Main research findings
As known, data is a valuable resource nowadays. But what about what we do not know? In what way does our lack of knowledge affect the description of reality and, what is even more important, how can we use this for our own benefit?Complete knowledge about a system presupposes its being in a certain state. If some information is unavailable, one should deal with probability distributions. This means that system properties are determined both by what we know and what we do not. The latter one can be estimated with information entropy, which is the main instrumentused throughout the presented research. The aim of this thesis is to demonstrate how information entropy can help us solve intriguing problems in high energy physics and astrophysics.The study was conducted for different systems. It demonstrates that microscopic description affects the entropy and pinpoints with greater precision the (tri)critical point of the excited medium emerging in ultrarelativistic high energy collisions. Also, the contribution of the Unruh radiation of spinless particles to the Bekenstein-Hawking radiation entropy of Schwarzschild black holes is calculated.
