Abstract:

Quantum theory and the theory of relativity lead to sets of laws that work fantastically. Quantum field theory being accurate to about one part in 1011, general relativity has been tested to be correct to one part in 1014. However, if we put them together we inevitably obtain irreconcilable differences; both theories are mutually exclusive. In this article, the situation is analyzed in connection with the cosmological constant because this constant connects quantum phenomena with space-time features of general theory of relativity. It turns out that both theories have a serious vacuum (space-time) problem: within quantum field theory the energy density of the vacuum is obviously much too large and, on the other hand, the general theory of relativity does not fulfill Mach's principle. Proposals are discussed to overcome these problems.
