The stars have aligned for physics fans hoping to get their hands on a Stephen Hawking relic.
Wheelchairs, scientific papers, and even a script from The Simpsons once belonging to the late physicist will be auctioned off starting Oct. 31, The Associated Press reports. Proceeds from the online sale will benefit Hawking's foundation and the Motor Neurone Disease Association.
Hawking was given just a few months to live when he was diagnosed with ALS at age 22, but famously produced cosmological theories from a wheelchair until he died at 76 in March. His oldest chair will be up for auction, as well as a newer motorized model expected to fetch up to $19,500, per AP.
The auction's premier item is expected to be a signed copy of Hawking's doctoral thesis, "Properties of Expanding Universes." It's estimated to fetch up to $195,000, AP says. Lower-budget items include a bomber jacket, a copy of A Brief History of Time signed with Hawkings' thumbprint, and a script from one of Hawkings' several Simpsons appearances. The rest of Hawkings' scientific archive will be preserved by the British government.
Papers by Charles Darwin, Albert Einstein, and other science legends will all be up for grabs at the same auction, CNBC says. If old-school physics is more your thing, drop a bid on a script explaining Isaac Newton's love of alchemy that's expected to go for at least $100,000. Kathryn Krawczyk
