RE: A posthumous memo by Stephen Hawking: towards a super collider in China (or at CERN?)
Let me start by welcoming @lemouth back. Contrary to @gentleshaid opinion, I knew you weren't kidnapped 😁
Back to whether China should build the great Collider or not?. From the links you embedded in the post I discovered that the LHC CERN is not even up to 10years old. (10th Sept 2008). Why the hurry to quickly build another;I guess you physicists knows better , research work evolve daily. To build another one of 100km wide against CERN which is 27km is actually a welcome idea I believe. How ever, the question to be asked is if the Chinese guys are funding it, they will definitely put it on their own soil to prove to the world something I guess. Besides that, I think experience should be put into consideration, which should make CERN as the best location to be .
From another angle, will there be any seismic impact if two collider are placed within same geographical location?
I was not even really away ;)
It depends how you count. If you count from the first mention of it in 1986, it is kind of older ;)
This is at the end of the day politics... The targeted time is in any case in the post-LHC era.
At CERN, the LHC will play the role of a pre-accelerator (you can check this on the map). So, the two colliders will interact with each other, but on a controlled way. But no seismic impact, except maybe real earthquakes that won't probably hurt :)
Okay. Good
