On Wednesday, the biggest, most expensive scientific experiment in history, the gigantic $8.6 billion-plus atom-smasher - the Large Hadron Collider - will be switched on, and that might, claim a few deeply consternated scientists, be the end of the Earth, the Moon and the Sun, either in an instant, or over a period of a few months, during which time we could enjoy a long goodbye with the whole of humanity.
A lawsuit lodged at the European Court For Human Rights by the small group of extremely alert and alarmed scientists argues that if the LHC destroys the universe, it would "violate the right to life and right to private family life".
"In the first scenario, there is little warning.
For maybe a month, there would be no sign that life was about to come to an abrupt and nasty end for us all.
Then, earthquakes would start unexpectedly, alerting geologists to something terribly and unimaginably amiss.
After a few days, the seismic disturbances would reach catastrophic proportions.
Cities would be leveled and swollen oceans, in a series of mega-tsunamis, would slam into the continents' coasts.
The fact that the earthquakes were striking randomly, instead of along well-known geological fault lines, would be proof something devastating was afoot.
Finally, the end would come, in a disaster of Biblical proportions.
Earth would start to crack up; molten lava would wash over the land and the seas would start to boil; mega-hurricanes and cyclones would level buildings and forests; eventually, mountains would crumble as Earth's crust continued to disintegrate.
The fabric of the planet would start to disappear, trillions of tonnes of rock, water, air and life sucked into a whirlpool of unimaginable force.
From space, our blue-and-white home would appear to vanish down a plughole in a flash.
At least in that scenario we would have a little time, perhaps, to come to terms with the end.
But a second doomsday scenario is even more terrifying, with no warning.
In an instant - about 1/20th of a second - Earth would simply vanish from space.
Less than two seconds later, the moon would follow.
Eight minutes later, the sun would be ripped apart, followed by the rest of the planets in the solar system and onwards, a wave of destruction caused by a rent in the fabric of space itself, spreading out from our world at the speed of light."
Err, indeedy, it would.
And winning said lawsuit would be a tad pyrrhic if the universe is all sucked asunder, or whatnot.
Anyhoo: good luck to you all! Love you heaps! You've been absolute treasures!
