8、that event，matter began to form as small dust grains and gasesHow the first stars formed from this dust and gas has been a burning question for years，but a state of-the-art computer simulation now offers the most detailed picture yet of how these first stars in the universe came into existence The c

13、 to form this protostar DrYoshidas simulation also shows that the protostar would likely evolve into a massive star capable of synthesizing(合成)heavy elements，not just in later generations of stars，but soon after the Big Bang Their simulation of the birth of a protostar in the early universe signifie
