In stellar nucleosynthesis, two helium-4 nuclei may collide and fuse into a single beryllium-8 nucleus. Beryllium-8 has an extremely short half-life (6.7(17)×10−17 seconds), and decays back into two helium-4 nuclei. If the beryllium-8 collides with a helium-4 nucleus before decaying, they can fuse into a carbon-12 nuclei. This is called the triple-alpha process, or "helium burning".
George Gamow, in his Big Bang theory, predicted that Be-8 decays too fast to sustain nuclear fusion. This would mean that only Hydrogen, Helium and Lithium would be produced and not the elements which have a higher mass. Fred Hoyle subsequently theorized the Triple-alpha process which would allow for higher elements to be created in stars.
