Between Earth and the Moon lies a belt of radiation so lethal
that NASA's own scientists called it the greatest obstacle to deep space travel.
We supposedly crossed it in 1969.
In a spacecraft with aluminum walls thinner than a car door. 🧵
🚨 Two giant bubbles of energy are exploding out of the center of our own galaxy.
They’re called the Fermi Bubbles, each one stretching 25,000 light-years above and below the Milky Way.
We discovered them only in 2010.
We still don’t fully know what created them.
Our galaxy is not quiet.
It’s leaking violent energy into space and we only noticed recently.
🚨 There’s a region of space so empty it shouldn’t exist.
It’s called the Eridanus Supervoid, a cosmic hole roughly 1.8 billion light years across where almost nothing is found: no galaxies, no clusters, barely any matter.
It’s so extreme that some scientists once suggested it might be the imprint of another universe colliding with ours.
Most people have never even heard of it.
Yet it sits there, quietly challenging our entire model of how the universe should look.
Draw any 3 circles. Any size. Anywhere.
Now draw lines hugging each pair of circles from the outside.
Those 3 lines will always meet at exactly one point. Every. Single. Time.
No exceptions. No conditions.
It doesn't matter how you draw them.
This is Monge's Theorem. Proved in 1809.
Nobody knows why the universe insists on this. It just does.
Mathematics doesn't describe reality.
It reveals rules reality was already following before we existed to notice. ⚛️
The sun you see right now doesn't exist anymore.
You're seeing it as it was 8 minutes ago.
The Andromeda Galaxy?
2.5 million years ago.
The furthest object visible to the naked eye? You're seeing light that left before humans existed.
But here's the part nobody tells you:
There are galaxies so far away that the light they emitted the moment the universe was born, still hasn't reached us.
We will never see them.
Not because they're gone.
Because the space between us is expanding faster than light can cross it.
The observable universe isn't the universe. It's just the part that had enough time to say hello. 🌌
There is a place in the universe where time stops completely.
Not slows. Not pauses. Stops.
At the event horizon of a black hole, an outside observer watches you freeze in the last moment before you cross.
You never actually fall in.
You just redshift into eternity.
Dimming. Slowing. Frozen forever at the edge.
From your perspective?
You crossed instantly. Felt nothing.
Saw the entire future of the universe flash before you in a single moment.
Two observers. Same event.
Completely different realities.
Einstein called it relativity.
The universe calls it Tuesday. ⚛️
The people who hurt you the most
probably don't think about you at all.
You've replayed the conversation a thousand times.
Built arguments. Rehearsed responses.
Lost sleep.
They moved on the same day.
The prison was never them.
You built it. You maintain it.
You hold the key.
This is called the "Rumination Trap."
And 73% of people are stuck in it right now. 🧠
The universe shouldn't exist.
At the Big Bang, matter and antimatter
were created in equal amounts.
Equal amounts annihilate each other completely.
The math says the result should have been pure energy. Nothing else. No stars. No planets. No you.
But for every 1 billion antiparticles,
there were 1 billion and 1 particles of matter.
That single extra particle per billion
is every galaxy, every star, every atom
of everything that has ever existed.
You are the universe's rounding error.
And it's the most precise accident in existence. ⚛️
If you observe a quantum system
fast enough, it freezes.
Called the Quantum Zeno Effect.
A watched particle literally cannot decay. Observation doesn't just affect reality.
At quantum scale, it stops it. 👁️
A watched pot never boils.
Turns out that's not just a saying.
It's physics. ⚛️
The most powerful thing you can do
in a world designed to keep you reacting is nothing.
Stillness is psychological warfare.
Most people have no defense against someone who simply doesn't need to respond.
There is a size so small
that the concept of distance stops making sense.
0.000000000000000000000000000000000016 meters.
The Planck Length.
Below this, space itself breaks down.
Physics has no equations for what happens there.
The universe has a resolution limit.
Just like a pixelated image. 🌌
Light decides what it is
based on whether you're watching.
Shine it through two slits unobserved it goes through both simultaneously.
Watch it, it picks one.
The universe literally behaves differently
when it thinks no one is looking. 👁️
Physics says it's more probable
that you spontaneously appeared 5 seconds ago, complete with false memories, than that the universe has existed for 13.8 billion years.
It's called the Boltzmann Brain paradox.
Physicists hate it because they can't disprove it. 🧠
Quantum mechanics says there's a non-zero probability that you could walk into a wall and appear on the other side.
It's called quantum tunneling.
It's not science fiction. It's how your USB charger works.
The wall isn't as solid as you think.
Neither are you. ⚛️
@PhysInHistory Reminds me that the biggest breakthroughs started with someone sitting with the mystery instead of rushing to close it. Still the best advice for any scientist.
The Pillars of Creation are 6500 light years away.
The image we see today is 6500 years old. They were likely destroyed by a supernova 6000 years ago.
We are still watching them exist.
In reality, they are already gone. 🔭
