Hello again mr. @firepower!
I already post my comment in Steem.chat-contest channel
Anyway, Im gonna post it here too...
If I were sent back in time about 500 years without any object from this century, including clothes, how would I prove I’m from the future?
Let's see first what’s happening in the world, five hundred years ago. We would be talking about the time of the colony, Christopher Columbus has already discovered America (he is on his fourth trip) and the Spanish empire (Spain and Portugal) begins to spread throughout the American territory. Things do not look very good for Native Americans (both from north and south). However, France, Spain, Roman Empire, England, the Republic of Venice, the Papal States and most of the Italian city-states, as well as the Ottoman Empire are in a conflict called the great Italian wars. In short, in Europe there's war and in America they are killing the natives.
Let's obviate the fact that they could recognize me as a sorcerer or a diabolical entity who has to be burned at the stake, because practically I know more than everybody in all aspects (As a human from the future, I have 500 years of evolution). Remember, the New York Times has more information in one day than 10 people together could have in all their lives, 500 years ago (approximately).
My advantage is that I speak Spanish too; and the Spanish colony is the one that rules. So I would have no problem communicating. As I mentioned before, my knowledge of physics, chemistry, mathematics and geography is enough to show that I come from the future and I am referring to the knowledge obtained at the highschool level and a little from the college level. I can make a compass and know where the sites are in the whole world. I know that there will be an eclipse for December of the year 1518. Undoubtedly, what I must do is to keep quiet, since anything I say would show my evolutionary superiority.
The question would not be how do I prove that I'm from the future but that I would do with my knowledge: I would avoid the extinction of the Native American races, f**k yeah!
Thanks for the contest. It was very interesting.
Cheers!
