Originally from Scotland, Prof Boyle had spent the past 25 years in Australia where, in 2011, he was part of a team awarded the Nobel Prize for physics after they set out to discover how fast the universe was decelerating.
Prof Boyle, who at the time was working for the Australian Astronomical Observatory, said he joined the team of about six people, based at the University of California, in the late 1980s.
"Nobody took us seriously — we were just a bunch of young people trying to do something ... we made lots and lots of mistakes to start with."
In 1998, the "Supernova Cosmology Project" group published a paper showing the universe was, in fact, accelerating.
