Interesting Fact - Speed of Light

Scientists have been measuring the speed of light for three centuries, and they have it down to an accuracy of half a foot per second. The speed of light is 186, 282.3959 miles per second.

Which reminds me of the Monty Python song:-

Whenever life gets you down Mrs Brown,
And things seem hard or tough.
And people are stupid, obnoxious, or daft,
And you feel that you've had quite enough...

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 whizz.
As fast as it can go, 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.
