If extra dimensions of space exist, they must be smaller than about half the width of a human hair, according to new measurements of the strength of gravity at short distances. Researchers found that ...

String theory proposes tiny vibrating strings existing across 10 dimensions, unifying forces and particles beyond the ...

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 ...

Modern multiverse fiction incorporates real physics equations and string theory principles rather than relying on pure ...

String theory has been at the cutting edge of science for the past 50 years, if not longer. Unlike many theories that come and go this has remained at the forefront of the scientific communities’ mind ...

Researchers in Japan have developed what may be the first string-theory model with a natural mechanism for explaining why our universe would seem to exist in three spatial dimensions if it actually ...

Imagine a world unified by a single scientific principle, something that can explain life’s greatest mysteries, from the origin of space and time to gravity and smaller matters, like daydreams. Now ...

Theoretical physicist Lennaert Huiszoon has described a new family of strings in research conducted at the National Institute for Nuclear Physics and High Energy Physics. He investigated so-called ...
