Why the LHC May Mean the End of Experimental Particle Physics
StartsWithABang writes: At the end of the 19th century, Lord Kelvin famously said, "There is nothing new to be discovered in physics now. All that remains is more and more precise measurement." He was talking about how Newtonian gravity and Maxwell's electromagnetism seemed to account for all the known phenomena in the Universe. Of course, nuclear physics, quantum mechanics, general relativity and more made that prediction look silly in hindsight. But in the 21st century, the physics of the Standard Model describes our Universe so well that there truly may be nothing else new to find not only at the LHC, but at any high-energy particle collider we could build here on Earth. If there are no new particles found below about 2–3 TeV in energy—particles that the LHC should detect if they’re present—it’s a reasonable assumption that there might not be anything new to find until energy scales of 100,000,000 TeV or more. And even if we build a particle accelerator to the fullest capacity of our technology around the equator of the Earth, we still couldn’t reach those energies.Read more of this story at Slashdot.
