Historic Higgs boson discovery - it "could" exist
- Published
Scientists around the world have discovered the results from one of the biggest experiments in history.
They were hoping to prove the existence of a particle called the Higgs boson - and they have - pretty much!
They say a sub-atomic particle has been discovered which is "consistent" with what the Higgs boson would be like.
But they still have to say it "could" be the Higgs boson - because they can't be absolutely 100% certain.
Physicists worked for months in an underground laboratory in Europe, smashing particles together inside a 16-mile tube called the Large Hadron Collider (LHC).
They're convinced the Higgs boson particle is the evidence for how the universe works.
What is the Higgs boson?
A top scientist Professor Peter Higgs predicted in the 1960s that there is a particle out there which could explain the workings of the universe.
If its existence could be confirmed, it would prove that all particles have mass - that's a measure of how much 'stuff' an object - such as a particle or molecule - contains.
Particle expert Tara Shears from Liverpool University says: "If particles didn't have mass, you wouldn't have stars, you wouldn't have galaxies, you wouldn't even have atoms. The Universe would be entirely different."
Protons are fired through a huge ring 16 miles in circumference
It contains 9,300 magnets cooled to -271.3 degrees C
It's officially the world's largest fridge
The protons go round the collider 11,245 times every second
Professor Jeff Forshaw of Manchester University describes the Higgs boson as being like dragging a ball through treacle!
'Boson' is another word for 'particle' and is named after the Indian scientist S N Bose who researched particles in the 1940s.
