A. Three minutes after the Big Bang
B. One second after the Big Bang
C. 500,000 years ago
D. 1 million years after the Big Bang
E. 500,000 years after the Big Bang

Answer :

Final answer:

All forces in nature are theorized to appear one second after the Big Bang, along with particles such as neutrons, protons, and electrons.


Explanation:

In the early moments of the Universe, about one second after the Big Bang, all the forces in nature are theorized to have appeared along with particles such as neutrons, protons, and electrons. At this time, the Universe was extremely hot and dense, with temperatures exceeding billions of degrees.


During this period, three out of the four fundamental forces - electromagnetic force, strong nuclear force, and weak nuclear force - were already unified into a single force, known as the electroweak force. The gravitational force remains separate.


As the Universe continued to expand and cool, about 380,000 years after the Big Bang, particles combined to form neutral atoms, and photons were able to travel freely. This milestone is known as recombination, marking the point when the Universe became transparent to light.
