An anonymous reader writes: MSNBC reports that British physicist Stephen Hawking will experience a zero gravity airplane flight on April 26. Although the 65-year-old professor is disabled from a neurodegenerative disease, he will be able to make the flight with assistance and medical monitoring. 'As someone who has studied gravity and black holes all of my life, I am excited to experience, firsthand, weightlessness and a zero-gravity environment,' said Hawking. 'I am thankful to Zero Gravity Corp. for making this experience available to the general public, especially for disabled individuals.' The weightless flight will be a step towards Hawking's goal of a suborbital spaceflight with Richard Branson's Virgin Galactic.
