How Big Is the Universe? We May Never Know

#Cosmology #Universe #Astronomy
How big is the universe - and how much of it can we actually see?

The universe is around 13.8 billion years old, yet the observable universe is roughly 92 billion light-years across.

That sounds impossible at first. But the answer lies in the expansion of space itself.

In this documentary, we explore the observable universe, how we see back through cosmic time, why the universe is much larger than the distance light has travelled, and what might exist beyond our cosmic horizon.

We’ll look at the cosmic web - the enormous network of galaxies, clusters, filaments and voids that stretches across the observable universe - and the strange possibility that everything we can see may be only a tiny part of what actually exists.

The most honest answer is also the most fascinating - we don't know how big the entire universe really is.

It could extend unimaginably far beyond what we can observe. It could be finite without having an edge. Or it could even be infinite.

What we do know is that the observable universe is already almost incomprehensibly large.

So when you look into the night sky, you're not seeing the entire universe - you're seeing a window into it.
