Deep underground amidst the Alps, scientists are barely able to contain their excitement.
They whisper about discoveries that would radically alter our understanding of the Universe.
"I've been hunting for the fifth force for as long as I've been a particle physicist," says Dr Sam Harper. "Maybe this is the year".
For the past 20 years, Sam has been trying to find evidence of a fifth force of nature, with gravity, electromagnetism and two nuclear forces being the four that physicists already know about.
He's pinning his hopes on a major revamp of the Large Hadron Collider. It's the world's most advanced particle accelerator - a vast machine that smashes atoms together to break them apart and discover what is inside them.
It's been souped up even further in a three-year upgrade. Its instruments are more sensitive, allowing researchers to study the collision of particles from the inside of atoms in higher definition; its software has been enhanced so that it is able to take data at a rate of 30 million times each second; and its beams are narrower, which greatly increases the number of collisions.
Large Hardon LOL
It's difficult not to get over-excited.
