Could a particle accelerator actually end up making a black hole on Earth? It’s not as far-fetched as it might seem.
“I hope you’ll make black holes,” Stephen said with a broad smile. We exited the cargo lift that had taken us underground into the five-story cavern housing the ATLAS experiment at the CERN lab, the legendary European Organization for Nuclear Research near Geneva. CERN’s director general, Rolf Heuer, shuffled his feet uneasily.
Why wasn’t it entirely unreasonable though for Stephen—and Heuer too, I think—to hope that it might be possible to produce black holes at the LHC? We usually think of black holes as the collapsed remnants of massive stars. This is too limited a view, however, for anything can become a black hole if squeezed into a sufficiently small volume.
Its theoretical underpinnings in terms of quantum fields profoundly shape how the Standard Model conceives the microscopic workings of the particle world. Take the interaction between two electrons. When two electrons approach each other they deflect and scatter because like electric charges repel. The Standard Model describes this process in a tangible manner in terms of the exchange of a photon between the two electrons.
