Scientific paper

After a general classification of meaningless questions in science we concentrate on empirically meaningless questions. Introducing the concepts of informationally connected, semiconnected and disconnected observers, a formalism for the analysis of the informational structure of space-time is developed. We discuss some problems of epistemological nature in cosmology and black hole physics. A number of questions like 'What was before the initial singularity of the universe' or 'What is the fate of matter in gravitational collapse inside the event horizon' turn out to be empirically meaningless. We also show that a 'wormhole' does not violate causality for the set of informationally connected observers who do not enter it.
