How the Large Hadron Collider works Video Transcript
>> The Collider [assumed spelling] itself is a marvel of precision engineering. This animation shows how two beams of invisible hydrogen protons will be driven around the tunnel in opposite directions, inside ultra-high vacuum tubes, propelled and guided by super-conducting magnets, chilled with liquid helium to a temperature of minus 271 degrees Celsius, colder than deep space. As the two beams approach speeds of 186,000 miles per second they will smash into each other at four different parts of the Collider. At the heart of the machine are four massive detectors, where the actual collision of the sub-atomic particles takes place. This one is seven stories tall, nearly 8,000 tons of lead, steel, wires, plastic, and magnets to capture and record everything that's going on inside. So you can bring these -- I mean -- you can race these little --
>> Protons
>> protons around this 17 miles track at the speed of light, smash them in together in a beam that's the width of a hair. You could measure all that stuff and what happens in a billionth of a second?
>> Billionth of a second or 25 nanoseconds.
>> So let's set the scale.
>> Here to there is 25 feet. Turn my flashlight on -- by the time that beam reaches that wall is the time that we have to have recorded all this information. ^E00:01:28
