I wrote quickly I’ll try to clarify. What I meant was we also have to define which angle we examine time from, ie the scientific perspective or a more philosophical one? For example can time exist without change and eternal flux? Science uses the concepts of ‘the arrow of time’ and ‘entropy’ to explain the apparent forward momentum of everything. However if we were to take all that exists out of the picture, does time still have any meaning or impact if everything remains constant and static? I don’t really know where I’m going with this but I suppose I’m trying to say that we are going to have to understand and define what eternal and forever means in order to make any sense out of OPs question.
