Particle acelerators ho!

There's no earthly way of knowing / Which direction we are going / There's no knowing where we're rowing / Or which way the river's flowing / Is it raining? / Is it snowing? / Is a hurricane a-blowing? / Not a speck of light is showing / So the danger must be growing / Are the fires of hell a-glowing? / Is the grisly reaper mowing? / Yes, the danger must be growing / 'Cause the rowers keep on rowing / And they're certainly not showing / Any signs that they are slowing!
