the neighboring galaxies would have disappeared beyond the edge of the visible universe. After that, the universe would start to cool, and everything in it would freeze to death. Thankfully, that’s likely to happen hundreds of billions of years in the future, so there’s no need to buy a thick coat just yet, but it’s worth remembering the next time you feel the need to complain about the cold.
The LHC would probably be able to help scientists to better understand all of this, as well as provide evidence of other really fascinating stuff like extra dimensions, which as everyone knows are filled with monsters and aliens and big spaceships with laser cannons and …
Well, you get the picture.
At this point, it’s a good idea to mention the Might-Cause-the-Destruction-of-the-Earth-and-the-End-of-Life-As-We-Know-It issue. It’s a minor thing, but you can’t be too careful.
Basically, while the LHC was being built, and lots of men in white coats were chatting about dark matter and high-speed collisions, someone suggested the collider might create a black hole that would swallow the Earth. Or, instead, it could cause particles of matter so strange that they’re called “strangelets” to appear and turn the Earth into a lump of dead gray stuff. It’s safe to say that this chap wasn’t invited to the scientists’ Christmas party.
Now you or I, if told we were about to do something that might, just might, bring about the end of the world, wouldprobably pause for a moment and wonder if it was a good idea after all. Scientists, though, are not like you or me. Instead, the scientists pointed out that there was only a very, very small chance that the collider might bring about the end of all life on Earth. Hardly worth bothering about at all, really, they said. Not to worry. Take a look at this big spinning thing. Isn’t it pretty? 4
All of which brings us back to the important things happening in the Large Hadron Collider. The experiments were being monitored by a machine called VELO. VELO detected all of the particles given off when the beams crashed. It could tell their position to within one two-hundredth of a millimeter, or one-tenth of the thickness of a human hair. It was all very exciting, although not exciting enough for two of the men who were responsible for watching the screens monitoring what was happening, so they were doing what men often do in such situations.
They were playing “Battleships.”
“B four,” said Victor, who was German and blessed with lots of hair that he wore in a ponytail, with some left over for his chin and upper lip.
“Miss,” said Ed, who was British and blessed with hardly any hair at all, and certainly none that could be spared for his face. Nevertheless, Ed quite liked Victor, even if he felt Victor had been given some of the hair that should, by rights, have come his way.
Victor’s face creased in concentration. Somewhere in the not very vast vastness of Ed’s board lay a submarine, a destroyer, and an aircraft carrier, yet, for the life of him, Victor couldn’t seem to hit them. He wondered if Ed was lying about all those misses, then decided that Ed wasn’t the kind of person who lied about much at all. Ed wasn’t terribly imaginative and, in Victor’s experience, it was imaginative people who tended to lie. Lying required making stuff up, and only imaginative people were good at that. Victor had a little more imagination than Ed, and therefore lied more. Not much, but certainly a bit.
Ed heard Victor sniff loudly.
“Ugh!” said Victor. “Was that you?”
Now Ed smelled it too. There was a distinct whiff of rotten eggs in the room.
“No, it wasn’t me,” said Ed, somewhat offended.
For the second time in as many minutes, Victor wondered if Ed might be lying.
“Anyway,” said Ed, “it’s my turn. E three.”
“Miss.”
Beep.
“What was that?”
Victor didn’t look up. “I said it was a miss. That’s what it was: a miss.”
“No,”
