32、ious“dark matter”of the universe after the Big Bang in order to form this early stage of a star-a protostar with a mass of just one percent of our sunThe simulation reveals how pre-stellar(前恒星的) gases would have actually evolved under the simpler physics of the early universe to form this protostar

33、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 signifies a key step toward the
