摘要：
Recently some authors have proven that the anti-de Sitter spacetime is unstable under small perturbations. In our talk we present arguments which show that also the ordinary de Sitter spacetime is unstable. Our arguments are based on the calculation of the superenergy of the de Sitter spacetime.
