Abstract 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 expansion. Combining the introduction of CosmIn with generic features of the quantum structure of spacetime (e.g., the holographic principle), we present a holistic model for cosmology. We show… Expand
