How many stars have died?

It's estimated that throughout the history of the universe, billions of stars have died. Stars have life cycles that can span millions to billions of years, and many have already reached the end of their lives, transitioning into white dwarfs, neutron stars, or black holes, depending on their initial mass. Given the vast number of stars in the universe, particularly in galaxies, the number of stars that have died is likely in the trillions. However, precise counting is impossible due to the immense scale and complexity of the cosmos.
