A sense of scale


I've been feeling overwhelmed by the scale of the planet, and its not just the sight of O'Docker's yacht in the midst of the wide seas.

I've been walking the streets of London imagining raging waters the height of three story buildings blast everything in it's path, racing up the Thames swallowing bridges and house boats with ease.

Then there's the picture above. It's a famous one, called the pale blue dot. And that one pixel is us; it's Earth.

In fact we are not even a single pixel, maybe 0.12 of a pixel. At this scale even if the whole of Japan has been shifted 2.4 m (a mind blowing concept) it would be invisible.

But what is even more amazing is that we can engineer a craft to travel 6 billion km away, command it to turn round, take a picture, then radio it back to us - and then be alive and conscious, able to wonder at it.

We might be tiny compared to the world, but as they say: size isn't everything.
