LONDON (AP) — A wheelchair used by physicist Stephen Hawking has sold at auction for almost 300,000 pounds ($393,000), while a copy of his doctoral thesis fetched almost 585,000 pounds ($767,000), auctioneer Christie's said Thursday.

Days after legendary physicist Stephen Hawking's final paper was published, a great number of his prized possessions will go up for auction, including some of his most important papers, including his doctoral thesis, a copy of "A Brief History of Time" and the script for one of his appearances on "The Simpsons." 

In his final book, released Oct. 16, Stephen Hawking tackles big questions about the universe, delving into physics, cosmology, the existence of God and the future direction of humanity.

The late Professor Stephen Hawking revealed his answers to 10 "big questions" he was often asked in a new book published six months after his death.

The final paper that famed physicist Stephen Hawking worked on before he passed away deals with a topic bigger than Hawking's legacy.

The Large Hadron Collider (LHC), the world's largest atom smasher, just discovered at least two previously unknown particles.

The study of the subatomic world has revolutionized our understanding of the laws of the universe and given humanity unprecedented insights into deep questions. Historically, these questions have been in the philosophical realm: How did the universe come into existence? Why is the universe the way it is? Why is there something, instead of nothing?

Scientists have reached a “milestone” in a technique of semi-artificial photosynthesis that could eventually create an “unlimited source of renewable energy,” according to a new study.

It's the age-old question that always sparks debate.

Once again, scientists have shown that Albert Einstein's theory of special relativity is right — this time, thanks to a particle detector buried deep beneath Antarctica.
