Webb12 sep. 2024 · Scientist now believe that many heavy elements found on Earth and throughout the universe were originally synthesized by fusion within the hot cores of the stars. This process is known as nucleosynthesis. For example, in lighter stars, hydrogen combines to form helium through the proton-proton chain. WebbAlthough the principle is simple, they face several challenges. At 150 million °C, hydrogen atoms crush and end up forming an ‘electrically-charged gas’ known as plasma. They …
