Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the epoch duration?Approximately 10^-36 to 10^-12 seconds post-Big Bang
2. What is the energy scale?Roughly 100 GeV, corresponding to temperatures around 10^15 Kelvin
3. What was the electroweak epoch and when did it happen?It was a brief period right after the Big Bang, from about 10^-36 to 10^-12 seconds, when electricity and magnetism were one force.
4. How were electricity and magnetism the same force?At very high energies around 100 GeV, the electromagnetic and weak nuclear forces merged into a single electroweak force that acted on particles like quarks and leptons.

Electroweak Symmetry Breaking: The process by which the unified electroweak force splits into distinct electromagnetic and weak forces as the universe cools.
Higgs Mechanism: A theoretical framework explaining how elementary particles acquire mass through interaction with the Higgs field.
Baryogenesis: The hypothetical process that produced the imbalance between matter and antimatter in the early universe.
Grand Unified Theories (GUTs): Theoretical frameworks that propose the unification of the strong nuclear force with the electroweak force at extremely high energies.
