The Black Knight Satellite: Proof of Ancient Tech in Orbit?

Before Sputnik.
Before NASA.
Something was already up there… watching us.

In this deep-space episode of Buried Knowledge, we uncover the mystery of the Black Knight Satellite — a strange, dark object detected in Earth's orbit for over a century. Some call it ancient alien tech. Others say it’s a relic from a forgotten civilization.

It’s been photographed. Tracked. Denied.
But it never left.

What is it really doing up there?
Who put it there?
And why are they so afraid to talk about it?
