There is no such thing as a four dimensional "spacetime". That is a abstract math only concept, nothing to do with reality. Time is not a thing, nor is it a dimension. Reality is not curved or flat. That is abstract geometry that they are talking about, not reality. Only 3 abstract dimensions are required to locate anything in reality. Time is just when you want to examine these three dimensions.
