The Large Hadron collider will be used to smash particles together at never-before-seen energy levels.

The world's largest and most powerful particle collider is located in the Swiss countryside. After spending four years offline for improvements, the 17-mile loop was finally fired up today. With these fixes completed, scientists want to use the gigantic accelerator to smash protons together at record-breaking energies of up to 13.6 trillion electron volts.

The upgrade to the particle beams has done more than increase their energy range, it has made them denser with particles, which will increase the likelihood of a collision. Physicists' understanding of how the basic building blocks of matter interact, called the Standard Model, was shored up by the atom smasher during the two previous times it was there.

There is a particle from the dawn of time.

Scientists haven't found conclusive evidence of new particles or brand-new physics despite the thousands of scientific papers produced by the accelerator's experiments. They hope that will change after this upgrade.

"We will measure the strengths of the interactions with matter and force particles to unprecedented precision, and we will further our searches for Higgs boson decays to dark matter particles as well as searches for additional Higgs bosons," said Andreas Hoecker, a spokesman for the LHC.

protons zip around at near light-speed before slamming into each other What did the result look like? Particles can be new and exotic. The more energy they have, the quicker they go. The more energy they have, the bigger the particles they can make. The heavier particles are usually short-lived and break down into lighter particles when an atom smasher is used.

The Standard Model is a mathematical framework physicists use to describe all of the fundamental particles in the universe. Physicists are still looking for new ways to test the model, even though it has been around since the mid-1970s.

The model, which is the most comprehensive and accurate one so far, has enormous gaps, making it incapable of explaining where the force of gravity comes from, what dark matter is made up of, or why there is more matter than antimatter in the universe.

The new task of looking for particles that can persist across two colliders has led to the upgrade of the main detectors.

Physicists found a particle on a table.

There will be a 50-fold increase in the number of ALICE detector hits compared to previous runs. After smashing together, the atomic nuclei give electrical charge by the removal of electrons from their orbital shells, which creates a primordial soup called quark-gluon.

In addition to these research efforts, a bunch of smaller groups will probe at the roots of other physics mysteries with experiments that will study the insides of protons. The installation of two new detectors during the recent shutdown allowed for the addition of two new experiments, called FASER and SND. FASER will look for weakly interacting particles and SND will only look for weakly interacting particles.

Axion, a hypothetical particle that doesn't emit, absorb or reflect light, is a key suspect for what dark matter is made of.

Four years is how long the third run of the LHC is expected to last. After that time, the collider will be stopped once more for further upgrades that will push the power of the collider even higher. 10 times the data of the previous three runs combined will be captured by the High luminosity LHC once it is upgraded.
