RobinMcGroyne November 27, 2015 12:32 PM Never happen. It has very little immediate military value, so they won't do it. It also doesn't really require the theft of highly classified technology, so there's no fun in it. Oh, and it would make the Three Gorges dam look like putting in a sidewalk as far as expense goes. Never happen. Timelord November 27, 2015 02:28 PM Noooo! China will make the mini black hole that the LHC couldn't. They'll destroy the Earth! We're all doomed! Doomed!!! Douglas Bennett Rogers November 27, 2015 04:10 PM China has its own major fusion experiment so this will probably go ahead as well. The purpose is national promotion. Nairda November 27, 2015 10:10 PM The ambition of China is amazing. On the one hand, national promotion, yes. But their focus on advancing technology clearly highlights some science and engineering advisors are in at the top. Rkt9 November 28, 2015 12:26 AM Really? A port city that will likely be under the ocean by 2040. Shouldn't we figure out how to save and preserve our planet, before figuring out what happened just after the big bang? Richard D. McDowell November 28, 2015 03:29 AM There was to be an even bigger one in Texas buy the NIMBYs killed it.China does not have that pesky problem. SalvatoreAversa November 28, 2015 11:46 AM Look. I'm all for people trying to out-science each other -- but if China can't make a $2 screw that doesn't snap in half, or a car that doesn't crumple at 5 mph...what the hell is this thing going to do! Fretting Freddy the Ferret pressing the Fret November 28, 2015 02:08 PM Building these things raise national prestige, like erecting very tall skyscrapers, or endeavouring on space projects that no nation has attempted before. MarkPinnick November 28, 2015 04:28 PM To you so called scientists messing with something that is way over your heads. Something's are meant to be left alone ! Who's going to pat you on the back when you destroy the universe ? You are screwing with mother nature and shes going to get tired of us and sweep us off her planet .If your so intelligent then wise up before it's too late ! Cuckoo November 29, 2015 06:25 AM Didn't I read somewhere in these very pages that there's a new laser technology being developed that would make large particle colliders obsolete?This could be a very expensive white elephant.
