"We don’t actually have definitive proof that [inflation] is truly what happened... It is by no means a done and dusted theory."
Jo Dunkley is a distinguished British astrophysicist and Professor of Physics at Princeton University, working on major international projects including the Atacama Cosmology Telescope and Simons Observatory, which focus on measuring the cosmic microwave background (CMB)—the earliest observable light in the universe. Her contributions have been recognised with numerous accolades, such as the Maxwell Medal, the Rosalind Franklin Award, and the New Horizons Prize and has recently been elected a fellow of the Royal Society.
Dunkley's recent research works on uncovering evidence of "inflation" in our early universe. This research works to also help us understand the big 'tensions' in cosmology and improve our understanding of dark matter.
