spacetime was flattened like a prune placed in water

Categories: Comparisons

An example of an analogy used to explain a science concept:

"The key point is that during inflation opposite regions of the Universe were blasted apart, in a sense, 'faster than light'. …This awesome expansion also ensures that spacetime gets highly flattened, in much the same way that the wrinkly surface of a prune becomes a smooth, flat surface when the prune is placed in water and swells up."
