• B) The amount of matter (both visible and dark) is only 1/3 the amount needed to halt expansion, and there is strong evidence of a previously unknown form of energy that acts to accelerate the expansion.
• C) The amount of matter (both visible and dark) is exactly the right amount needed to halt expansion after an infinite amount of time has gone by.
