      Hi arthur13,

      It’s not the supercollider that’s colder than space – it’s superconductors! (Actually, I don’t really know what temperature the supercollider is, but I’m guessing it’s quite hot.) In my experiments, they work at around 10 milliKelvin. That’s about 1 hundredth of a degree above absolute zero degrees. I explain a bit more about what absolute zero temperature means in another answer:

      Cheers,
