"...circumference of the LHC accelerator is 26 659 m, with a total of 9300 magnets inside."
"At full power, trillions of protons will race around the LHC accelerator ring 11 245 times a second, travelling at 99.99% the speed of light."
"When two beams of protons collide, they will generate temperatures more than 100 000 times hotter than the heart of the Sun"
"When the LHC begins operations, it will produce roughly 15 petabytes (15 million gigabytes) of data annually – enough to fill 100 000 DVDs a year!"
