Vol. 7 No. 1 (2026): Challenges to the Cosmological Standard Model
This edition of the Astronomy Notebooks (CdA) delves into the complexities of the current state of modern cosmology, exploring in its thematic section the fissures in the standard model of cosmology and outlining future perspectives for our understanding of the universe. It also presents articles on the multi-worlds interpretation of quantum mechanics and its approach in literary fiction; a philosophical essay on Duhem's premise of the relationship between distinct theories and experimentation for the progress of science; and a review of the technical difficulties in detecting gravitational wave signals. In the research articles sections, a Junior Scientific Initiation project discusses the use of Newtonian gravitation in determining the mass of the central black hole of our galaxy; the atmosphere of Mars is contrasted with that of Earth within the context of astrobiology; and a report on a science outreach project in basic education presents the intriguing and rich history of the telescope. Complementing this edition, an annotated translation of Einstein's 1917 article is presented in Portuguese for the first time.
