Robert Woodrow Wilson

description Robert Woodrow Wilson Overview

Robert Woodrow Wilson was an American physicist renowned for his pioneering work in cosmology. He developed innovative experimental techniques to study the cosmic microwave background (CMB) radiation, a crucial remnant of the Big Bang. His research significantly advanced our understanding of the early universe and earned him the 1978 Nobel Prize in Physics. Wilson's contributions are particularly relevant to astronomers, cosmologists, and researchers investigating the origins and evolution of the cosmos.

help Robert Woodrow Wilson FAQ

What did Robert Woodrow Wilson discover and with whom?

Robert Woodrow Wilson, together with his Bell Labs colleague Arno Penzias, discovered the cosmic microwave background radiation in 1964 using the Holmdel Horn Antenna in New Jersey. Their discovery provided the first strong observational evidence for the Big Bang theory.

Who shared the 1978 Nobel Prize in Physics with Robert Woodrow Wilson?

Wilson shared the 1978 Nobel Prize in Physics with Arno Penzias for the CMB discovery, and the prize was also awarded to Pyotr Kapitsa separately for his work in low-temperature physics. Wilson and Penzias each received one quarter of the prize.

What instrument did Robert Woodrow Wilson use to discover the cosmic microwave background?

Wilson and Penzias used the Bell Labs Holmberg Horn Antenna, a 20-foot horn-reflector antenna originally built for satellite communication experiments. The persistent background noise they detected corresponded to a temperature of approximately 3 kelvin.

Were Wilson and Penzias aware of the Big Bang theory's prediction when they found the CMB?

Initially no — Wilson and Penzias were trying to eliminate what they thought was instrument noise, even cleaning pigeon droppings from the antenna. They only connected their signal to cosmology after learning of Ralph Alpher and Robert Herman's earlier predictions and discussions with Robert Dicke's group at Princeton.
