1. Our Earth has made over four billion five hundred million orbits around the Sun.
2. The total biomass of bacteria outweighs the sum of all living animals.
3. Every breath you take contains atoms breathed by almost every person who ever lived.
4. We see in the 'optical' visible frequencies since our eyes have evolved to be sensitive to the sun which emits most of its energy in this range of wavelengths.
5. A train stays on the tracks because the wheels are angled like cones.
6. When you turn a corner on a cycle you point the wheel in the opposite direction of the curve.
7. The universe is expanding incredibly fast and the rate of expansion is increasing with time. Eventually all the other galaxies will disappear from view and our galaxy will be alone in a very cold & dark universe.
8. Without our moon, the Earth would spin chaotically and we would not have a stable climate.
9. If we rescale the history of the Universe to a 24hr clock, dinosaurs ruled the earth for 17 minutes whereas humans have been around for just a few seconds before midnight.
10. Every atom in our bodies was made at the center of a star. Our bodies contain stardust from literally thousands of dead stars.
