Multiple Choice
In the present universe there is an imbalance between particles and antiparticles. How did this originate?
A) It is believed that there are slight differences in mass between matter and antimatter. Thus the inflationary epoch, which gave mass and energy to the universe, created an imbalance of particles.
B) It is believed that there are slight differences in electric charge between matter and antimatter. Thus the inflationary epoch, which gave mass and energy to the universe, created an imbalance of particles.
C) We see only a small part of the universe. The missing antimatter is elsewhere, repelled by the negative mass of normal matter early in the history of the universe.
D) This question is an unsolved mystery of present-day cosmology.
