About this ebook
Please note: This is a companion version & not the original book. Book Preview:
#1 The discovery of the cosmic microwave background radiation in 1965 was the first indication that the Universe had a beginning. It was also an indicator of how hot the Universe was in the beginning.
#2 Arno Penzias was one of the researchers who worked on the horn antenna at Crawford Hill. He had been born into a Jewish family in Munich, Germany, in 1933, the same year that the Nazis formed the Gestapo. He escaped to America in 1939, and went to Columbia University to study science.
#3 The shape of the horn antenna is designed to minimize interference from the ground and provide the best possible measurement of the strength of radio noise coming from different places in space. The strength of this radio noise is measured in terms of temperature, which is calibrated by the temperature of radiation emitted by a black body.
#4 The temperature of the Universe is thought to be zero K, but the antenna was actually 2 K hotter than it should have been. The engineers who built the horn antenna had previously measured the temperature of the antenna when pointed at the sky, which was 22. 2 K with an uncertainty of plus or minus 2. 2 K.

#5
The pair were still having problems with the antenna noise, and in December 1964 they met with a radio astronomer named Bernard Burke, who told them that a team at Princeton had found the radiation. They were not sure if they had found it or not, but they were relieved to be given a scientific explanation for their measurements.
#6
The first person to apply cosmological ideas to calculate how the other elements had formed was George Gamow, a Russian émigré physicist who worked at George Washington University in Washington, DC. He guessed that the Universe might have started out as a hot, dense gas of neutrons.
#7
The puzzle of the origin of the elements was one of the reasons why the Big Bang theory was developed. The basic idea was that the universe is expanding, but has not expanded out
