Long-term astrophysical processes

Abstract

Our understanding of the universe has advanced significantly, with precise measurements of cosmological parameters leading to a consolidated model that predicts its future evolution. This model suggests that the universe will continue to expand indefinitely, allowing for a vast array of astronomical events to occur. While the threat of cosmic interventions like asteroid impacts and supernovae will increase in the long term, even more fantastic events are predicted to occur on extremely long timescales, vastly exceeding the current age of the universe. These projections, based on our understanding of astronomy and physics, offer a framework for exploring the future of the cosmos, although uncertainties inevitably grow as we delve further into time.
