Ancient Puebla’s secret tunnels.

The Puebla tunnels are a system of tunnels under the Mexican city of Puebla. Long considered to be an just a legend,

They were rediscovered in 2015.

The underground tunnel system is beliveved to date back to 1531. It had been covered for decades, and the archeologist who unearthed the tunnel discovered antiques in the mud.

Today it operates as a museum that doubles as a citywide thoroughfare.

@BrianRoemmele Another marvel in stone, created by people with knowledge from nearly three or four centuries ago, now almost forgotten in this century.

[Brian Roemmele @BrianRoemmele]

It is nice to see new brilliant minds come to accept what some of us have known for decades.

There is clearly technology that far surpasses the current epoch.

After decades of researching this and being called a fool, I welcome the level headed folks that now know what so many knew.

Earth’s rotation captured from an incredible distance of 1.5 million kilometers. 🌍✨

This animation is made from images captured by the DSCOVR satellite, positioned at the L1 Lagrange point between Earth and the Sun. From there, DSCOVR continuously observes the sunlit side of our planet, offering a remarkable view of Earth as it slowly rotates through space.

These frames were captured recently, on July 16, giving us a stunning perspective of our constantly moving planet. 🌎🛰️

One of the songs that remind me of what the USA is to me, always has been this song.

Fanfare For The Common Man

Aaron Copeland

It is a song of hope and achievement.

Happy Birthday USA.

🚨 This Ancient Cave Looks Like It Was Built by the Future… Not the Past

Hidden deep inside the rocky hills of Barabar Hills lies something that shouldn’t exist… at least not in the 3rd century BCE. The mysterious Lomas Rishi Cave, believed to be created during the reign of Emperor Ashoka, looks less like an ancient shelter—and more like a structure from a lost advanced world.

From the outside, the cave stuns with a carved entrance that perfectly imitates wooden architecture… in solid granite. An elegant curved arch, detailed carvings of elephants, and precise symmetry—everything feels too refined for its time.

But step inside… and the real mystery begins.

The walls are so incredibly smooth and polished that they reflect light like a mirror. Not rough. Not weathered. But glass-like. Even today, with modern tools, achieving this level of finish on hard stone is extremely difficult. So how did ancient craftsmen do it over 2,000 years ago?

Stand in that silent chamber, and something feels… off. The sound echoes strangely. The air feels heavy. The surfaces are cold, perfect, almost unnatural. It doesn’t feel ancient—it feels engineered.

Was this truly just a meditation space… or something more?
A lost technique? A forgotten science? Or evidence that history knows less than we think?

One thing is certain:
This cave doesn’t just tell a story—it asks a question we still can’t answer.
