I have no idea.
We have no idea.
When radio waves were discovered, they weren't called radio waves, because there were no radios. They were discovered as some sort of radiation.
Basic science for big breakthroughs needs to occur at a level where you're not asking, "What is the economic gain?" You're asking, "What do we not know, and where can we make progress?"
So what is the LHC good for? Could be nothing other than just understanding everything.
