How big is the universe compared with a grain of sand? - video

'You'll never get your head around how big the universe is,' warns astronomer Pete Edwards of the University of Durham in this film about measuring astronomical distances. 'There are as many stars in the universe as there are grains of sand on the Earth.' So how far is a light year? And supposing our galaxy were the size of a grain of sand, how big would the universe be?

1. "The Universe is big. It's really, really big"

To me, the inability for humans to grasp just how large the Universe really is, and how small and insignificant that makes us, is the barrier to shedding our superstitions and evolving our consciousness. YMMV

Great video. Thanks for posting.

4. Let me get out my total perspective vortex.

The ol' TPV as we in the trade call it. Lucky I didn't eat that last piece of fairy cake last night.

2. Very cool

It's amazing & mind blowing when you think about how our planet came to be in such a vast universe.

5. A tribute

Galaxy Song Lyrics
Artist: Monty Python

Just remember that you're standing on a planet that's evolving
And revolving at nine hundred miles an hour,
That's orbiting at nineteen miles a second, so it's reckoned,
A sun that is the source of all our power.
The sun and you and me and all the stars that we can see
Are moving at a million miles a day
In an outer spiral arm, at forty thousand miles an hour,
Of the galaxy we call the 'Milky Way'.
Our galaxy itself contains a hundred billion stars.
It's a hundred thousand light years side to side.
It bulges in the middle, sixteen thousand light years thick,
But out by us, it's just three thousand light years wide.
We're thirty thousand light years from galactic central point.
We go 'round every two hundred million years,
And our galaxy is only one of millions of billions
In this amazing and expanding universe.

The universe itself keeps on expanding and expanding
In all of the directions it can whiz
As fast as it can go, at the speed of light, you know,
Twelve million miles a minute, and that's the fastest speed there is.
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth,
And pray that there's intelligent life somewhere up in space,
'Cause there's bugger all down here on Earth.
