Whenever we have ventured into new experimental territory, we’ve discovered that our previous “knowledge” was woefully incomplete. So what to make of Italian physicist Carlo Rovelli?
"We simply cannot probe the universe at these scales using current methods, because it would require a particle accelerator the size of a small galaxy. So – for now, at least – our search for the nature of reality is in the hands of the mathematicians and theorists. And, as Einstein would tell us, that is far from ideal."
