Cosmic information, the cosmological constant and the amplitude of primordial perturbations
A unique feature of gravity is its ability to control the information accessible to any specific observer. We quantify the notion of cosmic information (‘CosmIn’) for an eternal observer in the universe. Demanding the finiteness of CosmIn requires the universe to have a late-time accelerated expansi...
