Sometimes I get a bit blue, thinking how insignificant we as a species really are. We’re on an insignificant rock, circling an insignificant star at a mean average distance of 93 million miles - in cosmological terms, an insignificant distance.

But let’s put that into human terms for a moment.

If we take the average distance from the Earth to the Sun, 93 million miles, and use that to calculate the circumference of our orbit of the Sun, we get (C=πd, or C=2πr ), or just over 584 million miles. That is a not-inconsiderable sum. Let’s put it into even sharper perspective, shall we?

Every year of your life, you are travelling nearly 585,000,000 miles. Impressive? Maybe, but a bit abstract still.

Every DAY of your life, you are travelling nearly 1.6 *MILLION* miles. Now I’m impressed. But wait, there’s more...

Every HOUR of your life, you are travelling nearly 67,000 miles. Think about that: You are, just by sitting where you are, speeding through the vastness of the universe at nearly 70,000 miles per hour. You are, simply speaking, travelling aboard the most magnificent spaceship ever imagined - why, it’s the size of a planet - because it IS a planet.

In my lifetime, my planetary spaceship has brought me more than 28 and a half BILLION miles.

I find that to be significant.

Probably rather than humans making their lives in space it'll be our artificial intelligence robotic descendants.
