Scientists will find that humans are alone int he universe. Space travel will be normal, or unheard of. We will find Gold. We will find other beings who have pretended to be gods. Human beings will be weak and have huge heads. A race of supermen will develop. People will wear plastic and the world will be covered in concrete. We will gradually go back to hunting and gathering, with nature slowly accepting us back into its arms.
