High-energy heavy ion collisions, which are studied at RHIC in Brookhaven and soon at the LHC in Geneva, can be a source of light flashes of a few yoctoseconds duration (a septillionth of a second, 10-24 s, ys) - the time that light needs to traverse an atomic nucleus. This is shown in calculations of the light emission of so-called quark-gluon plasmas, which are created in such collisions for extremely short periods of time.

Viennese scientists are trying to understand the mysteries of the holographic principle: How many dimensions are there in our universe? Some of the brightest minds of the world are doing research work in this sector - and still have not succeeded so far: Creating a unified theory of quantum gravitation is often considered to be the 'Holy Grail' of modern science.
