Question 30 • Physics in the Universe

Which shows the correct order of events after the big bang occurred?

Answer
A
quarks and electrons formed, electromagnetic and weak forces separated from the unified force, inflationary expansion occurred, strong force separated from the unified force, gravity separated from the unified force
B
electromagnetic and weak forces separated from the unified force, gravity separated from the unified force, strong force separated from the unified force, inflationary expansion occurred, quarks and electrons formed
C
gravity separated from the unified force, strong force separated from the unified force, inflationary expansion occurred, electromagnetic and weak forces separated from the unified force, quarks and electrons formed
D
strong force separated from the unified force, inflationary expansion occurred, quarks and electrons formed, electromagnetic and weak forces separated from the unified force, gravity separated from the unified force

Explanation

In the usual simplified timeline, gravity separated from the unified force first, followed by the strong force. Inflationary expansion then occurred, after which the electromagnetic and weak forces separated; quarks and electrons formed later as the universe cooled. This sequence matches choice C.
