This chapter focuses on supermassive black holes, which are sometimes abbreviated “SMBHs.” Stellar-mass black holes are clearly common consequences of stellar evolution, but they are not the only kinds of black holes identified by astronomers. Much more massive black holes are located in the center of many, and perhaps all, galaxies. These black holes are referred to as supermassive black holes. They are responsible for a range of phenomena originating from objects described as active galactic nuclei (AGN), which were first observed in the form of quasi-stellar objects (QSOs) or quasars. AGN are among the most luminous objects in the Universe and can be observed at great distances. The distances can be so great that the light travel time from the AGN to Earth is a large fraction of the age of the Universe. They are therefore often used to probe the evolution of the Universe.Less

The first chapter charts the emerging influence and impact of a travel light ethos from the Edwardian period to modernism. It pays particular attention to the transitional status of the house in Edwardian writing at a time when it was visibly beginning to lose its lustre. The chapter will begin by tracing the genesis of that now-prolific phrase 'house of fiction' to Henry James's belated 1908 Preface to The Portrait of a Lady (1881) and will argue that, contrary to popular usage, the 'house of fiction' originally referred to an amorphous structure on the point of abandonment. It will then look at two conflicting responses to the parallel rise of a culture of portability: Max Beerbohm’s ‘Ichabod’ (1900) and E.M. Forster’s Howards End (1910). The chapter will finish by turning to modernist delineations of a portable culture which has become well-established by the late 1910s.Less
