Brian Cox is a physicist and professor at the University of Manchester, England.
Human universe explores questions about our origins, our destiny, and our place in the universe.
This book explores science, human origins, our place in the universe. Some interesting facts:
According to Brian Cox there is about 400 billion stars in the Milky Way Galaxy and about 350 billion galaxies in the observable universe.
The Milky Way is about 100,000 light years across. A light-year is about 6 trillion miles/10 trillion kilometers.
According to Brian Cox there are billions of potentially habitable worlds in the Milky Way alone.
A neutron star can have a mass several times of the sun but are only 10 kilometers in diameter.
Another cool fact: Pulsars are spinning neutron stars. The pulsar named PSR 1257+12 rotates at 9650 rpm or once every 6 milliseconds.
The universe extends way beyond the visible horizon 46 billion light years away and it would be impossible to explore the entire universe.
The Voyager Golden Record was designed to provide information to other possible forms of life in the universe. It contains sounds recordings, images, and information about Earth. Electroplated onto the surface of the record is a pure sample of Uranium 238 which has a half-life of 4.468 billion years and is a way for a civilization to determine the age of the record.
The earliest system of writing was from the Sumerians about 5000 years ago. Writing was profoundly influential to human consciousness because it freed the acquisition of knowledge from the limits of human memory.
The book ended by reminding us to enjoy life while we can.
Overall he presented a balanced attitude on the nature and limits of science.
No major criticisms.
