Recentering the Universe: The Radical Theories of Copernicus, Kepler, Galileo, and Newton

Take a look inside

For more than a 1,000 years, the Earth was at the centre of the universe, according to established scientific thinking and teachings of the Catholic Church. Defiance of Church doctrine could mean death, so no one dared dispute this long-accepted idea. In the 1500s & 1600s, men like Nicolaus Copernicus, Johanned Kepler, Galileo Glilei, and Isaac Newton began to ask questions. What if Earth actually orbited the sun, instead of the other way around? What if the universe was much bigger than anyone imagined? These scientists risked their reputations-even their lives-to challenge the very heart of Catholic dogma and scientific tradition. Yet, in less than 200 years, their radical thinking overturned theories that had lasted more than a millennium.
