Cosmic inflation solves these problems at a stroke. In its earliest instants, the universe expanded faster than light ( light’s speed limit only applies to things within the universe).

By observing tiny ripples in spacetime called "gravitational waves" that propagate away from colliding black holes, scientists could reveal hidden asymmetries in the universe.

Physicist Alan Guth, the father of cosmic inflation theory, describes emerging ideas about where our universe comes from, what else is out there, and what caused it to exist in the first place.

Inflation, in the context of the big bang theory, refers to the episode of exponential expansion of the very early universe indicated by particle physics' Grand Unified Theories (Extensive references ...
