Especially “note the soccer pitch for scale”, which has not been drawn to scale, it's blown up by a considerable margin! That machine is HUGE!

UPDATE/EDIT: The "socker pitch for scale" might be the 2 pixel wide small dot, almost indistinguishable from the beginning of the curved arrow pointing towards the blown-up version of the soccker pitch. One can hardly see it in the zoomed version of the image, with a little bit of imagination.

(ILC overall length: 31km, 724 pixel. Socker pitch: 80 pixel, 31km / 724px * 80px = 3.42 km; a vector drawing corresponding to the screenshot can be found in the technical design report, Volume 1, §3.1.1, fig. 3.1)

I was going to complain too. If you zoom in, you can see "Length = 310 fields", although the text is still hard to read.

You can tell the graphic's written by someone not from the US, since their layman's measurement is a soccer field, not a football field.

There'll probably soon be confused replies to this comment from Europeans: "But that is a football field!"

As to why we have two games,

(a) A game where you occasionally kick the ball, but mostly you toss the ball and carry it around,

(b) A game where you occasionally hit the ball with your head, knee or chest, but mostly kick the ball around, and touching the ball with your hands is not allowed,

Why (a) is called "football," and (b) is not, I don't know. Historical accident, maybe?

Sports is definitely not my strong point. I would probably have been better at gym class if it'd been about things like the etymology of the word "football" and the history of the sport, but alas, these facts were lacking from my formal education and aren't important enough for me to Google.

Historically, football was closer to (a)

"By some accounts, any means could be used to move the ball to a goal, as long as it did not lead to manslaughter or murder."

I've seen a suggestion to disambiguate by referring to the American game as "handegg".

Here in Spain B is called Football and A is called American Football or Rugby

The word "Soccer" comes from "Association football".

Here's a map showing the proposed linear collider superimposed on a map of the Palo Alto / Redwood City area, with the correct linear scale:

At point "A" you can see the current Stanford Linear Accelerator complex for comparison. At 2 miles (3.2 km) in length, SLAC is currently the longest linear accelerator in the world. The ILC would be nearly 10 times the length.

For further comparison, the main accelerator ring at CERN is 27 km in circumference, and the arms of LIGO are each 4 km in length.

Lol an island per-disposed to earth quacks to host the most advanced particle collider built yet. There batter be are very good reason for this. That is worth the risk. Otherwise try Romania it's practically abandoned these days with all the citizens leaving to work in west europe.

The currently-largest linear accelerator (SLAC) is located right next to the San Andreas fault in earthquake-prone California.

So because it worked before and we didn't have any problems we should do it again without considering the risks?
