 According to the B-theory (tenseless theory, block universe view), (a) all times and/or events exist and are equally real (this is known as eternalism—not to be confused with divine timelessness which has also sometimes gone by the same name); and (b) there is a complete tenseless description of temporal reality. A tenseless description is one that stays accurate, because it mentions only such things as which events happen when, and how they are temporally related to one another. So it mentions only facts about B-relations like simultaneity and succession. Call these tenseless facts. The B-theory combines eternalism with the claim that there is a complete description of temporal reality, a description of temporal reality at its most fundamental, that doesn’t mention any tensed facts, like that it’s 12:00 now.
