#Love or chemical wildfire?

When you fall, your brain doesn’t whisper… it screams.

Dopamine, oxytocin, cortisol — the cocktail that changes everything.

I break it down (without killing the magic) → medium.com/@alexmediano...
This is what happens in your brain when love sets fire inside you.
This is what happens in your brain when love sets you on fire: a chemical storm that transforms your body, mind… and soul.

Some #blackholes just chill and snack on nearby matter.
Not this one.

This one got kicked out of its own #galaxy and is now racing through #space at over 4 million mph.

Behind it? A glowing 200,000-light-year trail of newborn #stars.
Cosmic heartbreak never looked so productive.

Cosmic explosion or a black hole sneezing?

What you're seeing is a #quasar — a #blackhole so hungry it outshines its entire #galaxy.

It devours #matter, compresses it, and then spits out jets of energy like it’s running late for something.

It’s just the #universe being dramatic again.

While everyone watches the wars on Earth, there’s another one unfolding silently above us.
The U.S., China, and Russia are already fighting for space — just without bullets.

Satellites, orbits, stations, signals: the new chessboard of power has no borders, only void.

Space Geopolitics: The Silent Conflict Between the U.S., China, and Russia
Space is no longer neutral. The U.S., China, and Russia are militarizing it — and private companies like SpaceX are part of the game.

Floating above a planet that never stops spinning, a human-made ship defies the void.
We are small, but not insignificant.

If one day we're imprisoned for downloading PDF books, I hope they separate us by literary genre.

🌍 There we are.
You, me, the memes, Mondays… all floating together on a tiny blue dot.
From up here, you can’t see borders, WiFi, or your to-do list. Just a small home, drifting in the middle of everything.

A place where not even light can escape and time gets weird?
No, it’s not your Monday morning — it’s a black hole.

Mysterious, terrifying, and — surprisingly — beautiful.
I wrote about them (not because I want to fall into one, I swear).

The universe has its own version of absolute silence.
It’s called a black hole.

Rome, 1633.

A telescope, an inconvenient truth, and a trial that would shape history.

Galileo didn’t just see the stars — he saw through power.

Galileo, the Church, and the Night Truth Couldn’t Be Silenced
One man. One instrument. And a truth so powerful, it defied centuries of belief.

This is not science fiction.
It is a bubble 7 light-years wide, sculpted by the breath of a dying star.
The universe doesn’t invent, it reveals.

What if we're not alone—but no one is talking?

I just published a piece exploring the Fermi Paradox:
why, in a universe full of stars and planets, no one seems to answer.

🪐 Let me know what you think: is silence proof… or a warning?
The Fermi Paradox: Are We Really Alone in the Universe?
Fermi’s Paradox questions why, despite billions of stars and planets, we haven’t found alien life. Are we truly alone in the vast cosmos?
