Scientific narratives about cosmology often present black holes as frightening objects of both creation and destruction, the centres of which are concealed behind event horizons. According to studies, black holes are capable of distorting time and tearing apart anything that plunges toward them. This article asks what the latest knowledge about the properties of black holes can contribute to philosophical understandings of being and time. Drawing on both scientific and narrative constructions of black holes in books written by physicists, the (...) article analyzes black holes in relation to Martin Heidegger’s philosophy of ontology in Being and Time. The article argues that the topics of concealment, time, and mortality form interrelated points of intersection among scientific constructions of black holes and Heidegger’s philosophy. First, scientific commentaries on the concealment of singularities speak to Heidegger’s interpretation of the ways being is concealed in modern society. Second, with regard to time, the phenomenon of gravitational redshift invokes Heidegger’s criticisms of clock time and, by extension, notions of infinitude. On the other hand, theories about Hawking radiation and the decay of black holes also invoke Heidegger’s thesis that time subsists predominantly as a passing away toward the cessation of existence. Third and finally, Heidegger’s renowned and controversial explication of mortality helps frame black holes symbolically as forward-projections toward the impossibility of existence. Bringing these three subjects together, the article concludes that, as Heideggerian symbols of being and time, black holes represent projections toward the possibility of impossible modes and forms of existence. In this sense, black holes emblematize a relationship between being and time that marks the potential limits of existence, as humanity and science understand it. (shrink)

The author investigates the prospects of holistic ethics in the contemporary world. From the standpoint of individual existence observed three modes of ethical attitude towards the world in their historic genesis: home, environment, and common world. The ancient idea of home as a place of love and revelation of God was eroded by the expansion of human civilization on the natural, social, and cosmic scale. This process is reflected in the concept of a multiform environment as a source of material, (...) biological, economic, political, cultural possibilities, and a space of physical, social, and informational mobility. The crises of those environments put the problem of the proper ethical norms and values for human survival and further development. The ethical dimension of its solution presents the idea of a common world and the relevant ethical principles of advocacy, responsibility, solidarity, justice with the aim of consensus on the basis of a rational discourse where people represent all the other being’s interests. Thus, based on regularly open for better arguments discussion, the author views the possibility of the formation of a cosmos friendly ethics. (shrink)
