The Large Hadron Collider (LHC) poses no credible risk of destroying Earth by creating a microscopic black hole

Key insights

Across the quotes, the same safety conclusion is reached through different mechanisms: inability to create a dangerous black hole, immediate evaporation, cosmic-ray precedent, or weak gravity.
Official CERN sources and experiment collaborations appear alongside outside physicists, science communicators, fact-checkers, and general news outlets, and they largely use similar safety framing.
Many quotes answer black-hole fears together with claims about portals, wormholes, timelines, or damaged reality, showing that the risk debate is often bundled with broader conspiracy narratives.
Several sources explicitly distinguish hypothetical microscopic collider objects from the massive astrophysical black holes familiar from popular culture.
The more cautious quotes tend to frame danger only as an 'in principle' or highly speculative scenario, not as a credible present risk under LHC conditions.

Arguments for

Insufficient collision energy

Several quotes say current accelerators are nowhere near the energy needed to create a dangerous black hole, and some state that the LHC simply cannot make one from its proton collisions at all. In this view, the basic physical precondition for an Earth-threatening event is missing.

Current particle accelerators are nowhere near the energy scale needed to create a dangerous black hole.

The LHC gives a lot of energy to particles, but nowhere close to producing a black hole. The LHC simply can’t do that.

Dr. Alfredo Carpineti · Mar 12, 2026 · full quote
CERN's equipment began operating in March, a month before the eclipse, and the technology is nowhere near strong enough to open a portal or a black hole.

Gabrielle Settles · Apr 5, 2024 · full quote
At least in the energies we have with the LHC, the Large Hadron Collider, we cannot throw particles together with enough force to cause tiny black holes.

Delilah Gates · Jun 10, 2021 · full quote
So there's no possible way we're gonna make a black hole out of two protons at the Large Hadron Collider.

James Beacham · Oct 28, 2021 · full quote

Immediate evaporation

Another common argument is that even if speculative microscopic black holes were produced, they would be extremely tiny, unstable, and would disintegrate or evaporate almost immediately, often described as around 10^-27 seconds. Because they would vanish before accreting matter, these sources say they could not cause macroscopic harm.

According to Einstein’s theory of relativity, it is impossible for LHC to produce black holes. However, some speculative theories predict the production of microscopic black holes. All these theories predict that these particles would disintegrate immediately. Black holes, theref…

If micro black holes do appear they would disintegrate extremely rapidly, in around 10^{-27} seconds, as they decay into Standard Model or SUSY particles, producing many jets and leptons.

CMS Experiment · Jul 11, 2026 · full quote
These tiny black holes would emit all their energy - or "evaporate" - almost instantly through Hawking radiation, releasing a distinctive burst of particles that detectors like CMS at CERN could observe.

Quantum Black Holes are harmless for the environment: they will decay within less than 10⁻²⁷ seconds.

Any black holes that could be produced by the LHC would be microscopic, and they would immediately evaporate since they are no longer stable.

Ces collisions de protons au LHC font des particules excessivement légères, et donc elles créeraient un trou noir de la masse qu'elles ont, c'est-à-dire infiniment léger. Il ne pourrait pas attirer quoi que ce soit, il serait moins attractif qu'un caillou posé par terre, et il ne…

Natural-collision precedent

Many quotes argue that nature already produces similar or higher-energy collisions through cosmic rays striking Earth and the atmosphere. Since Earth and other astronomical objects have persisted through vast numbers of such events, these sources treat collider doomsday fears as inconsistent with what is already observed.

Physicists at the time published safety assessments addressing the concern directly, arguing that collisions of similar or greater energy already occur naturally and constantly from cosmic rays hitting the atmosphere.

El universo produce más de 10 millones de millones de experimentos similares a los del LHC por segundo. Si esas colisiones fueran peligrosas, esto contradeciría lo que observamos, ya que las estrellas, las galaxias y la Tierra continúan existiendo.

If this generated dangerous black holes, then the Earth has already been zapped by much higher-energy collisions from cosmic rays billions of times.

No, CERN says the upgraded collider is no more likely to destroy the universe than the original machine. Nature already performs millions of LHC-like particle collisions every second through cosmic rays striking Earth's atmosphere.

“These collisions are actually happening in nature all around us all the time. ... If they were creating black holes on these other natural collisions, then we could have expected to have seen some kind of impact from that.”

Gene Van Buren · Feb 9, 2026 · full quote

Negligible gravitational effects

A separate line of argument focuses on what a microscopic black hole would physically be like: very small in mass, weak in gravitational influence, and not an object that automatically 'sucks in' surrounding matter. On this view, even a formed object would not behave like the popular image of a planet-eating cosmic black hole.

Black holes don't suck in other matter. From far enough away, their gravitational effects are just like those of other objects of the same mass.

NASA Science · Mar 11, 2026 · full quote
If you took the Earth and could squash it down into a black hole, it would make a black hole the size of a tennis ball. You need a lot of material to get anything you could actually see and observe.

If you replaced the Sun with a black hole of the same mass, the solar system would get a lot colder, but the planets would stay in their orbits.

Middle ground

Speculative edge cases

A few quotes acknowledge that black-hole production can be discussed 'in principle' or under extra assumptions about dimensions, Hawking radiation, or other speculative conditions. But these remarks still describe the real-world LHC case as unlikely, impractical, or not something people should presently worry about.

“If reality has more than four dimensions, and if hawking radiation doesn't exist, and if CERN created a black hole with no charge ... then yes, CERN could create the black hole that would consume the world ... But it probably won't ever happen.”

Alex McColgan · Jan 15, 2026 · full quote
In principle, yes. In practice, no. That's what you need to do to ensure these things are safe.

Neil deGrasse Tyson · Mar 5, 2024 · full quote
CERN insists its research, including that of microscopic black holes, is perfectly safe, but some theorists believe it could cause a collapse of the entire universe.

HowStuffWorks · Mar 7, 2024 · full quote
Some worry it could destroy the world by creating mini black holes, strange matter, or even vacuum bubbles. But experts say there's no real risk of that, or at least, it's extremely unlikely.

Bright Side · Feb 10, 2026 · full quote
Si en algún momento somos capaces de generar un microagujero negro, el mundo no se destruirá, pero habrá que sentarse a tomar aliento.

Óscar del Barco Novillo · Feb 6, 2024 · full quote

In the provided quotes, the discussion is dominated by sources rejecting an Earth-destroying black-hole scenario at the LHC. They differ mainly in explanation: some say the collider lacks the necessary energy, while others emphasize rapid evaporation, natural cosmic-ray precedents, or the weak pull of microscopic objects. Only a small subset discusses highly conditional theoretical edge cases, and no direct sourced cluster in this sample argues that the risk is presently credible.
