FIRST STAR FORMATION – The process by which the first stars were born from primordial gas clouds, influenced by gravity and gas dynamics.

COSMOLOGICAL SIMULATION – A computational method used to model the formation of the first stars and their effects on the universe’s evolution.

EARLY STELLAR EVOLUTION – The study of how the first stars formed, evolved, and contributed to the creation of the first galaxies and black holes.

DARK AGES OF THE UNIVERSE – The period before the first stars formed, when the universe was opaque and no light sources existed.

PRIMORDIAL BLACK HOLES – Hypothetical black holes that may have formed from the collapse of dense regions in the early universe, possibly influencing the first stars.

SUPERMASSIVE STARS – The extremely large stars that likely formed in the early universe and may have led to the creation of black holes.

STELLAR POPULATIONS – The classification of stars based on their age and metallicity, with Population III stars being the earliest.

FIRST LIGHT – The first time stars began emitting light in the universe, marking the transition from the Dark Age to the era of reionization.

BIG BANG NUCLEOSYNTHESIS – The process by which the first elements, including hydrogen, helium, and trace amounts of lithium, were created in the early universe.

METALLICITY – The fraction of elements heavier than hydrogen and helium in a star, which is very low in Population III stars.
