    How did the first heavy elements form? How did heavier elements get dispersed throughout the universe?

    The heaviest elements formed by the stars because of their large size hydrogen and helium mixed which created the first heaviest elements. The heavier elements get dispersed by stars having supernovas, where the star comes together to form a ball, and explode. The heaviest element were made 13.8 billion years ago.
  • What caused the universe to be transparent and dark?

    What caused the universe to be transparent and dark?

    The universe cooled and the protons and neutrons connected to helium which caused the universe to be transparent and dark. The universe was roughly 380,000 years old when this took place.
  • What eventually formed at the densest locations?

    What eventually formed at the densest locations?

    Stars eventually formed at the densest locations. Start first formed 4 billion years ago.
