KENNEDY SPACE CENTER, UNITED STATES: British cosmologist Stephen Hawking(L) has his communication device adjusted by an aide at a pre-flight press conference 26 April 2007 at Kennedy Space Center, FLorida. Hawking, who has spent his career pondering the nature of gravity from a wheelchair, is set to experience weightlessness during a 'vomit comet' flight in Florida Thursday. The idea is to give 'the world's expert on gravity the opportunity to experience zero gravity' said Peter Diamandis the chief executive of the Zero Gravity Corporation. Hawking, 65, the British author of the blockbuster 'A Brief History of Time,' will be surrounded by a medical team on the padded plane as it flies a roller-coaster trajectory to produce periods of weightlessness.

ArXiv.org, Cornell University website which tracks scientific papers before they are published, has a record of the paper including the March 2018 update.
According to The Sunday Times, the contents of the paper sets out the mathematics necessary for a deep-space probe to collect evidence which might prove that other universes exist.
The highly theoretical work posits that evidence of the multiverse should be measurable in background radiation dating to the beginning of time. This in turn could be measured by a deep-space probe with the right sensors on-board.
Thomas Hertog, a physics professor who co-authored the paper with Hawking, said the paper aimed "to transform the idea of a multiverse into a testable scientific framework."
Hertog, who works at KU Leuven University in Belgium, told the Sunday Times he met with Hawking in person to get final approval before submitting the paper.
The newspaper said that if such proof is ever found it would make the scientists behind it likely candidates for a Nobel Prize.
