WIFI Model Suggests Dark Matter Originated Pre-Big Bang

Nov 30, 2024, 05:02 PM

Researchers have proposed a new cosmological model suggesting that dark matter may have been produced during the inflationary phase before the Big Bang. This phase, known as pre-Big Bang inflation, was a period of rapid cosmic expansion. The model, named Warm Inflation via Ultraviolet Freeze-In (WIFI), theorizes that dark matter formed through rare processes during this time. This hypothesis challenges existing theories of dark matter's origin and awaits validation through future cosmic microwave background experiments.
