8Be has a very short half-life of about 7×10−17 s that contributes to its significant cosmological role, as elements heavier than beryllium could not have been produced by nuclear fusion in the Big Bang.
8Be har en meget kort halveringstid på omkring 7×10−17 s, der bidrager til dets væsentlige kosmologiske rolle, da grundstoffer, der er tungere end beryllium, ikke kunne være produceret af kernefusion i Big Bang.
