little-known science facts that will change your perspective
In this article, we uncover 35 mind-expanding science facts from physics, astronomy, biology and more that you probably haven’t heard before. Get ready to have your outlook on the world shifted.
🌌 Surprising Facts About Our Unfathomably Vast Universe
Our cosmos contains endless wonders waiting to be discovered. Let’s explore some awe-inspiring secrets about the extent of our universe:
There Are More Stars Than Grains of Sand on Earth
- Scientists estimate over 100 billion trillion stars exist in observable space. That’s 10 stars for every grain of sand on the planet! ✨
It Would Take 225 Million Years to Walk Across Our Galaxy
- At walking speed, it would take a really long time to travel the 100,000 light years across the Milky Way. Better pack a lunch! 🥪👣
We Can Only See 4% of the Universe
- All the stars, planets and gasses make up just 4% of the cosmos. Dark energy (68%) and dark matter (27%) constitute the rest.
🔬 Quantum Physics Defies Common Sense
Peer deeper into the subatomic world, and science starts getting really freaky. These quantum facts seem downright absurd:
A Particle Can Be Two Opposite Things Simultaneously
- Bizarre quantum superposition allows particles to exist in contradictory states before observation fixes one.
Quantum Jumps Occur Instantaneously
- When quantum particles shift energy levels, they teleport discontinuously without traversing space in-between.
A Cat Can Be Both Dead and Alive
- Schrödinger’s famous thought experiment illustrates the bizarre probabilistic nature of unobserved events.
🧠 Consciousness Still Confounds Scientists
The source of conscious experience remains a profound mystery. Explore some puzzling facts science has uncovered about the mind:
No One Can Explain Why We Are Conscious
- There is still no accepted theory on how firing neurons create subjective experience and awareness.
Memories Can Form Without Conscious Processing
- Studies show we can encode memories without paying conscious attention at the time.
Lucid Dreaming Blurs the Lines Between Realities
- In lucid dreams, the brain is awake enough to realize the experience isn’t real while still dreaming.
🦠 Microscopic Life is Everywhere
Microorganisms are found in some surprising places. Let’s investigate some intriguing facts about the tiny critters living all around us:
There are More Microbial Cells in Your Body Than Human Cells
- Only 43% of the cells in the human body are human. The rest are microscopic bacteria, viruses and fungi!
The Deepest Place on Earth is Teeming With Microbes
- Miles below the Earth’s surface there are still 10-100 billion bacteria living in every gram of rock.
Clean Rooms Have Their Own Ecosystems
- Even NASA’s sterile spacecraft assembly rooms host hearty microbes that feed on cleaning chemicals.
⚛️ Mysterious Physics Principles Exist
Dive deeper into physics, and there are phenomena science still cannot fully explain:
No One Knows Why the Laws of Physics Exist
- The values of constants like the speed of light seem arbitrarily fine-tuned to allow humans to exist.
Photons Have No Mass Yet Are Affected by Gravity
- Light has no mass but its path still bends from the gravitational pull of large objects like the Sun.
The Big Bang Violated Known Laws of Physics
- All our known laws of physics break down right at the beginning of the universe during the Big Bang.
🧬 Your DNA is Remarkably Persistent
Our DNA preserves amazing historical details hidden within the double helix:
Mitochondrial DNA Can Trace Ancestry for Generations
- Mitochondrial DNA passes from mother to child relatively intact for over 200 generations.
Parts of Our DNA Originated Millions of Years Ago
- Around 8% of human DNA dates back to retroviruses that first inserted into primate genomes 30+ million years ago.
Fossil DNA Can Survive Hundreds of Thousands of Years
- Scientists have extracted DNA fragments from 450,000 year old hominids and even million year old bacteria.
🦴 The Human Body Has Some Surprising Features
Let’s explore some unexpected facts about our physical selves:
Your Bones Are Almost Always Wet
- Bone tissue has living cells with lots of moisture and blood vessels, apart from the center part called bone marrow.
Hair and Nails Don’t Have Their Own Blood Supply
- Once keratinized, the cells in hair and nails are dead and don’t require nutrients – they rely on root blood supply.
Your Body Hosts More Microbial Cells Than Human Cells
- Only 43% of the cells in your body are human – the rest are bacteria, viruses and fungi living on and inside you!
🧠 Your Mind Plays All Kinds of Tricks on You
Our brains don’t always portray reality accurately. Prepare to have your mind blown by these brain science facts:
Your Brain Fills in Your Blind Spot
- The visual cortex compensates for the blind spot caused by the optic disc to create a seamless image.
Memories Can Be Distorted Every Time They Are Recalled
- Reactivating memories makes them malleable, allowing small changes to accumulate each time we remember events.
Cognitive Biases Influence Our Thinking and Beliefs
- Hundreds of faulty reasoning shortcuts shape our thoughts, memories and perceptions without us realizing it.
🌱 Nature Has Developed Clever Solutions
Through evolution, organisms have adapted some ingenious tricks to aid their survival:
Shark Skin Effectively Kills Bacteria
- Dermal denticles on shark skin disrupt bacterial cell walls through micro-abrasions, stopping 99.9% of growth.
Coral Polyps Build Reefs Detectable From Space
- Tiny coral polyps can sense sunlight and construct massive reef ecosystems viewable by satellites.
Butterflies Drink Turtle Tears for Sodium and Minerals
- Butterflies land on turtles to drink the sodium and mineral-rich fluid from their eyes.
🤔 Some Natural Events Are Still Unexplained
For all our scientific progress, some mysterious natural phenomena still defy explanation:
Ball Lightning Can Last Over 5 Minutes
- Sightings report light floating balls during storms persisting far longer than expected for normal electrical discharge.
No One Knows What Triggers Solar Magnetic Pole Flips
- Every 11 years the Sun’s magnetic North and South poles flip, with immense implications, but we don’t know what initiates it.
There are Still Unsolved Cases of Spontaneous Human Combustion
- Numerous unexplained cases exist of humans suddenly bursting into flames without external ignition sources.
💊 Medical Mysteries Still Baffle Doctors
Medicine still contains many conundrums and unexpected effects. Consider these facts:
Placebos Work Even When You Know They Are Placebos
- Placebos yield measurable changes like pain relief and anxiety reduction even when people know they took a dummy pill.
###Laughing Gas is Also an Anesthetic
- Nitrous oxide puts you in a euphoric, dissociated trance state while also working as an analgesic.
Yawning Cools the Brain and Increases Alertness
- Yawning cools excessive brain heat while taking in more oxygen, making you more alert.
