Dark Energy by Varun Sahni

Explore the mysteries of dark energy in this lecture by Varun Sahni, part of the "Cosmology - The Next Decade" program at the International Centre for Theoretical Sciences. Delve into the puzzling nature of dark energy, its potential dynamical properties, and its implications for Einstein's general relativity at cosmological scales. Examine how this mysterious component of the Universe fits into the Lambda cold dark matter (LCDM) paradigm and consider the possibility of modifications to our understanding of gravity at cosmic levels. Gain insights into the latest theories and observational evidence surrounding dark energy as part of a comprehensive exploration of modern cosmology's most intriguing questions.
