Stop. Look around. All things, visible or not, are made of particles so tiny that many find their sizes difficult to comprehend. Far removed from our everyday experiences, they move at rapid speeds ...

Experimental physicists study the strong force; string theorists try to calculate its effects. Together, they are finding common ground, where string theory can be applied to the physics of ...

Imagine you are sitting in a big symphony hall, and you’re listening to an orchestra play for the first time. The orchestra is performing a Violin Concerto by Beethoven. As the soloist runs her hands ...

STRING theory: you love it or loathe it. To some it represents our best hope for a route to a “theory of everything”; others portray it as anything from a mathematically obtuse minefield to a ...

String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

String theory strutted onto the scene some 30 years ago as perfection itself, a promise of elegant simplicity that would solve knotty problems in fundamental physics—including the notoriously ...

The Large Hadron Collider: evidence for intrinsic charm quarks in protons has been found in LHC data. (Courtesy: Maximilien Brice/CERN) A 40-year-old debate about charm quarks in protons may have been ...

Why strings? What are they made of? How did physicists even come up with this bizarre idea? And what’s all this nonsense of extra dimensions? PBS Space Time is available to stream on pbs.org and the ...
