Universe from the Big Bang theory to the theory of Great Annihilation At the beginning was something, what is called the Big Bang Just after the Big Bang was only subatomic particles existed. There were many explosions during the Big Bang when particles and antiparticles touched together. And just before the hot Big Bang happened thing, what is called a cold Big Bang. During that process, a large number of particles released to the universe, and could those particles forming the thing, what is called "dark matter"? The thing is that when those particles released to the universe there was nothing. And when the particles came to absolute emptiness, there was nothing and even radiation has not in that space those particles were not rotated. When the hot big bang started those particles just flew too fast, and the radiation couldn't reach them. This means that those particles couldn't start the rotation movement, which is called spin. That thing makes them u
