_SThe observable universe is
93,000,000,000 light years wide.
Not the full universe. Just the part where
light has had time to reach us.
Beyond that — we have no idea.
It could go on forever.
The nearest star to Earth after our own Sun is
Proxima Centauri — 4.24 light years away.
At the speed of our fastest
ever spacecraft, Voyager 1 — it would take
73,000 years to get there.
That is our closest neighbour in space.
The zoom you just watched
started at the outer edge of
everything humans have ever observed.
It ended at you.
And it still didn't show you how big it actually is.
👇 Did the size of the universe
ever cross your mind before this?
