They're switching the Large Hadron Collider (LHC) back on, but not everyone is happy with the emphasis on the Higgs Boson 'God particle' because so much other research also happens at Cern.
Physics professor Jon Butterworth, who is a member of the High Energy Physics group on the Atlas experiment at Cern's Large Hadron Collider, told the Today programme's John Humphrys that it would be "tragic" if people thought that they only things worth looking at in science and physics were the big questions.
But he said that "maybe science needs some glamour" because so much of it is incremental with many things going unreported because they do not have a headline.
Paddy Reagan, professor of nuclear physics at the University of Surrey, insisted it was "great to have big high profile projects".
He lamented the fact that there are not big flagship projects like sending men to the moon for a younger generation.
"There is a danger", he said, science is condensed into "a one-line media friendly sound bite".
Professor Butterworth said there was much more to learn at Cern than simply about the so-called "god particle".
"It's an important question but not the only question", he said.
