Primordial helium refers to the helium that was formed during the Big Bang nucleosynthesis, approximately 3 to 20 minutes after the Big Bang. This process produced about 25% of the universe's mass in helium, along with hydrogen and trace amounts of other light elements. Unlike helium produced in stars (stellar helium), primordial helium is a remnant of the universe's early conditions and is found in the interstellar medium and as part of the cosmic background. It plays a crucial role in understanding the universe's evolution and the formation of cosmic structures.
