed along the way.
Physicist Brian Cox's most-cited paper explored what physics would look like without the Higgs boson. The subsequent discovery of the Higgs proved the paper's premise wrong, yet it remains highly cited for the novel detection techniques it developed. This illustrates that the value of scientific work often lies in its methodology and exploratory rigor, not just its ultimate conclusion.
An anonymous CEO of a leading AI company told Stuart Russell that a massive disaster is the *best* possible outcome. They believe it is the only event shocking enough to force governments to finally implement meaningful safety regulations, which they currently refuse to do despite private warnings.
