Packet 5: Bonus 10
Answer the following about dark energy. For 10 points each:
[10e] Dark energy makes up 68% of the total mass-energy of this entity. It is thought to be the reason why the expansion of this entity, which is quantified by the Hubble constant, is accelerating.
ANSWER: the universe
[10m] Dark energy is thought to be quantified by this constant, symbolized lambda, which Albert Einstein called his “biggest blunder.” This constant and cold dark matter name the most commonly accepted model of the universe.
ANSWER: cosmological constant (The second sentence refers to the lambda-CDM model.)
[10h] The accelerating expansion is hypothesized to eventually cause galaxies beyond the Local Group to recede beyond the “cosmological” type of this structure. The holographic principle suggests that information is encoded on this structure, rather than destroyed when an object crosses one of these boundaries.
ANSWER: event horizon [accept cosmological (event) horizon or particle horizon]
