Researchers detected gravitational waves—ripples in space-time—emanating from a cataclysmic event around 900 million light years away.
Dark matter is mysterious substance that appears to make up about 27 percent of the universe's mass.
IceCube searches for neutrinos—invisible, nearly massless subatomic particles which rarely ever interact with normal matter.
There are three different physical processes responsible for accelerating particles to vast speeds.
The discovery alone will not be sufficient to fill this gap, but it is an essential puzzle piece in the understanding of the interactions of fundamental particles.
The proposed accelerator will reside in an underground tunnel with a circumference of 62 miles. This is significantly bigger than the 17-mile structure that houses the Large Hadron Collider (LHC)—the current largest and most powerful accelerator in the world.
The findings have significant implications for the field of physics.
The search is on for an elusive particle that could shine a light on the "dark sector"—the vast majority of the universe that we cannot see.
Scientists at CERN observed Higgs boson decaying into subatomic particles called bottom quarks.
Particle accelerators speed up elementary bits of matter to probe fundamental questions in physics, however, current facilities require huge amounts of space.
The object can make about 60 billion rotations per second.
The detection of a single neutrino has opened up a whole new branch of astronomy.
The matter will be cooled to just above absolute zero, or minus 459.67 degrees Fahrenheit.
The research—which was led by the Institute of Photonic Sciences in Barcelona—was conducted by an international team of physicists from 12 institutions who managed to close a loophole found in a common test of quantum mechanics.
Antimatter and matter should have completely annihilated each other in the Big Bang, leaving nothing but energy.
"We've been looking for this since the 1970s."
The researchers believe the method could work for not just light, but other kinds of waves such as sound.
Neutrinos and gamma rays may be the "daughter particles" of ultra-high-energy cosmic rays.
If you pull it, it moves away. If you push it, it accelerates toward you.
Klystrons are powerful generators for creating the electromagnetic fields that accelerate particles within atom smashers.
