The Helium-3 isotope is less stable than helium-4, making it more abundant in fusion reactions in the stars. However, helium-3 was created by the Big Bang explosion, according to astronomical calculations. The problem is that astronomers detect 3 less helium isotopes than those announcing the calculations. Where is the missing helium 3? They have already found an answer: according to the latest mathematical models, inside the stars. The models have been developed by astronomers from the United States and Australia, and are satisfied with the result, because it also coincides with the Big Bang theory.
