Next-generation LHC: CERN lays out plans for €21-billion super-collider

CERN has unveiled its bold dream to build a new accelerator nearly four times as long as its 27-kilometer Large Hadron Collider—currently the world's largest—and up to six times more powerful.

The European particle physics laboratory, outside Geneva, Switzerland, outlined the plan in a technical report on 15 January.

The document offers several preliminary designs for a Future Circular Collider (FCC)—which would be the most powerful particle-smasher ever built—with different types of colliders ranging in cost from around €9 billion (US$10.2 billion) to €21 billion. It is the lab's opening bid in a priority-setting process over the next two years, called the European Strategy Update for Particle Physics, and it will affect the field's future well into the second half of the century.

[...] Not everyone is convinced the super collider is a good investment. "There is no reason to think that there should be new physics in the energy regime that such a collider would reach," says Sabine Hossenfelder, a theoretical physics at Frankfurt Institute for Advanced Studies in Germany. "That's the nightmare that everyone has on their mind but doesn't want to speak about."

Hossenfelder says that the large sums involved might be better spent on other types of huge facilities. For example, she says that placing a major radio telescope on the far side of the Moon, or a gravitational-wave detector in orbit, would be safer bets in terms of their return on science.

    If two trains are traveling towards each other at near the speed of light isnt their relative velocity ~2c?

    The answer is no, and for the same reason your far away galaxies moving really fast relative to earth is not an issue.

    Also, the only one bringing up religion is you. You think Ptolemy cared about christianity? I can care less about it other than it seems to somewhat defend against a majority of people treating their political party or government like the ultimate authority on everything.

    for the same reason your far away galaxies moving really fast relative to earth is not an issue.

    What is that reason? There is no 2x the speed of light? Therefore: . . . what?

    Also, the only one bringing up religion is you.

    Oh, come now! But not in my mouth. Religion is what all these wacko theories are about. Why, for instance, would it be important, or even relevant, to make an argument for the Earth being the center of the Universe, unless you perhaps believed that the purpose of the creation of the Universe was to create this one insignificant planet, and grow some sort of self-conscious slime [They're Made out of Meat" [youtube.com]] that could conceive of itself as the sole purpose of a vast and expanding universe.

    So again, it is the irrational forces that try to deny science, deny things like global warming and the insanity of Donald J. Trump. And history proves them wrong, as you will be proven wrong. Galaxies cannot exceed the speed of light, nor can the light from the galaxies exceed the speed of light. You need to reconsider your entire position, and perhaps update your life insurance. Or perhaps you are like the Orphelai? Or the Wedilai, only part meat? No brain, eh? Oh, there's a brain alright, but it's made of meat.

      For some reason, I assumed you were familiar with the basic concepts behind modern physics: https://www.physicsforums.com/threads/if-two-trains-traveling-at-0-5c-collide-head-on.486045/ [physicsforums.com]

        Not me, the geocentrists. And "two-trains" is more "trolley-car" science. Can you say something about dark matter, instead?
