In this bachelor thesis, it is discussed whether the search for invisible decay of positronium could in the near future be used to test models with extra dimensions. To this end, the energy spectrum and decay modes of positronium are discussed. An introduction to different models with extra dimensions is given and it is discussed how positronium could disappear due to the existence of extra dimensions. Limits from other processes on this disappearance rate are acquired and compared to experimental sensitivity which is realistic to obtain in the near future. It is concluded that it is very unlikely that this search for extra dimensions will be viable in the near future because there is too large a discrepancy between the limits and the aspired sensitivity.
