Before the Big Bang: A Twin Universe?

Until very recently, asking what happened at or before the Big Bang was considered by physicists to be a religious question. General relativity theory just doesn’t go there – at T=0, it spews out zeros, infinities, and ...

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 ...

Physics Reveals the Key to a Great Golf Swing

What happens when a golf-loving researcher injures a shoulder and can't play for three months? Rod White, a metrologist (measurement scientist), used the spare time off the course to undertake an analysis that revealed the ...
