Every time you shuffle a deck of cards, the resulting order has almost certainly never existed before in the history of the universe.
The average person contains about 0.2 milligrams of gold, mostly dissolved in their blood.
Diamonds can be made from peanut butter by replicating the extreme pressure found deep within the Earth.
Einstein's brain was preserved after his death and has been studied by scientists ever since.
A cubic inch of bone can bear a load of 19,000 pounds — roughly the weight of five standard pickup trucks.
Antimatter is the most expensive substance on Earth — producing one gram would cost about 62.5 trillion dollars.
Graphene is a single layer of carbon atoms arranged in a hexagonal lattice and is 200 times stronger than steel.
The speed of light in a vacuum is exactly 299,792,458 meters per second.
Quantum entanglement allows two particles to be linked so that a change to one instantly affects the other, regardless of distance.
There are more ways to shuffle a standard deck of 52 cards than there are atoms on Earth.
Helium becomes a superfluid at temperatures near absolute zero, flowing with zero viscosity and even climbing up the walls of containers.
Sound travels about 4.3 times faster through water than through air.
The smell of freshly cut grass is actually a chemical distress signal released by the plant.
Bananas are naturally radioactive because they contain potassium-40.
If you squeezed out all the empty space in atoms, the entire human race could fit inside a sugar cube.
Glass is technically neither a solid nor a liquid — it is an amorphous solid.
Hot water freezes faster than cold water under certain conditions, a phenomenon known as the Mpemba effect.
A single bolt of lightning contains enough energy to toast about 100,000 slices of bread.
Water can boil and freeze at the same time under specific conditions known as the triple point.
The human brain can store approximately 2.5 petabytes of information, equivalent to about 3 million hours of TV shows.
Humans are bioluminescent — we glow in the dark, but the light is 1,000 times weaker than what our eyes can detect.
The average person generates enough body heat in 30 minutes to boil half a gallon of water.
Nerve impulses can travel through the body at speeds up to 268 miles per hour.
The average person walks about 100,000 miles in their lifetime — the equivalent of walking around the Earth four times.
Humans share approximately 60% of their DNA with bananas.
Parrots can learn to use words in context and understand concepts like shape, color, and number.
Tardigrades can survive the vacuum of space, extreme radiation, and temperatures ranging from near absolute zero to over 300 degrees Fahrenheit.
Axolotls can regenerate their limbs, heart, spinal cord, and even parts of their brain.
There are more possible iterations of a game of chess than there are atoms in the observable universe.
If two pieces of the same type of metal touch in space, they will permanently bond together due to cold welding.
A teaspoon of neutron star material would weigh about 6 billion tons on Earth.
The star-nosed mole's star can detect over 22,000 sensory impulses per second.
The axolotl has been a model organism for regeneration research for over 150 years.
Some species of spider can generate electricity statically — using it to enhance silk adhesion.
The vampire bat's saliva contains an anticoagulant — now used as a drug to treat stroke patients.
The tardigrade's survival of space exposure was in cryptobiosis — a state of suspended animation.
Firefly light is cold — less than 1/100th of a percent of the energy is heat.
The naked mole rat feels no pain from acid — a unique adaptation to high-CO₂ underground environments.
The axolotl's genome is 10 times larger than the human genome — yet much of it is non-coding.
The wood frog produces cryoprotectants that prevent cell damage when it freezes solid.
The immortal jellyfish (Turritopsis dohrnii) can reverse its life cycle — reverting from adult to juvenile indefinitely.
Spider silk can absorb more energy before breaking than any man-made material.
Naked mole rats can survive 18 minutes without oxygen — by switching to anaerobic fructose metabolism.
Pistol shrimp can produce a cavitation bubble whose temperature briefly exceeds the surface of the sun.
Tardigrades have survived exposure to the vacuum of outer space — the only animal known to do so unprotected.
The archerfish adjusts for light refraction when targeting insects above the water surface.
The pistol shrimp can produce cavitation bubbles 8,000°F for a fraction of a second when it snaps its claw.
The first gravitational wave detection in 2015 confirmed a prediction Einstein made 100 years earlier.
Some birds have a light-sensitive protein in their eyes that literally allows them to see Earth's magnetic field.
Some species of mantis shrimp have 16 types of color photoreceptors — but process color fundamentally differently than humans.
