Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a ...

In today’s Academic Minute, Dr. Ali Nayeri of Chapman University discusses the explanatory power of string theory cosmology. Ali Nayeri is an assistant professor of physics in the Schmid College of ...

(PhysOrg.com) -- Researchers describe how to carry out the first experimental test of string theory in a paper published tomorrow in Physical Review Letters. String theory was originally developed to ...

String theory — the concept that all particles can be represented as strings or string-loops of incredibly minute length, oscillating at various frequencies — was initially developed to help explain ...

A detailed look at the Universe reveals that it's made of matter and not antimatter, that dark matter and dark energy are required, and that we don't know the origin of any of these mysteries. However ...

String theory proposes that the fundamental constituents of the universe are one-dimensional “strings” rather than point-like particles. What we perceive as particles are actually vibrations in loops ...

String theory's equations give rise to a near infinite variety of potential universes in a 'landscape.' This landscape is surrounded by a 'swampland' of solutions that are incompatible with any ...

Abstract, mathematically complex and (so far) unsupported by direct experimental evidence, string theory attracts plenty of criticism. Yet it remains an incredibly active area of research, with ...

NOVA: In the '60s and '70s when there were tremendous breakthroughs in particle physics, how would you describe the relationship between theory and experiment? Glashow: I was at the University of ...

The problem with string theory, according to some physicists, is that it makes too many universes. It predicts not one but some 10 500 versions of spacetime, each with its own laws of physics. But ...

Could some observations from a faraway galaxy add up to a refutation of string theory? Researchers who study data from NASA’s Chandra Observatory think so. It’s difficult to prove something’s absence ...
