  • The earliest light emitted in the universe, the cosmic microwave background, dates to about 380,000 years after cosmic birth. The most widely accepted explanation is that the universe went through a period of rapid expansion in the first slivers of a second after the big bang. The ghost field is weak enough that it can be ignored, except during the bounce, when the universe is very small and dense. Using the ghostly equations, computational tools that describe space-time under general relativity show that tiny fluctuations from the dying universe can indeed be carried over into the reborn cosmos.
