Purpose - The standard terms of time and space lead to logical contradictions near the borderline of physics. Therefore, we suggest a new term for time and space, which enlarges the understanding but takes the actual knowledge of quantum mechanics into account. Design/methodology/approach - The procedure to define a broader and basic term of time and space is based on the relation between the information stored inside a system, the decision which is to be connected with it and the interaction with other systems. Findings - Fundamental to this new understanding is a definition and an explanation of the terms system, decision and information. Based on these three terms we developed a new understanding of time and space. In which case, it involves a specifying and extension of the present understandings. A meaningful point is that these three terms determine each other as they are open terms. Thus, they must be used in the interactive description before and during their own definition. Originality/value - Produces a new understanding and viewpoint which is enlarged by taking into account the knowledge of quantum mechanics. © Emerald Group Publishing Limited.
