How much of the universe’s ordinary matter is thought to be helium? Does Big Bang theory support this number?
The amount of ordinary matter in the universe that is believed to be helium can be estimated based on current scientific understanding. However, it's important to note that the specific fraction may vary depending on different models and assumptions.
To find an estimate of the total fraction of ordinary matter in the universe that is thought to be helium, you can refer to a concept called the primordial abundance. This refers to the relative abundance of different elements shortly after the Big Bang.
According to the current understanding of cosmology, the Big Bang theory suggests that the universe began with a hot, dense state approximately 13.8 billion years ago. During the early stages of the universe, nucleosynthesis occurred, which is the formation of atomic nuclei.
The abundance of helium in the universe is believed to have been heavily influenced by nucleosynthesis during the primordial era. Observations and calculations indicate that approximately 24% of the ordinary matter in the universe consists of helium, while hydrogen makes up the remaining 76%. These estimates are based on the standard cosmological model known as the Lambda Cold Dark Matter (ΛCDM) model.
It's important to note that this estimation assumes that the observations and models used to determine the cosmic microwave background radiation, which is a key piece of evidence for the Big Bang theory, are accurate. However, scientific knowledge and theories are constantly evolving, so future research may refine or update these estimates.
In summary, according to current scientific understanding and the Big Bang theory, it is estimated that approximately 24% of the ordinary matter in the universe is helium.
