# Curiosity (TV series)

Curiosity is an American documentary television series that premiered on August 7, 2011, on the Discovery Channel. Each episode focuses on one question in science, technology, and society (e.g., why the RMS Titanic sank) and, for the first season, features a different celebrity host. Stephen Hawking hosted the premiere episode titled "Did God Create the Universe?", which aired simultaneously on seven Discovery Communications networks: Discovery Channel, TLC, Discovery Fit and Health, Animal Planet, Science, Investigation Discovery, and Destination America. Season one consists of 16 episodes.

## Curiosity: The Questions of Our Life

The development of "Curiosity: The Questions of Our Life", was announced in September 2009. It was to answer questions and mysteries in fields like space, biology, geology, medicine, physics, technology, nature, archaeology, history, and the human mind. It was considered as a groundbreaking series for Discovery like the BBC's Planet Earth and Life. Originally, this series was to be a monthly show airing 12 one-hour episodes each year for 5 years beginning in January 2011. Dan Riskin was initially slated to host.

## Curiosity.com

The website was opened in June 2011. It was to be an expert Q&A site, where experts and scholars tried to answer some of life's most profound questions. The 32 topics in site ranges from biodiversity to nanotechnology. So far 12,000 questions have been answered. On November 11, 2014, Curiosity.com became independent of Discovery Communications.

| Stephen Hawking says that his 2010 book The Grand Design upset some people. He says that it is valid for him to ask whether one creator god single-handedly created the living and non-living things. He wants to know "what or who created and controls the universe." In the ancient times, even the Vikings believed that "gods made everything." The narrator [Benedict Cumberbatch] states that multiple gods controlled different phenomena for the Vikings. He cites the example that Ægir "caused stormy seas." According to the narrator, Sköll was a "wolf god" who caused solar eclipses. In ancient Greece, Aristarchus of Samos was fascinated by eclipses. Aristarchus wanted to know if solar and lunar eclipses were caused by the Greek gods. A few months before his death in 1277, Pope John XXI declared the laws of nature a heresy. In 1600s, Galileo Galilei found that "some object do not orbit the Earth." Galileo had discovered the four moons of Jupiter. Hawking believed in his childhood that "you never get something for nothing", but now he thinks "you can get a whole universe for free!" Cumberbatch narrates that space is a "vast store of negative energy." |||||
