The future is time that is to come. The future is not the present or the past. It is later. We have seen many possible futures in science fiction. They range from the world’s polar ice caps melting to nuclear winters. But not all futures are this morbid. We have seen the human race spread all over our universe, humans and aliens living in harmony together all over the universe.
It is very likely that we will make some kind of breakthrough in our ability to travel through space sometime in the next 150 years. This would give us the ability to rule other planets. Ultimately, the earth will die whether it be 1,000 years or 100,000 years. We will be forced to move to another planet then. It’s really just a matter of time. When we do so, what will we discover?
Personally, I think everyone will be speaking the same language in 200 years. A world government definitely seems to be in our future. It is stable and has few wars. Indeed, the only type of wars that can happen is the civil war.
And what if we face aliens? If they are friendly, we would probably benefit a lot from putting our knowledge together. They must have advanced technology to travel for great distances. We could seriously benefit from their technology. But if they aren’t friendly, then we are in trouble. Hope that we have become advanced enough, smart enough, and generally a better race by the time we meet them. But this is all probably being discussed for nothing, because any race out there among the stars is probably as curious as we are about other creatures.
