The Earth is small. Our bodies and vision are smaller. Every second the universe expands and creates new stars, new galaxies, new planets, and new solar systems. With us sharing the same time and space with the universe we are one and connected. Ever since the the supernova that created our solar system and most of the elements that created our periodic table and that includes the elements that create our body. In short we are created by the fragments of a star. As our body ages throughout our lives we grow weaker and weaker. But, the universe is forever expanding. Expanding into what? Well we will never know the true answers to the universe. If the universe is what holds all of creation and all of space and time what is the universe expanding into. The best possible guess is, nothingness. The universe is expanding into a vast empty space of nothingness, no age, no color, no dark, no light. IF we were able to cross the border between space and nothingness what would happen. There are two (probably more) possible outcomes.
1. We cease of age , since we are no longer connected to the space and time of our universe we are nothing and cease of age and pain.
2. We cease to exist, when your are across the border of our universe and nothingness, since the existence of nothingness is there we escape our own existence as well. Your body, and even your own soul will cease to ever exist.
