Astrophysicists create “time machine” simulations to observe the life cycle of ancestral galaxy cities
Scientists create “time machine” simulations that study the life cycle of ancestral galaxy cities. Many processes in astrophysics take a long time, which makes their evolution difficult to study. For example, a star like our sun has a lifespan of about 10 billion years, and galaxies have evolved over billions of years. One way astrophysicists …
