How is the overall process of stellar evolution viewed across cosmic time, despite an individual star's life being a one-way trip?

Answer

Inherently cyclical due to matter recycling

While one star moves linearly from birth to death, the heavy elements forged in massive stars and scattered by supernovae become the raw materials for the next generation of stars, making the process cyclical across cosmic time.
