Thus, if the universe is hot enough (approximately 1015 K, a temperature not exceeded since shortly after the Big Bang), then the electromagnetic force and weak force merge into a combined electroweak force.
Dengan demikian, jika alam semesta cukup panas (kira-kira 1015 K, suhu melebihi hingga tak lama setelah Big Bang), maka gaya elektromagnetik dan gaya lemah bergabung menjadi gaya elektrolemah gabungan.
