The Electromagnetic and Weak Nuclear Forces Are Predicted to Have

question 87

Multiple Choice

The electromagnetic and weak nuclear forces are predicted to have been indistinguishable at some stage in the early universe. What conditions were required at this stage?

• A) extremely high temperatures, producing very energetic collisions between components of matter
• B) very low density of matter, such that the weak force became as strong as the electromagnetic force in this region of space
• C) very high density of matter, such as the interior of the nucleus of an atom or a neutron star, where particles are so close that weak forces become equivalent to electromagnetic forces
• D) extremely low temperatures, where collisions of particles were of low energy and extremely infrequent, such that electromagnetic and weak forces were equivalent
