I'm surprised it got through. $23B is a lot of money, and it will cost A LOT more when you start adding up the operational costs. In comparison, the space shuttle was $1.5B per launch "amortized" over 135 launches.

One of the effects of the Space Shuttle is that it hogged the budget of NASA (around 30%). Really worthwhile exploration and other space science programs got less funding because the Shuttle program was so big in cost.

Is the FCC going to do the same for Physics? There's an opportunity cost here that isn't getting addressed.

I mean I understand the need to keep pushing the boundaries of fundamental physics, but how long do you justify such spending on a single project? That same money could possibly be pumped…

Or 23 Billions for building the first serious AGI project!

I guess this might be a stupid question, but how does the size of the circle matter ? I mean, the particles are going in a round, wouldn't that be like infinite from the particles prespective, so is it related to the turn rate or something ?

The particles are steered round the accelerator with magnetic fields from superconducting magnets.

Higher speeds (and thus energies) can be achieved by increasing the circular circuit radius by limiting the force that has to be applied and the energy loss in the acceleration (change of direction around the circle).

Honest question, what are some engineering spin-offs that could come out of this? I'm asking because I'm reminded of a Peter Thiel interview where it's mentioned that, despite changing our view of the universe, no "real world" applications came out of the quark model discovered in the 1960s.

This is different from a project like ITER, which is also hugely expensive but could be a game changer.

$2 billion was sunk into this 40 TeV collider before it was cancelled https://en.wikipedia.org/wiki/Superconducting_Super_Collider

Canceled in part because of our $255 billion budget deficit, a number that seems quaint today.

Interesting, I just checked the number for ITER (i.e: Europe's main fusion project), the project has been estimated at around €20-30 billion (with some pessimistic estimates from the US at around €60 billion for the completion of the reactor). And that's considered a VERY HIGH cost and has been the main concern from participating countries. But somehow $23 billion for a new collider have been approved?

Edit: correction, $23 billion haven't been approved, the plans for a potential collider, estimated at $23 billion, have been approved.
