WebIt took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms. These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe. Present observations suggest that the first stars formed from clouds of gas around 150–200 million years after the Big Bang.

WebDuring the formation of the universe some 14 billion years ago in the so-called ‘Big Bang’, only the lightest elements were formed – hydrogen and helium along with trace amounts of lithium and beryllium. As t he … WebThe first element produced would be hydrogen. Giant clouds of these primordial elements would then form stars and galaxies. Other elements were formed by fusion within the stars. All heavy atoms (metals) were formed in stars, by fusion, billions of years before out planet even existed! Inorganic elements (and you!) are made of star stuff. mobacken racing

WebThus, only the three lightest elements—hydrogen, helium, and a small amount of lithium—were formed in appreciable abundances at the beginning. The heavier elements formed later in stars. Since the 1940s, many astronomers and physicists have worked on a detailed theory of what happened in the early stages of the universe. WebRoughly three minutes after the Big Bang itself, the temperature of the Universe rapidly cooled from its phenomenal 10^32 Kelvin to approximately 10^9 Kelvin. At this temperature, nucleosynthesis, or the production of light elements, could take place.

WebFeb 26, 2016 · The early stars are massive and short-lived. They consume their hydrogen, helium and lithium and produce heavier elements. When these stars die with a bang they spread the elements of life, carbon and oxygen, throughout the universe. New stars condense and new planets form from these heavier elements. The stage is set for life to … WebAnd they were all there. Recent studies of the cosmic background radiation, using special satellites such as the WMAP satellite, have shown that, in fact, there were tiny differences in the temperature of the cosmic background radiation. Some regions, for example, were just a thousandth of a degree hotter than other regions.
