摘要：

In the very early Universe, gravity may briefly have become repulsive. The ensuing period of rapid expansion, called ‘inflation’, could account for such fundamental matters as the origin of galaxies and galaxy clusters. But if a new analysis of the cosmic microwave background stands up, inflation either cannot be so simple, or must be discarded.
