Unifying all the forces and particles would require a particle accelerator far more powerful than humans have ever built.
Don Lincoln, senior scientist at Fermi National Accelerator Laboratory and adjunct professor of physics at the University of Notre Dame, conducts his research using the Compact Muon Solenoid detector located at the Large Hadron Collider. His scientific interest is broad, spanning such questions as the nature of dark matter, understanding why we see no antimatter in the universe and whether the familiar quarks and leptons are composed of even smaller particles. In addition to his contributions to Space.com and Live Science (http://www.livescience.com/topics/expert-voices-don-lincoln/), you can follow him on Facebook at http://www.facebook.com/Dr.Don.Lincoln.
An international group of physicists has announced that they have seen the first signals in a cube-shaped detector called ProtoDUNE.
Ten years ago, the world's largest scientific instrument was turned on and the start of a research dynasty began.
The history behind the discovery is a fascinating tale with twist and turns that would make Agatha Christie's head spin.
The g-2 experiment has begun and it has the potential to shake up the reigning model of particle physics.
A new night-sky survey of distant galaxies suggests that dark matter is less "lumpy" than previously thought.
While many people take the existence of dark matter for granted, it's still a theory that has yet to be proven. But new evidence could bolster support for dark matter theories.
There's a concrete reason enormous particle accelerator experiments won't spawn black holes and end the world.
