British physicist and cosmologist Stephen Hawking has been hospitalised in Rome for checks after not feeling well, but his condition is not believed to be serious, a spokesman says.
Hawking, 74, who was in Rome to attend a conference at the Pontifical Academy of Sciences and met Pope Francis on Monday, was taken to Rome's Gemelli hospital on Thursday night.
Both the spokesman and a Vatican source said Hawking, who suffers from motor neurone disease, was not believed to be in serious condition. The Vatican source said plans for Hawking and his entourage to leave on Saturday had not been changed.
Hawking, author of A Brief History of Time, speaks through a computer and travels with a staff that includes two nurses. He gave a talk at the Vatican on November 25 on the origin of the universe.
The Gemelli is considered one of Rome's best hospitals and it is where popes are treated.
His hospitalisation comes a day after astronaut Buzz Aldrin, 86, was evacuated from Antarctica to Christchurch with fluid on his lungs. He was being kept overnight for observation.
