Troubled sleep since hearing about dark energy and the ever-expanding universe. How can I hope to keep up? I think we need some lighter matters to counteract all the dark matter. My most worrying thought was that the universe is actually within a games console. There are thousands of levels and whoever playing it is slowly improving. But there comes a point when it all collapses in on itself and the player has to start again. The big bang is just a re-boot. Maybe this is the highest level that has ever been achieved – in the history of the universe! I fear I have just missed out on this year’s Nobel prize. A quick “share” to the committee’s Facebook page should secure it for me next year.
