9. Blood is not red
Blood inside our veins is actually the color blue. Blood only appears Red when it makes contact with oxygen.

8. The Sun is 93,000,000 miles away
This number is equivalent to roughly 390 times the distance from the Earth to the Moon. It is also like circling the Earth approximately 2320 times from the equator.

7. Mosquito Repellents don’t work
At least not in the sense that we understand. Instead of repelling, they actually just hide us from Mosquito’s senses.

2. Big Bang and Evolution are just theories
Our society tends to think of Evolution and Cosmology as scientific facts because they tend to be universally accepted ideas, despite the fact that neither can be proven.

1. Matter is mostly empty space
If you think about it, on the molecular level, atoms are very small and the distance between the nucleus and electrons is very great, compared to their size. Once you get the image of the space between atoms in your head, just multiply that countless times over and you have that much space with matter.
