"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. Penzias, a Holocaust survivor, made significant contributions to the field of astronomy and leaves behind a lasting legacy in the scientific community.

Einstein's theory of gravity confirmed by cosmic growth mapping.

Researchers from the Atacama Cosmology Telescope (ACT) collaboration have created a groundbreaking new image that reveals the most detailed map of dark matter distributed across a quarter of the entire sky, extending deep into the cosmos. The new map confirms Einstein's theory of how massive structures grow and bend light, over the entire 14-billion-year life span of the universe. The team tracks how the gravitational pull of large, heavy structures including dark matter warps the cosmic microwave background radiation (CMB) on its 14-billion-year journey to us, like how a magnifying glass bends light as it passes through its lens.
