So.....I have such a huge vacant space I call "Things I don't know". So I'm going to start a new "Things I didn't know" list. Here's my first few entries.
- If a tiger loses all his hair, he’ll still be striped. Tiger stripes are like fingerprints, each individual cat’s markings are unique. And they’re not just hair, the stripes are in their skin. Seems to be a thing with cats, since your house cat’s fur markings are also skin deep!
- Strange but true. There are more microbial cells in your body than cells that have your own DNA. As NPR’s Robert Krulwich reported in 2006, the human body has 20 times more microbes than cells! I guess that pretty well justifies the “Imperial We.”
- There are more insects in just one square mile of fertile soil than there are human beings on the entire planet!
- The average person manages to consume about 430 insects every year of their lives, whether they intended to or not! And no, not all “average” people ride motorcycles.
- The interstellar gas cloud that comprises Sagittarius B contains a billion billion billion (yes, that’s three orders of billion) liters of alcohol. This factoid is bound to be a big hit at the pub!
- The density of the planet Saturn is lower than water, so if you could put it in the ocean it would float! (Our own planet Earth is the densest in our entire solar system. It would definitely sink)
- The acceleration rate of a flea jumping off a dog is 20 times the acceleration of the space shuttle during launch! Can JPL reverse engineer that?
- How Long Can a Germ Live? The current championship crown belongs to an 8 million year old bacterium that was taken from the oldest known ice on planet Earth, and is now happily reproducing again in a laboratory petrie dish.
- Cells in the body are continuously renewed. No cell in your body is more than seven years old. Taste buds are replaced every ten days!
- 10% of all the humans who have ever lived are alive in the world right now.
- If you eat Polar Bear liver, you will die. Humans can't handle that much vitamin A.
- Dead ppl can get goosebumps!! But not because of the same reasons living people do. Just as a deceased person experiences rigor mortis of their muscles. Their hair follicle do much the same thing, which results in the appearance of goosebumps.
- The woolly mammoth was still around when the pyramids were being built.
- The word “gas” was coined in 1600 by a Dutch chemist called Van Helmont. It’s the most successful ever invention of a word by a known individual.
- If you were to remove the empty space within atoms, you could fit earth's entire human population into the volume of an average size apple.
- Completely blind ppl don't see blackness. They see nothing.
- It can take an individual photon 40,000 years to travel from the sun's core to its surface but then only take another 8 minutes to reach Earth.
- The poet W. H. Auden helpfully suggested this. “We are here on Earth to help others. What the others are here for, I’ve no idea”.
