a new insight into the very birth of our universe
and the energy of each proton has risen to
are fed into
as they're already approaching the limiting speed of light
at 1/3 the speed of light
become superconducting
to boost
by an electric field
by analogy, stage three of our rocket

clockwise, anti-clockwise (counter-clockwise)
colder than outer space
compressed bottle of hydrogen gas
containing proton beams travelling in opposite directions
culminating in
designed specifically to
enabling them to be accelerated
from the pulsed electric field
gas cylinder
gigaelectron volts (GeV)
has caused this to be likened to
how our universe evolves
hydrogen atoms
in order to maximize the intensity of the beam
in short
in the same way that you would push a child on a swing
instead
into the source chamber
it marks the beginning
it will be travelling
it's about to enter the booster stage of the rocket if you will
it's the debris from these collisions
large hadron collider
let's follow just follow two such proton packets
linear accelerator
magnetic force
magnets exert a force on the passing protons at right angles to their direction of motion
one for each of the booster's rings
particle accelerator
particle tracks
positive charge
powerful computers
powerful electric magnets are used to bend the beam of protons around the circle
precisely controlled rate
protons
recombining the protons from the four rings, it's then flung into the Proton Synchrotron
similar to those following the big bang
soon the packets of protons will be energized sufficiently to be launched into the orbit
squeezes them closer together
straight acceleration is now impractical
synchronise incoming packets with those already circulating
teraelectron volts (TeV)
that is trapped in the detectors
the added energy manifests itself as increasing mass of the protons
the big bang
the booster is circular
the counter rotating beams cross over
the electrical field is now pulsed
the electrons are stripped off
the energy added to the protons by the pulsating electric field cannot translate into increased velocity
the energy of the collision is double that of the individual opposing protons
the four detector caverns
the lumbering first stage of a rocket
the microscopic kinetic energy of each proton is measured in units called electron volts
the packet is divided into four
the packets of protons are now channeled into stage 4
the point of transition is reached
the protons can't go faster, so they get heavier
they are 25 times heavier than they are at rest
they are repeatedly circulated
this initial acceleration
trying to reach a certain point
ultra high energy collisions
ultra sophisticated kickers
vacuum pipes
what governs its behavior today
where they can be made to collide
will be analyzed by
End of the world?, the Large Hadron Collider (LHC)
