The Journey from Einstein's Cosmological Constant to Dark Energy

EasyChair Preprint no. 11370

10 pagesDate: November 22, 2023


The odyssey from Einstein's cosmological constant to dark energy is a captivating narrative in cosmology's history. This paper navigates this transformative journey, charting the evolution of cosmological theories, pivotal contributions, and ethical considerations. Einstein introduced the cosmological constant in 1917, seeking a static universe. Later, Friedmann and Hubble reshaped this notion with expanding universe models, challenging Einstein's hypothesis. Lesser-known scientists like Wirtz, de Sitter, and Lemaître furthered these discoveries, leading to Einstein's shift towards an expanding universe, abandoning the cosmological constant. The revelation of dark energy, inferred from distant supernovae, marked a new frontier in cosmology. Ethical discourse underscores the preservation of historical context, scientific integrity, and the transition from a static universe concept to the mystery of dark energy.
