The human eye is so sensitive that, if the Earth were flat, you could spot a candle in the dark from 20 miles away
The farthest object visible with the naked eye is the Andromeda galaxy, located 2.6 million light years from Earth,
If you removed all the empty space from between and within every atom making up all humans, you could fit the entire human race into the volume of a sugar cube. The human race (or the atoms that make us) are 99.9999999999999% empty space. In theory, if you removed all that empty space, humanity could fit into the volume of a sugarcube.
Alaska is the northernmost, westernmost, and easternmost U.S. state. Yes, you read correctly – Alaska is both the most Eastern and Western state. Alaska’s Aleutian Islands cross from the Western Hemisphere into the Eastern Hemisphere.
Chances are, a pack of cards have never randomly been shuffled into the same order. If every star in our galaxy had a trillion planets, each with a trillion people living on them, and each of these people has a trillion packs of cards and somehow they manage to make unique shuffles 1,000 times per second, and they’d been doing that since the Big Bang, they’d only just now be starting to repeat shuffles.
One out of every 200 people alive today is a descendant of Genghis Khan.
If a nickel were as big as the Earth, an atom would be the size of a nickel.
1 out of 10 photographs ever taken in human history were taken in the past 12 months
Your blood vessels are long enough to circumnavigate Earth over 12 times. Inside the average human body are 100,000 miles of blood vessels, enough to travel around the 7,900 mile diameter of the Earth.
There are more stars in our universe than grains of sand on all our beaches. There are around 10 sextillion stars in the universe – that’s a 1 followed by 22 zeros. On all our beaches, there’s estimated to be around 5 sextillion grains of sand.
Antarctica is the world’s largest desert
A line of rubik’s cubes in every possible combination could reach the sun over 17 million times. If you had one rubik’s cube for every possible permutation of the cube, and laid them out end to end it would stretch out for 261 light years. For perspective, the sun is 8 light minutes away and the closest star, Proxima Centauri, is four light years from Earth.
If you could fold a piece of paper 42 times, it would be thick enough to reach the moon
There are more nerve connections in your brain than there are stars in the galaxy.
If you have 57 people in a room, there’s a 99% probability that at least two of them share a birthday.
Living inside the tiny hole outside your stomach is an ecosystem the size of a rainforest. From exploring 60 belly buttons, researchers found 2,368 bacterial species, 1,458 of which may be new to science.
The Internet weighs as much as a single strawberry. The vast amount of digital information in motion is made of electrons, just like everything else. It’s estimated that global Internet traffic weighs around 50 grams.
Humans share 50% of their DNA with bananas. While we share 95% of our DNA with chimpanzees, we also share 50% with bananas. Going back in time, we both emerge from the same family tree, the tree of life, and that is why we share common characteristics.
Around 72% of the Earth’s surface is covered in water. To date, we’ve explored only 5% of that massive area.
Human fingers are so sensitive that if they were the size of planet Earth, they could feel the difference between houses and cars.
Plankton produce 50% of the world’s oxygen. Phytoplankton, much like trees and plants, use photosynthesis to convert light into energy. There happens to be a lot of plankton.
Russia has a bigger landmass than Pluto.
There are 16 years worth of video uploaded to YouTube everyday.That translates to a massive 6 billion hours of recorded human history every month.
The deepest part of the ocean is so deep that if Mount Everest were placed at the very bottom, the peak would still be submerged by a mile of water.
