CERN’s proposed 100-km particle accelerator would run rings around the LHC

CERN, the European research organization responsible for operating the Large Hadron Collider (LHC), has released a report outlining a proposed particle accelerator that would be nearly four times as long and 10 times as powerful as its predecessor. Dubbed the Future Circular Collider (FCC) – for the time being at least – the LHC’s successor would cost around €9 billion (US$10.26 billion) and could be up and running by 2040.

2 Sydney Light Rail projects.

A bargain.

surely the king colossal collider is a better name than “future”, what will they call it once it has been built ¿

It’ll probably cause the long promised collapse of the Earth into a black hole, so not a problem.

Better not put it to a public poll.. might get Collider McColossal McColliderface

I wonder what year the 1000km collider will be built.

I’ve got a design for a bigger collider than that. I wonder where I put it. Can’t find it.
The overall layout was something like this.

Could you actually create a Earth killing black hole with a particle collider

Probably not, but it has been suggested that it might be possible by some serious scientists.

Given the consequences should it happen, I’m not convinced that their concerns were adequately addressed.

> Using one of the most powerful lasers in the world
Given that these lasers are of the order of 70 to 100 metres long, I wouldn’t exactly call it “tabletop”.

> 4.25 giga-electron volts
Too small by a factor of 3,000 compared to the LHC.

So if it scales linearly, 70 metres by 3,000 is 210 km just to get to the energy of the LHC. Bigger than even the proposed 100-km accelerator.

They should just build one round the Equator.

Too many mountains in the way. And some troublesome plate tectonics.

Next step up from an Australia-sized one would be to use the floor of the Pacific Ocean. Avoiding all the trenches and ridges.

Lay the beam pipe like you’d lay a communications cable.

Same circle, but easier to see the continents in this view.

Does it have to be a circle can it not just be a straight line

About a billion Sydney Light Rails I’d say.

the beam pipe is the easy bit. need all those superconducting magnets to guide the beam though.

though if you had a black hole in the centre you could use the photon sphere to guide the beam…
