Question

Quizplus · Accepted Answer

Gravity becomes separate from the other forces at the end of the Planck Era, about $10^{-43}$ seconds after the Big Bang. This era marks the earliest known period following the formation of the universe, during which the four fundamental forces (gravity, electromagnetism, the strong nuclear force, and the weak nuclear force) are thought to have been unified.
