user: Give me a summary about Michael Jackson

assistant: Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American singer, songwriter, dancer, and philanthropist. Dubbed the "King of Pop", he is regarded as one of the most significant cultural figures of the 20th century. Over a four-decade career, his contributions to music, dance, and fashion, along with his publicized personal life, made him a global figure in popular culture. Jackson influenced artists across many music genres; through stage and video performances, he popularized complicated dance moves such as the moonwalk, to which he gave the name, as well as the robot.

The eighth child of the Jackson family, Jackson made his public debut in 1964 with his older brothers Jackie, Tito, Jermaine, and Marlon as a member of the Jackson 5 (later known as the Jacksons). Jackson began his solo career in 1971 while at Motown Records. He became a solo star with his 1979 album Off the Wall. His music videos, including those for "Beat It", "Billie Jean", and "Thriller" from his 1982 album Thriller, are credited with breaking racial barriers and transforming the medium into an artform and promotional tool. He helped propel the success of MTV and continued to innovate with videos for the albums Bad (1987), Dangerous (1991), HIStory: Past, Present and Future, Book I (1995), and Invincible (2001). Thriller became the best-selling album of all time, while Bad was the first album to produce five US Billboard Hot 100 number-one singles.

user: Who are Torvill and Dean?

assistant: Torvill and Dean (Jayne Torvill and Christopher Dean) are English ice dancers and former British, European, Olympic, and World champions. At the Sarajevo 1984 Winter Olympics the pair won gold and became the highest-scoring figure skaters of all time for a single programme, receiving twelve perfect 6.0s and four 5.9s which included artistic impression scores of 6.0 from every judge, after skating to Maurice Ravel's Boléro. One of the most-watched television events ever in the United Kingdom, their 1984 Olympics performance was watched by a British television audience of more than 24 million people.The couple went on to record an even higher score at the 1984 World Championships, thirteen 6.0s and five 5.9s.

The pair turned professional following the 1984 World Championships, regaining amateur status briefly ten years later in 1994 to compete in the Olympics once again. The pair retired from competitive skating for good in 1998 when they toured one last time with their own show, Ice Adventures, before rejoining Stars on Ice for one more season. Their final routine was performed to Paul Simon's "Still Crazy After All These Years", a routine they had devised a few years earlier for competition. Although remaining close friends, the pair did not skate together again until they were enticed out of retirement to take part in ITV's Dancing on Ice. Their career was portrayed in the 2018 biographical film Torvill & Dean.

Both are from Nottingham, England, where the local National Ice Centre is accessed through a public area known as Bolero Square, in honour of the pair's Olympic achievements. There is also a housing estate in the Wollaton area of the city with a street named 'Torvill Drive' and another named 'Dean Close' which is located just off Torvill Drive, with many of the surrounding roads named after coaches and dances associated with the pair. In a UK poll conducted by Channel 4 in 2002, the British public voted Torvill and Dean's winning performance at the 1984 Winter Olympics as Number 8 in the list of the 100 Greatest Sporting Moments.

user: Why does the Earth revolve around the Sun?

assistant: The Earth revolves around the Sun due to gravity. The more mass an object has, the greater its gravitational pull on other objects. The most massive object in the solar system is the sun, which is actually one of the larger yellow dwarf stars in the universe. With a mass of 1.98892 x 10 to the 30th power kilograms, the sun has approximately 333,000 times more mass than Earth. Because the gravitational pull of the sun is so much more than the Earth's gravitational pull, the Earth is forced into an orbit around the sun.
