Standard Model Tames the 'Particle Zoo' of Subatomic Physics
Imagine the universe is made of tiny LEGO bricks.
For a while, scientists kept discovering new types of bricks, called particles, and it got confusing.
Then, they built a 'Standard Model' to sort them into groups like quarks, leptons, and bosons.
Quarks and leptons are like the LEGO bricks themselves.
Bosons are like the glue or messages that hold the bricks together, or give them mass.
This model explains a lot, like how atoms stay together, but it doesn't explain everything, like gravity or dark matter.
Scientists are still working to understand the full picture of the universe's building blocks.
The Standard Model is a theoretical framework classifying all known elementary particles.
It describes three fundamental forces: electromagnetic, weak, and strong interactions.
The model sorts particles into quarks, leptons, and bosons.
The Higgs boson gives mass to other particles.
The Standard Model does not include gravity, dark matter, or dark energy.
