Universe Acceleration

Universe acceleration refers to the observation that the expansion of the universe is speeding up over time. Initially, scientists thought gravity would slow down this expansion, but data from distant supernovae and cosmic microwave background radiation revealed that a mysterious force, called dark energy, is driving this acceleration. This means that galaxies are moving away from each other faster than before. Understanding this phenomenon is crucial for comprehending the fate of the universe, suggesting it may continue expanding indefinitely, leading to a more isolated cosmic future.
