edit: My original post was waaaay too agro, I was way out of line. I misinterpreted your original post as meaning -the minimum size of a larger collider than the LHC would be larger than the Earth's radius-, instead of -a collider larger than the LHC that could hypothetically produce dark matter would be larger than the Earth's radius-. for posterity: That collider can't get to the energy levels needed because it doesn't exist. It doesn't exist because it's construction was cancelled after the project was defunded. Where it to have finished construction, it would accelerate protons up to 20 TeV. The LHC reaches 6.5 TeV. All of that information is clearly stated in the link I posted and is completely uncontroversial. Stop bullshitting.
