Does CERN create black holes? | Angels & Demons (2024)

The creation of black holes at the Large Hadron Collider is very unlikely. However, some theories suggest that the formation of tiny 'quantum' black holes may be possible. The observation of such an event would be thrilling in terms of our understanding of the Universe; it would also be perfectly safe.

Two types of black hole

Black holes form in space when certain stars, much larger than our Sun, collapse on themselves at the end of their lives. They concentrate a very large amount of matter in a very small space. They are so dense that the gravity they exert is such that not even light can travel out of them.

Speculations about black holes at the LHC refer to particles produced in the collisions of pairs of protons. These are microscopic - or quantum - black holes. Scientists are not at all sure that quantum black holes exist.

The physical part of the LHC experiments - colliding particles - happens in nature all the time. We know, for example, that the Earth is constantly bombarded by cosmic rays: when cosmic rays hit the atmosphere, particles are colliding with one another in much the same way as in the collisions planned at the LHC.

Just as we know that the Earth is safe under the natural bombardment from cosmic rays, so we know that recreating these collisions poses no threat to the Earth. Nature’s collisions also reach much higher energies than those at the LHC.

What if collisions at the LHC produced a black hole?

The creation of a quantum black hole at the LHC would be very surprising, but very exciting indeed. It would allow physicists to learn about nature’s most elusive force – gravity.

Remember: particle collisions happen all the time in nature, and we're all still here. If you would like to read up more on the safety of the LHC, there is more information here.

What would be the significance of the creation of a black hole at the LHC?

The creation of a black hole at the LHC would confirm theories that our universe is not 4 dimensional (3 space plus 1 time dimensions), but indeed hosts other dimensions. It would be quite a spectacular philosophical outcome! In the same way that the theory of relativity or of quantum mechanics revolutionized our way of thinking, discovering the existence of extra dimensions would be a major new milestone in our understanding of the Universe.

There is no obvious application for knowing this. Many people will start speculating about using these extra dimensions for space and time travel, or as a source of clean energy, and who knows what else. It is rather tempting to compare it to the discovery of magnetism by the Phoenicians who could not foresee that electricity and magnetism would completely reshape modern life...

FAQs

Is CERN trying to create a wormhole? ›

Does the Large Hadron Collider create black holes or wormholes that could be used as portals? No. Absolutely not.

Can the Hadron Collider create dark matter? ›

Experiments at the Large Hadron Collider (LHC) may provide more direct clues about dark matter. Many theories say the dark matter particles would be light enough to be produced at the LHC. If they were created at the LHC, they would escape through the detectors unnoticed.

What is CERN trying to do? ›

We want to advance the boundaries of human knowledge by delving into the smallest building blocks of our universe.

Can black holes be created? ›

In fact, the possibility of creating a black hole in a lab is a goal that scientists are actively pursuing—one that could allow researchers to answer many fundamental questions about quantum mechanics and the nature of gravity. A black hole typically forms when a star much more massive than our sun dies.

What is CERN trying to do with dark matter? ›

It is hoped that CERN's planned new "Future Circular Collider" will be able to discover what makes up dark matter. Scientists at the European Organisation for Nuclear Research (CERN) say they are planning to build a new world's biggest particle collider.

Who controls CERN? ›

CERN is run by 23 Member States, each of which has two official delegates to the CERN Council. The CERN Council is the highest authority of the Organization and has responsibility for all-important decisions. It controls CERN's activities in scientific, technical and administrative matters.

What is the dark energy theory? ›

Overview: Dark energy is an as-yet unexplained force that appears to be accelerating the expansion the Universe. Its unexpected and counterintuitive discovery in the late 1990s was initially met with skepticism, but further studies have independently confirmed the initial results.

What is the hidden valley theory? ›

“In Hidden Valley models we have two groups of particles separated by an energy barrier. The theory is that there could then be exotic massive particles which could cross this barrier under specific circ*mstances.

Does the Hadron collider affect humans? ›

No. Although powerful for an accelerator, the energy reached in the Large Hadron Collider (LHC) is modest by nature's standards. Cosmic rays – particles produced by events in outer space – collide with particles in the Earth's atmosphere at much greater energies than those of the LHC.

What did CERN do to the world? ›

Since CERN began in 1954, we have made many significant breakthroughs, both in particle physics (such as our early discovery of neutral currents) and technologies that have helped improve our day-to-day lives (including the World Wide Web).

What is God particle in simple words? ›

In the standard model of Particle Physics, the Higgs Boson (also known as God particle), is the elementary particle that decays quickly, it is very unstable, has no electric charge and has zero spins. It is found in the Higgs field.

Why does CERN have a Shiva statue? ›

Why does CERN have a statue of Shiva? The Shiva statue was a gift from India to celebrate its association with CERN, which started in the 1960's and remains strong today. In the Hindu religion, Lord Shiva practiced Nataraj dance which symbolises Shakti, or life force.

Where do black holes take you? ›

When matter falls into or comes closer than the event horizon of a black hole, it becomes isolated from the rest of space-time. It can never leave that region. For all practical purposes the matter has disappeared from the universe.

Are we already in a black hole? ›

Earth is not just tucked into a planet-size black hole or even one the size of the solar system. If that were the case, scientists would have noticed, Field told Live Science. There would be observable signatures of the black hole's spinning.

What did Stephen Hawking believe about black holes? ›

Hawking eventually squared the two ideas in 1974, showing that black holes could have entropy and emit radiation over very long timescales if their quantum effects were taken into account. This phenomenon was dubbed "Hawking radiation" and remains one of the most fundamental revelations about black holes.

Can the Hadron collider create a wormhole? ›

Prior to the opening of the Large Hadron Collider (the LHC) back in 2008, theoretical physicists at the Steklov Mathematical Institute, Moscow, conjectured as to the possibility that the LHC could generate sufficient energy to rip spacetime, creating subatomic worm holes. But as of today, that has not happened.

Did scientists really create a wormhole? ›

Wormholes emerge as possible solutions to Einstein's theory of general relativity and could hypothetically cut the distance between otherwise distant regions of spacetime. The math checks out, but so far we have yet to see a wormhole either in the lab or existing in nature.

Have we created a wormhole? ›

Einstein's theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date.

What will CERN discover? ›

Other new experiments at CERN probing the nature of the universe will focus on collisions of high-energy ions, to better understand the plasma that was present only in the first microsecond after the Big Bang; probe the insides of protons; study cosmic rays; and search for the still-hypothetical magnetic monopole, an ...
