# Superconducting Super Collider still worth building after LHC?

The cancelled Superconducting Super Collider had 3x beam energy of 40TEV vs LHC 14TEV.
While it has been cancelled, could it be re-started 20-30 years after LHC hits diminishing returns in the future?

Is there any new expected physics in SSC range over and above LHC that would make it worth re-building in the 2030-2040 time frame?

Are there any circular colliders proposed after LHC and if so, what are its energies and what new physics are intended to explore?
Are there any new HEP physics in the 40 TEV range, i.e SUSY, technicolor, black holes, etc., that would be worthwhile over 14TEV, OR
do new HEP physics require an order of magnitude more energy (i.e 400TEV) to build and explore?

Hopefully 40 years into the future, the technology that made SSC prohibitively expensive in the 90s could be less expensive.

No, there is absolutely no point in developing the Superconducting Supercollider. With the recent completion of the LHC and the amount of money put into this project we will have high dependency on our future discoveries in the LHC for the next ten years. Even in the future public interest isn't devoted to Particle Physics and with the economy in the state it is in the United States has greater dilemmas to worry about than expanding the horizon of scientific research in Particle Physics. The only reasonable scientific expansion would be industrial in nature which would contribute to the economy: nanotechnology, energy research (fusion), and biotechnology.

I was thinking in the 2040-2050 time frame, and with future multinational funding. Is there important HEP physics in the 40TEV range?

Does HEP expect another circular collider this century or will it be after 2100?

At the last ICHEP, the french president addressed the participants in a press conference, and warned that using the current crisis to cut on fundamental research is a blunder.
ILC for $20 billion? 14. Aug 18, 2010 ### Kevin_Axion The Construction for the SSC exceeded$12 billion,and the SSC was being built during the late 1980s and early 1990s With the differential in cost for materials, land and labour in the 1980s and 1990s to the cost of these resources today, this is why the ILC appears so expensive.
