quantum gravity

Axion monodromy inflation Let us assume that the BICEP2 result is confirmed as cosmological, and indicates primordial gravitational waves generated during inflation. Within the context of inflationary theory, this groundbreaking discovery has important implications for quantum gravity, for which string theory is our leading candidate. String theory contains a rather simple mathematical structure – monodromy […]

THE HOLOGRAPHIC PRINCIPLE

The holographic principle claims gravity in the universe comes from thin, vibrating strings. These strings are holograms of events that take place in a simpler, flatter cosmos. The principle suggests that, like the security chip on your credit card, there is a two-dimensional surface that contains all the information needed to describe a three-dimensional object […]

Cosmology and elementary particle physics

Physics: What We Do and Don’t Know Steven Weinberg In the past fifty years two large branches of physical science have each made a historic transition. I recall both cosmology and elementary particle physics in the early 1960s as cacophonies of competing conjectures. By now in each case we have a widely accepted theory, known […]
