Question

Quizplus · Accepted Answer

The critical universe proposed by current scientific theories, including the most widely accepted Lambda-CDM model, suggests that the universe contains about 27% matter (including dark matter) and 73% dark energy. Therefore, the ratio of matter to energy in this critical universe is approximately 27:73. The critical universe theory proposes that the total mass-energy density of the universe is equal to the critical density necessary for the universe to be flat. This critical density is estimated to be about 5 atoms (of hydrogen) per cubic meter. Observations have shown that the ratio of matter (baryonic matter and dark matter) to energy (radiation and dark energy) is approximately 27:73. Therefore, the best choice is B.
