D)the positively charged protons were repelled away from the explosion.

Question

Quizplus · Accepted Answer

In the early universe, it takes more energy to create a neutron from a proton than a proton from a neutron due to the mass difference and the weak force interactions involved, leading to a higher abundance of protons.
