Those stars and colours you see when you rub your eyes are called phosphenes.

Have you ever closed your eyes, rubbed them and seen stars? Or at least little pops of light? It turns out that those pops of light have a name: phosphenes.

They are a phenomenon characterized by seeing light without light actually entering the eye. This rubbing mechanically stimulates the cells of the retina causing this effect. Sometimes, these phosphenes can still be seen for moments after you open your eyes.

Meditators have also reported experiencing phosphenes, and they have actually been known since antiquity. Ancient Greeks described them. Other reasons people ‘see stars’ are because of sneezing, coughing, blowing your nose or receiving a blow to the head.

The total weight of all the ants on Earth is about the same as the weight of all the humans on earth.

Unless you leave food out and attract them, humans rarely have a need to think about ants. They're tiny, not poisonous and not particularly terrifying, like say, spiders. However, they far outnumber humans on earth--by one million to one!

Funnily enough, they are also roughly a millionth of a human in size too. Do the math--the total weight of all the ants on earth matches the total weight of the entire human population.

There are 10,000 different types of ants and they've been around for a long time. Ancients ants have been discovered in fossilized sap from 100 million years ago!

Over time, ants have changed very little. Their way of life and survival is successful. Some scientists attribute this to their unselfish ways. Ants live in colonies and bring their prey back to their many relatives to share.
