Publisher's Synopsis
Seminar paper from the year 2019 in the subject Astronomy, grade: 2,00, Christian-Albrechts-University of Kiel, language: English, abstract: Embark on a groundbreaking exploration of the cosmos, where the accelerating expansion of the universe takes center stage. This compelling investigation delves into the enigmatic nature of the Hubble parameter, dissecting its intricate relationship with the celebrated Hubble constant and challenging conventional understanding of their interplay. Unravel the mysteries of cosmic expansion as we journey from our local cosmic neighborhood to the distant cosmic horizon, venturing back in time to half the universe's age. Discover how the expansion velocity and expansion acceleration influence the very fabric of spacetime, shaping our comprehension of the universe's evolution. Through meticulous analysis and innovative algorithms, this study not only elucidates the present state of cosmic expansion but also dares to predict the future behavior of the Hubble parameter, offering profound insights into the destiny of our universe. Grasp the implications of varying Hubble constant values on the Hubble parameter's trajectory and explore the pivotal role of dark energy in driving the universe's accelerating expansion. Confront the ongoing debate surrounding the precise measurement of the Hubble constant and its profound impact on cosmological models. From the familiar raisin bread model to the complexities of Einstein's general relativity and critical density, this exploration navigates the core concepts underpinning our understanding of the cosmos. This captivating synthesis of cosmology, astrophysics, and theoretical physics is essential reading for anyone seeking a deeper understanding of the universe's expansion and the dynamic interplay of the Hubble parameter, expansion velocity, expansion acceleration, the cosmic horizon, and the elusive dark energy. Delve into the time-dependent behavior of the Hubble parameter and its implications
