Aayush Shitut- VIII C
|
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 supergiant 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 billion Earth-like planets. Still
think you’re alone?
