A universe of 10 dimensions

When someone mentions "different dimensions," we tend to think of things like parallel universes – alternate realities that exist parallel to our own, but where things work or happened differently. However, the reality ...

UF physicists win two top international awards

Each year, the American Physical Society prizes honor the world's leading physicists. This year, two of those coveted awards are going to researchers at the University of Florida.

Strict limit on CPT violation from gamma-ray bursts

Kenji Toma (Osaka Univ.), Shinji Mukohyama (Kavli IPMU, Univ. of Tokyo), Daisuke Yonetoku (Kanazawa Univ.) and their colleagues have used the photon polarization in three distant gamma-ray bursts detected by Japanese spacecraft ...

A 40-year-old puzzle of superstring theory solved by supercomputer

A group of three researchers from KEK, Shizuoka University and Osaka University has for the first time revealed the way our universe was born with 3 spatial dimensions from 10-dimensional superstring theory in which spacetime ...

Superstring theory useful for experimental physics

Superstring theory aims to explain the laws of physics from extremely small strings in various states. Theoretical superstring theory is therefore normally not considered to be particularly relevant for practical particle ...
