science – luna's on line

Take a last look at the world we call Home. You’ll never see it again. After this generation, and maybe the next, nobody will. It won’t exist.

And we, brave comrades, will not see our next home, nor the several generations which will succeed us. Our new home is far, far too distant. Almost too distant to contemplate. It lies beyond our own planetary system, beyond anything visible to our eyes. Only our most powerful telescopes can see; reached only by a single exploratory probe which has travelled over many of our lifetimes.

Thus our new home has been identified. All available data indicates it is suitable for life. Or was. Remember we are travelling such a very great distance across the galaxy, that what we know about this planet is only its past.

But we are optimistic. No other race could have been so stupid. No other beings would wantonly destroy their planet.

So, brave comrades, we boldly go, across to the westward arm of the great spiral galaxy, to a group of eight planets which orbit a sun, just like ours. Our destination is the third from that sun, a blue planet, and we will call it Home.

Everyone fled for the old, deserted places; to the caves, the ruins and the ancient abandoned settlements. The cities had long gone; collapsed in on themselves. All modern infrastructure wiped out.

No-one understood why, but there was no longer anyone to ask or to explain. The politicians, the scientists and the specialists had long retreated into their state-of-the-art doomsday bunkers. Much good would it have done them. All technology had fried when the black hole came into view.

The inevitable came, although it took months. Quite a number of us survived. There had been long enough to prepare. But then the time came. The skies grew dark. There were flashing lights, the rushing of wind, a strange hollow feeling that seemed to gnaw on the soul.

When it was all over, we awoke to a bright new dawn. We opened our eyes, felt our limbs, went outside and looked at each other. Then we noticed. Everything was reversed like in a mirror. Our hearts were beating on the other side of our chests. It took a little getting used to.

We carried on, improvised. Crops grew. The water in our wells was sweet. Everyone felt good, younger by the day. We were more vigorous, more robust, we were quicker and stronger. And then we realised. We were actually getting younger, day by day. And the process was speeding up. What would become of us as we hastened to youth, to childhood and earlier?

Where were you before you were born?

Don’t have nightmares, it’s a long, long way off:
