That's the way it should sound, if it ever reaches it's purpose, like a sonic boom.
And if I don't mention the way it should look, it is because it will shed only shadow.
There is this big spiral-shaped tunnel rooted in Switzerland's underground. Everybody knows it is there.
Why, then, should it be kept underground? Well, simply put, because not everybody knows its dangers.
Sure we have been told about the risk, but we are curious (within science) as cats. Sure we have seen what it does outside, but we are loyal (within science) as dogs. Sure we have been told about pros and cons, but we are hungry (within and without science) as killer whales.
When they finally reach it, their purpose, when they finally find God's particle, their purpose, when they finally know that all their assumptions were true, their purpose, we will be gone (or going).
But there is light at the end of the tunnel: If they don't find God, they will surely had found the best way to misspend billions of dollars.
