It depends on which accelerator we're talking about, but let's consider the . ...It's minus 271 degrees. ...This is a picture of one of the 15m long … - Suzie Sheehy

While a theoretical physicist's ideas must take into account the results of experiments, an experimental physicist has a more nuanced job. She is not simply testing out the ideas of theoretical physicists; she is asking her own questions and designing and physically building equipment she can use to test those ideas. ...[H]er practical knowledge ranges from to chemistry, from to .

[I]f we start creating things like mini black holes, which we may or may not, they will pop out of existence so quickly that they wouldn't have time to suck any matter in... [T]he interesting message that I take from this is that these machines are built so infrequently... 25-30 years between these big accelerators. Every time it happens, I'm told by my... retired colleagues... It happens every time, this scare story that we're going to destroy the earth with it, because it's so long between them that people actually forget the media hype that happened the last time around.

The only problem is [that] the accelerator for this is about 10 times more powerful... than we can currently make. So there's lots of challenges for people like me who design accelerators, to try and come up with ways of making them more and more powerful, for very good reason.
