expansion

Where an object such as a steel rod cools it contracts in length. The universe is different as it cools it expands we are a destiny of the universe and the destiny of the earth is forecast and it doesn't matter what humans do it is destined any way. This is fact. Matter and anti matter had a collision an Armageddon if you like. Mass finally win out and the anti matter gets beaten and this turns into mass sticks to matter if you like. Thus mass was formed.
