In What Way Does the Study of the Collisions of Very

question 177

Multiple Choice

In what way does the study of the collisions of very high-speed nuclear particles with other matter at particle accelerator laboratories help in the understanding of the early universe?

• A) The temperature of the early universe was so high that mutual collisions of particles occurred at energies equivalent to those in nuclear particle accelerators.
• B) Nuclear accelerators generate enormous quantities of microwaves similar to those that existed in the early universe, thus allowing the study of the interaction of microwaves with matter.
• C) Motions of particles in circular orbits around the original black hole produced by the Big Bang were similar to the particle motions in an accelerator.
• D) Collisions in nuclear accelerator laboratories produce large numbers of neutrinos and hence mimic the conditions that were thought to exist in the early universe, where neutrinos occupied most of the space.
