It's a joke.
You were joking about that?
Because Light consists of particles and wavelengths together in two different properties. Like you said before.
Riot's pretty stupid.
No.
Also, in regards to:
Columbus found out for himself that the earth was flat by sailing on the ocean. It doesn't take a trip to space to find out, hell, you can even tell it's round by looking at its loving shadow on the moon.
People back then never thought of that. It seems obvious but people of that time never could take these facts together to produce one.
The Mayans looked out into the Ocean and saw nothing. There was something wrong, there were Spanish ships closing in onto the shores. For the indians these ships looked like nothing, ordinary rocks maybe? Until they found out that these things were getting closer and they found that there were people on board.
Many things seem obvious to you now, but back then they were the wonders of the world that could never be answered.
