You think you know everything? Laws of physics, mechanics, gravity.... Well, it turns out that you probably don't. Here is a list of 10 stunning facts to prove that we have to learn so much more in order to understand the world we live in!
1. There is enough DNA in an average person’s body to stretch from the sun to Pluto and back — 17 times
2. The average human body carries ten times more bacterial cells than human cells
3. It can take a photon 40,000 years to travel from the core of the sun to its surface, but only 8 minutes to travel the rest of the way to Earth
4. At over 2000 kilometers long, The Great Barrier Reef is the largest living structure on Earth
5. There are 8 times as many atoms in a teaspoonful of water as there are teaspoonfuls of water in the Atlantic ocean
6. The average person walks the equivalent of five times around the world in a lifetime
7. When Helium is cooled to almost absolute zero (-460°F or -273°C), the lowest temperature possible, it becomes a liquid with surprising properties: it flows against gravity and will start running up and over the lip of a glass container!
8. If Betelgeuse would explode transiting from the red super giant stage to supernova then our sky would light continuously for two months. It can happen anytime, within a couple of thousand years, tomorrow or even now
9. An individual blood cell takes about 60 seconds to make a complete circuit of the body
10. The known universe is made up of 50,000,000,000 galaxies. There are between 100,000,000,000 and 1,000,000,000,000 stars in a normal galaxy. In the Milky Way alone there might be as many 100,000,000 planets. Still think you’re alone?
