Which statement below is INCORRECT about star formation during the beginning of the Universe?

• Stars formed at a rate of 10 times HIGHER than present-day Universe

• The gas eventually became hot and dense for stars to be born

• Large clusters of cloud began to form the first galaxies

• Stars formed at a rate of 10 times SLOWER than present-day Universe

What allowed the formation of stars?

• The dense areas pulled in material because of gravity

• The Universe was filled with clouds of hydrogen and helium gas

• The gas eventually became hot and dense

• All of the above

What do we believe the Universe was like 14 billion years ago?
