"Nobel Prize-Winning Physicist Arno A. Penzias Dies at 90, Confirmed Big Bang Theory"

Arno A. Penzias, the Nobel Prize-winning physicist who, along with Robert W. Wilson, confirmed the Big Bang theory with the discovery of cosmic microwave background radiation in 1964, has died at the age of 90. His groundbreaking work settled the debate over the origin and evolution of the universe, marking a transition in cosmology and opening a new era of observational cosmology.
