Hey @lemouth, thank you so much for your contributions, I've learned so much from your blogs.
The LHC is a true beast. Can't even imagine what next level machinery would perform like. By the way what does the term 'powerful' refer to in the case of circular colliders? I'm guessing it is somehow connected to the amounts of energy that can be produced.
Would be fun to see what the Chinese can do. One can expect a lot from their Engineers.
Is your beast more powerful? This should be demonstrated somehow... Let's switch on the magnets!
Unfortunately, we definitely need the rest of the world. For instance, the magnet technology is mostly American. Having the workforce is here not sufficient, which is why the scale of such a project would be the world :)
