Each time period corresponds with an event in the list below labeled a to e.

Starting with the earliest time period (10^−34 s), list which time period corresponds to which
event.

For example if you think the times at 10^−34 s, 10^−12 s, 10^−10 s, 3 min, and 380, 000 years
respectively correspond to events a, b, c, d, and e, then input “a b c d e”

a) Cosmic Microwave Background forms
b) Higgs gets “frozen” into the Universe
c) Inflation rapidly expands the size of the Universe
d) Nucleosynthesis of light elements such as 4He
e) WIMPs—a possible dark matter candidate—fall out of thermal equilibrium.

To determine which time period corresponds to which event, we need to examine the descriptions of each event and match them with the appropriate time period. Let's break down each event and analyze the information given:

a) Cosmic Microwave Background forms: The Cosmic Microwave Background (CMB) is the electromagnetic radiation left over from the early stages of the universe. It is believed to have formed around 380,000 years after the Big Bang.

b) Higgs gets "frozen" into the Universe: The Higgs boson is a particle associated with the Higgs Field, which gives other particles mass. "Freezing" of the Higgs into the universe refers to the moment when it acquires its non-zero vacuum expectation value. This event occurs during the electroweak symmetry breaking, which happened approximately 10^−12 seconds after the Big Bang.

c) Inflation rapidly expands the size of the Universe: Inflation is a theoretical period of extremely rapid expansion that occurred in the early universe. It is believed to have taken place around 10^-34 seconds after the Big Bang.

d) Nucleosynthesis of light elements such as 4He: Nucleosynthesis is the process of forming atomic nuclei through nuclear reactions. Light elements like helium are believed to have been synthesized during the early stages of the universe, specifically during the first few minutes after the Big Bang.

e) WIMPs - a possible dark matter candidate - fall out of thermal equilibrium: WIMPs (Weakly Interacting Massive Particles) are hypothetical particles that could potentially constitute dark matter. Falling out of thermal equilibrium refers to the moment when their interactions with other particles become less frequent. This event is believed to have occurred at around 10^-10 seconds after the Big Bang.

Now that we have analyzed each event and its corresponding time frame, we can match them up:

The correct answer should be:
a) 3 min
b) 10^−12 s
c) 10^−34 s
d) 3 min
e) 10^-10 s

Therefore, the correct input would be: c b e d a.
