There are parallels between the search for the ‘God particle’ and the search for God Himself, writes Alister McGrath.
In 1994, Nobel Laureate Leon Lederman came up with a nickname for the Higgs boson – the mysterious particle proposed by physicist Peter Higgs back in the 1960s to explain the origin of mass. Journalists loved the name – “the God particle” – which probably explains the huge media interest recently in the work of the Large Hadron Collider. Most scientists hated it, considering it misleading and simplistic. Maybe so. But it certainly got people talking about physics.
And maybe it’s not such a bad nickname after all. Lederman invented the name the “God particle” because it was “so central to the state of physics today, so crucial to our understanding of the structure of matter, yet so elusive.” Nobody had seen it back in 1994. And they’re still not sure whether they’ve really seen it today. Yet this isn’t seen as a massive problem. The idea seemed to make so much sense of things that the existence of the “God particle” has come to be taken for granted. It has become, I would say, a “particle of faith”. The observations themselves didn’t prove the existence of the Higgs boson. Rather, the idea of the Higgs boson explained observations so well that those in the know came to believe it really existed. One day, technology might be good enough to allow it to be actually observed. But we don’t need to wait until then before we start believing in it.
Some tell us that science is about what can be proved. The wise tell us it is really about offering the best explanations of what we see, realising that these explanations often cannot be proved, and may sometimes lie beyond proof. Science often proposes the existence of invisible (and often undetectable) entities – such as dark matter – to explain what can be seen.
