The formation of protons over neutrons (thus producing about a 7:1 ratio) was favored in the early universe because:____.
tatiyna

Because it requires more energy to create a neutron from a proton than it does to create a proton from a neutron, protons were formed more frequently than neutrons in the early universe. The correct answer is option b.

To find the answer, we need to know more about the early universe.

<h3>How the formation of proton over neutrons was favored in the early universe?</h3>
  • A neutron is produced with greater energy than a proton.
  • However, later on, some of the protons were changed into neutrons.
  • Contrary to some claims, the proton is a stable particle that never decays, but the neutron is unstable outside of the nucleus and decays with a half life of around 10.5 minutes.
  • However, very few would have had time to decay on the timeline you mention in your question.
  • Every matter particle should have been accompanied by an antimatter particle, and every proton, neutron, and electron, by an anti-neutron and a positron, respectively.
  • Where did all the antimatter go is the great mystery. There have been a few attempts to explain this, but they have failed.

Thus, we can conclude that, the correct answer is option b.
