What good is it?
Particle physicists try to avoid forecasting the applications of an experimental advance before the actual advance is confirmed, but in the past, advances on a par with the discovery of the Higgs boson have had lots of beneficial applications, and some that are more questionable. The rise of nuclear power and nuclear weaponry is a prime example of that double-edged sword.
The discovery of antimatter is what made medical PET scanning possible, and antimatter propulsion could eventually play a part in interstellar travel, just like on "Star Trek." Particle accelerators have opened the way to medical treatments such as proton eye therapy — as well as advances in materials science, thanks to neutron scattering.
It's conceivable that the discoveries made at the Large Hadron Collider will eventually point to new sources of energy, Michio Kaku, a physicist at City College of New York, told me during a discussion of the LHC's promise and peril. And if the discovery of the Higgs leads to fresh insights into the fabric of the universe, it's conceivable that we could take advantage of the as-yet-unknown weave of that fabric for communication or transportation. Who knows? Maybe this is how "Star Trek" gets its start.
