Chemistry at the beginning: How molecular reactions influenced the formation of the first stars
Immediately after the Big Bang, which occurred around 13.8 billion years ago, the universe was dominated by unimaginably high temperatures and densities. However, after just a few seconds, it had cooled down enough for the first elements to form, primarily hydrogen and helium. These were still completely ionized at this point, as it took almost 380,000 years for the temperature in the universe to drop enough for neutral atoms to form through rec…
How the universe’s first chemistry helped spark the first stars
Right after the Big Bang, about 13.8 billion years ago, the universe was a hot, dense sea of energy and particles. But in just a few seconds, it cooled down enough for the first elements to form—mainly hydrogen and helium. These elements remained in a charged, or ionized, state for quite some time. It wasn’t […] The post How the universe’s first chemistry helped spark the first stars appeared first on Knowridge Science Report.
