The question is, does causality require time? I understand that physics can give us a definition of time as far as "happens-before" relationships go, but are "happens-before" and "happens-because-of" necessarily the same thing?
- sdegutis 8y agoIf the world has begun with a single quantum, the notions of space and time would altogether fail to have any meaning at the beginning; they would only begin to have a sensible meaning when the original quantum had been divided into a sufficient number of quanta. If this suggestion is correct, the beginning of the world happened a little before the beginning of space and time. Lemaître, G. (1931).
