In a groundbreaking announcement, Professor Mark Thomson, the incoming Director-General of the European Organization for Nuclear Research (CERN), emphasized the transformative role of artificial intelligence (AI) in particle physics. Starting his tenure on January 1, 2026, Thomson envisions AI as a revolutionary tool capable of not just enhancing scientific research but potentially revealing the fate of the universe itself.
At the heart of this revolution lies the Higgs boson, often dubbed the “God particle”, which was first discovered in 2012. The Large Hadron Collider (LHC), CERN’s flagship particle accelerator, has been instrumental in this discovery. Now, with the integration of advanced AI technologies, CERN aims to achieve what once seemed impossible—observing the simultaneous formation of two Higgs bosons and uncovering deeper mysteries of the cosmos.
The Role of the Higgs Boson in the Universe
To understand the significance of AI in particle physics, it’s essential to revisit the importance of the Higgs boson:
- What is the Higgs boson?
Discovered in 2012, the Higgs boson is a fundamental particle responsible for giving mass to other particles. It’s a key component of the Standard Model of particle physics, which explains how particles interact through fundamental forces. - Why is it called the “God particle”?
The nickname reflects its critical role in the universe’s structure, as it helps explain why matter exists in the form it does. Without the Higgs boson, particles would lack mass, and the universe as we know it wouldn’t exist.
Now, researchers aim to go a step further by observing two Higgs bosons forming simultaneously, an event so rare that it has eluded detection until now.

AI’s Game-Changing Impact on Higgs Boson Research
1. Observing the Rare Formation of Two Higgs Bosons
According to Professor Thomson:
“There is a special measurement of the Higgs boson that is so fundamental to the nature of the universe. What we will be looking at is the formation of not one Higgs boson, but two Higgs bosons at the same time.”
This breakthrough is made possible by AI’s ability to:
- Analyze massive datasets from LHC experiments
- Detect patterns and anomalies that humans might miss
- Simulate complex particle interactions with unprecedented precision
Even five years ago, Thomson admits he would have considered this task beyond the LHC’s capabilities. Today, thanks to AI, it’s within reach.
2. Managing 40 Million Collisions Per Second
The LHC generates around 40 million proton collisions every second, creating an overwhelming amount of data. Dr. Catherine Leni, a physicist working on the ATLAS experiment at CERN, highlights AI’s critical role:
“When the LHC collides with protons, we have to make decisions within a microsecond—determining which events are interesting and worth keeping, and which ones to discard.”
AI helps by:
- Filtering data in real-time
- Identifying rare particle interactions
- Reducing the time needed to analyze experimental results
According to Leni, AI has advanced research by at least 20 years, accelerating discoveries that would have taken decades using traditional methods.

AI’s Broader Impact on Particle Physics and the Universe
1. Predicting the Fate of the Universe
Thomson suggests that AI’s analytical power could help answer one of humanity’s most profound questions:
How will the universe end?
By studying the behavior of the Higgs boson and other fundamental particles, AI can:
- Simulate the universe’s evolution over billions of years
- Predict potential scenarios for its ultimate fate, such as the Big Freeze, Big Rip, or Big Crunch
2. Searching for Dark Matter
Dark matter, an invisible substance believed to make up about 27% of the universe, has long eluded direct detection. Scientists hope the LHC might produce dark matter particles, but the challenge is immense due to their:
- Lack of interaction with light
- Rarity in high-energy collisions
Thomson believes that generative AI can help:
- Identify subtle signatures of dark matter
- Explore new theoretical models
- Optimize experimental setups for better detection

Future Prospects: The High-Luminosity LHC and Beyond
1. Major LHC Upgrade by 2030
CERN is preparing for a major upgrade of the LHC, known as the High-Luminosity LHC (HL-LHC), which will:
- Increase beam intensity by a factor of 10
- Enable the study of rarer particle interactions
- Generate even larger datasets for AI analysis
This upgrade is expected to unlock groundbreaking discoveries in the next decade.
2. The Role of Generative AI in Theoretical Physics
Beyond data analysis, AI is now being used to:
- Generate new hypotheses in theoretical physics
- Predict outcomes of experiments before they’re conducted
- Simulate particle interactions at scales beyond current experimental limits
Challenges and Skepticism in the Scientific Community
While AI’s potential is immense, some scientists remain skeptical:
- Lack of “grand results” since 2012: Despite the Higgs boson discovery, the LHC hasn’t produced similarly revolutionary findings in recent years.
- Reliance on AI: Concerns exist about over-reliance on AI, potentially overlooking human intuition and creativity in scientific discovery.
- Interpretability issues: AI models, especially deep learning systems, can sometimes act as “black boxes,” making it difficult to understand how they reach conclusions.
Nevertheless, most experts agree that AI is an indispensable tool for the future of physics.
