Can a Planet Orbit Two Stars?
Two stars can circle each other while a planet travels around them both. Astronomers confirmed it by watching the moving stars dim.

What Is the Higgs Field, and Why Call Its Particle the “God Particle”?
An everywhere-present field, a fleeting particle and a famous nickname. What did CERN’s experiments actually measure?
THE SHORT ANSWER
The Higgs field is a quantum field present throughout space. Its interactions give particles such as electrons and quarks their rest masses. The Higgs boson is an excitation of that field, discovered at CERN in 2012. “God particle” is a popular nickname from a book about the search. Understanding the discovery means separating the field, its particle and the signals recorded by detectors.
- The Higgs field and a Higgs boson have different roles.
- Decay products allowed researchers to infer a short-lived new particle.
- Most proton mass comes from strong-interaction energy.
- The God particle nickname comes from a popular-science book.
About this picture
Original AI-generated conceptual illustration for God Plays Dice. The continuous lines suggest a field and the bright feature suggests an excitation. Colors and geometry are artistic choices; this is an illustration rather than a detector image or a measured view of the Higgs field.
WHERE THE EVIDENCE STANDS
How sure are we?
- A Higgs boson is an excitation of the Higgs field.CERN distinguishes the particle from the background field.
- ATLAS and CMS discovered a new particle in 2012 whose later measurements match the Higgs interpretation.The discovery used decay products and statistical comparisons with backgrounds.
- The Higgs field accounts for all the mass of protons.Strong-interaction energy provides most proton mass.
- Are there additional kinds of Higgs boson?ATLAS describes searches for additional Higgs particles beyond the Standard Model.
WHAT WE DON’T KNOW YET
The Higgs boson’s properties are still being measured more precisely. Whether additional Higgs particles exist and how the Higgs fits into a deeper theory remain open.
WHAT WOULD CHANGE THIS ANSWER
Independently confirmed deviations in Higgs production, decay or interactions, or the discovery of additional Higgs particles, would change this account.
The Higgs field can be present even when a collider is producing no Higgs bosons. How can a field fill space while its particle is so difficult to find? Start with the difference between a field’s background state and an excitation of it.
