Who cares about the fourth dimension?

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. Daniel Grumiller from the Institute of Theoretical Physics, Vienna University of Technology , can now at least unravel some of the mysteries of quantum gravitation. His results on black holes and gravitational waves are pretty mind-boggling - to say the least. Only recently he won the START prize and will use these funds to engage even more young physicists at the TU Vienna. We perceive the space around us as three-dimensional. According to Einstein, time and space are inseparabely linked.
