    They predicted that the Universe were created in a Big Bang. Today, we would see the glow of light that was released when atoms first formed when the universe was about 300,000 years old. Since the universe has been expanding for billions of years, the light would have been redshifted by a factor of 1,000 so that it could only be detected today as microwaves. In 1964, Arno Penzias, and Robert Wilson of Bell Labs announced they had identified this light providing the strongest evidence to date in support of the Big Bang theory.
