The Earth Has A Heartbeat 💓
The Earth’s inner core rotates faster than the planet’s surface, creating a dynamo effect that generates our magnetic field. This churning, molten iron inner core also produces seismic waves that reverberate through the planet like a heartbeat. Called Earth’s “hum”, this resonant frequency pulses at a very low pitch of 2.5 millihertz, which is too low for humans to hear. But sensors can detect this fundamental vibration that pulses through the Earth like a giant, living organism.
Glass Is A Liquid 💧
You may have heard that old window panes are thicker at the bottom because glass is an extremely slow moving liquid. This myth contains a kernel of truth. Glass is technically neither a solid nor liquid, but an amorphous solid meaning its molecules are rigid like crystals but disordered like liquid. Extremely old glass can show extremely minor flow, so glass is considered a solid that has loosened up over time and slowly flows in a nearly undetectable way.
You Can Hear The Big Bang 🌌
The universe has a faint background noise leftover from the Big Bang called the cosmic microwave background radiation. In 1964, two American astronomers accidentally discovered it while trying to eliminate excess noise from their antenna. This leftover radiation from the birth of the universe sounds like static hiss from an old TV. If you tune an old analog TV to a channel with no signal, about 1% of that static is the primordial background noise from the universe’s creation.
Schrödinger’s Cat Is Both Dead And Alive 🐈
In Erwin Schrödinger’s famous 1935 thought experiment, a cat locked in a box with poison has its fate linked to a random quantum event. According to the Copenhagen interpretation of quantum mechanics, until the box is opened, the cat exists in a superposition of both alive and dead states. This perplexing idea illustrates how particles at the quantum level can exist in multiple states simultaneously until they are measured.
There Are More Trees On Earth Than Stars In The Milky Way 🌲🌟
There are over 3 trillion trees on our planet, compared to 200-400 billion stars in our galaxy. However, there are over 100 billion galaxies in the observable universe containing hundreds of billions of stars each, making the total stellar population very large. many stars are much bigger than trees, so by sheer biomass, trees dominate normal matter on Earth.
Bananas Are Radioactive 🍌☢️
Bananas contain high amounts of potassium, including a tiny amount of radioactive potassium-40 isotope naturally found in nature. The radiation exposure from eating a banana is thousands of times smaller than a dental x-ray and millions of times less than a CT scan, so it is not dangerous. But bananas trigger radiation sensors used at ports to detect smuggled nuclear material enough that they have to make exceptions for banana shipments.
A Year Is Not 365 Days Long 🗓
A year on Earth doesn’t take exactly 365 days. It’s actually closer to 365.25 days. Our calendar years have an extra day added every 4 years (except years divisible by 100 but not 400) to keep it aligned with Earth’s orbit. Earth takes exactly 365.256363004 days to orbit the Sun. This fractional number makes our calendar drift over time, so leap seconds are occasionally added to clocks to keep pace with Earth’s slightly messy orbital timing.
You Are Always Looking Into The Past 🔙
Due to the finite speed of light, everything you see is delayed. It takes time for light to travel from an object to your eyes, so you always see things as they were in the past – even if just a nanosecond ago. The Sun is about 8 light minutes away, so you see it as it was 8 minutes ago. The nearest star Proxima Centauri is 4.2 light years away, so its light shows that star as it was 4 years ago. Distant galaxies are billions of light years away, letting us peer billions of years into the past.
Earth Has A Natural Satellite – The Moon 🌔
The Moon is Earth’s only natural satellite and the 5th largest moon in our solar system. No other planet has a moon as large as ours compared to the size of the planet itself. The Moon orbits Earth at an average distance of about 238,000 miles. Earth and Moon are tidally locked, so the same side of the Moon always faces Earth. The Moon helps stabilize our planet’s wobble and its gravity causes tides. Lunar eclipses happen when Earth passes between the Sun and Moon.
You Can Fit All The Planets Between Earth and Moon 🪐
If you lined up all 8 planets in our solar system end to end, they would comfortably fit in the space between the Earth and Moon. However, some planet’s moons and the Sun would not fit in this space. The average distance between Earth and Moon is about 30 times Earth’s diameter. All planets from Mercury to Neptune are less than 10 times Earth’s diameter, so they would have plenty of room.
Diamonds and Pencils Are Made of the Same Thing ✏️💎
Graphite and diamonds are both different forms of the element carbon. In pencils, carbon atoms are arranged in sheets in an organized crystalline structure, which is soft enough to rub off onto paper. In diamonds, the carbon atoms form an extremely hard tetrahedral crystal structure . But since it’s all the same basic element, you could turn a pencil into a diamond with enough heat and pressure.
There are More Molecules in a Cup of Water Than Cups of Water in All the Oceans 🌊
There are over 3×1024 (3 sextillion) water molecules in just one cup. There are about 1.386 billion cubic kilometers of water in all Earth’s oceans. If you imagine dividing that volume into cup-sized portions of 237ml each, it comes out to just over 5×1019 cups of water in the oceans. So one cup contains 6 orders of magnitude more water molecules than the number of cups of water contained in all the oceans on Earth.
You Are Moving Through Time at Different Speeds ⏱️
Due to relativity, time moves slower for objects moving close to the speed of light. Also, gravity warps time, making time move slower when you are lower down in a gravity well. So even though we don’t perceive it, time moves ever so slightly slower for your feet than your head since Earth’s gravity is pulling stronger on your feet. Plus, time moves a tiny bit faster for you if you are moving compared to a still object.
The Universe Is Mostly Empty Space 🪐
Atoms are mostly empty space. The solid objects around us appear solid because the positive nuclei of atoms are surrounded by negatively charged electrons orbiting at different energy levels. But between these fuzzy clouds of charges lies mostly void. If you removed all the empty space from all the atoms that make up all humans, we would collectively fit into an apple. This illuminates the sheer amount of void in the seeming solidity of all matter.
Clocks Run Slower If They Move Faster ⏱️🚀
Another strange effect of relativity is time dilation – fast moving clocks run more slowly compared to stationary ones. Atomic clocks aboard jets running a tiny fraction faster than stationary clocks on Earth prove this eerie quirk of physics. Also, GPS satellites have to correct for time dilation effects of speed and gravity to stay perfectly synchronized with clocks on Earth’s surface below. The effects are subtle, but prove that time itself speeds up or slows down depending on motion.
There Are More Cells in Your Body Than Stars in the Milky Way 🧬 🌌
Scientists estimate the Milky Way contains between 100-400 billion stars. The human body has 30-37 trillion cells. So a human body has around 100 times more cells than there are stars in our home galaxy. However, our galaxy is just one of trillions in the vast observable universe containing similarly numbers of stars. So in the grand cosmic scale, one human body is a tiny structure by comparison. But it is amazing that each human contains multitudes within.
Light is Affected by Gravity👨🚀
Einstein’s theory of general relativity describes gravity as the warping of spacetime itself. One result of this is that light bends when passing close to a massive object like the Sun due to its gravitational field. Observations of light bending during a 1919 solar eclipse were among the first experimental validations of Einstein’s radical ideas about gravity. This showed that light has mass and is affected by gravity – an unexpected revelation at the time.
Empty Space Isn’t Empty 🪐
What we think of as total vacuum is buzzing with tiny quantum fluctuations that produce transient particles appearing and disappearing incredibly quickly. On very small scales, seemingly empty space behaves like a noisy chaotic soup bubbling with quantum activity. While largely invisible to us, these quantum effects can be measured experimentally and are extremely important in particle physics. So the void of space is not totally calm and empty.
The Universe is Expanding Faster Than Light 🚀
Due to the space between galaxies expanding, most of the visible universe is receding from us faster than the speed of light. But nothing is breaking the cosmic speed limit locally. Expansion stretches the fabric of space itself, so distant galaxies are carried along for the ride. The expansion rate is called the Hubble Constant after Edwin Hubble who first observed it. Recent measurements show the universe is expanding 9% faster than previously thought, a discrepancy suggesting gaps in our cosmological models.
Matter Can Be Created From Pure Energy ☢️
Einstein’s famous equation E=mc2 shows the equivalence of mass and energy. This enables matter creation from pure electromagnetic energy, as long as conservation laws are obeyed. Particle accelerators use immense amounts of energy to collide particles, converting that kinetic energy into matter in the form of exotic subatomic particles like muons. Nuclear reactions in the Sun also convert hydrogen to helium, transforming matter according to Einstein’s equation.
You Are Mostly Empty Space 💀
Atoms are composed mainly of empty space. If an atom were the size of a stadium, the nucleus would be smaller than a marble on the field. Electrons whizz around this tiny nucleus so fast and far away that atoms are almost entirely void. Removing all the empty space from all the atoms in your body would reduce you to a speck smaller than a dust mite. So while we seem solid, each of our atoms and ourselves are over 99.999% empty space!
There are More Ways to Shuffle a Deck of Cards Than Atoms on Earth 🃏
The number of unique card order combinations in a standard 52 card deck is 52 factorial, or 80 unvigintillion. That’s an 8 with 67 zeros after it, vastly more permutations than the roughly 10^50 atoms estimated to be on Earth. To put this in perspective, if every star in the observable universe had 10 billion habitable planets each occupied by 10 billion people constantly shuffling cards, they would need to shuffle for 65 billion years to go through a fraction of the unique combinations.
