Silly speculation, but imagine if the Large Hadron Collider opened a door to the spirit world, which would be considered another dimension. Perhaps the LHC will reveal demunz.
The quest is not without controversy: Scientists say there's a chance that the LHC could create microscopic black holes, a phenomenon never before observed on Earth. They hasten to add that the tiny singularities will instantly pop out of existence, but that hasn't stopped critics from trying to block the collider's startup. Two of the critics have filed suit in federal court in Hawaii, seeking the suspension of LHC operations until more studies are done.
Beyond the God ParticleWhat if physicists don't find the God Particle they are expecting to see? Ellis acknowledged that was a possibility. "This might be a little bit difficult to explain to our politicians, that here they gave us 10 billion of whatever, your favorite currency unit, and we didn't find the Higgs boson," he said.
But Ellis has faith that even then, there'd be something to discover — maybe something even weirder and more wonderful than the Higgs boson.
"Probably the most likely option then might be extra dimensions," Ellis said. "And there are some ideas where if you have some additional dimensions of space, you could somehow do the job that the Higgs does in the Standard Model."
For years, string theorists have noted that their equations come out better if they assume that the universe has nine or 10 spatial dimensions instead of the three we can perceive. The LHC could provide the first evidence of those extra dimensions: Some theorists say the collisions could produce anomalously heavy particles, suggesting that part of their momentum was going into the extradimensional realm. Harvard physicist Lisa Randall estimates that the LHC could nail down the evidence for extra dimensions in five years.
