Скачать или смотреть How big is the universe — infinite or finite?

The size of the universe is one of the greatest mysteries we’re still trying to solve. 🌌

🌀 *The Observable Universe:*

From Earth, we can only see as far as light has had time to travel since the Big Bang, about **13.8 billion years ago**.
Because space itself has been expanding, that distance is now around **46 billion light years in every direction**.
That makes the observable universe about **93 billion light years across**.

✨ *But what lies beyond what we can see?*

The universe could be *much larger* than the observable part—potentially *trillions of light years* across.
Many scientists suspect it might even be **infinite**, stretching on forever with no edge.

⚖️ *Finite vs. Infinite:*

If it’s **finite**, it may curve back on itself, like the surface of a sphere. You could, in theory, travel far enough and end up where you started.
If it’s **infinite**, then it has no end, and there could be endless galaxies, stars, and perhaps even copies of us out there.

🧩 *The Truth?*
We don’t yet know. Current telescopes can’t see beyond the observable horizon, and physics may never allow us to. But whether finite or infinite, the universe is far bigger than our minds can fully grasp.
