Particle Physics
Nearly 100 years after being theorized, the strange behavior of the neutrino still mystifies us. They could be even stranger than we know.
Proposed over 2000 years ago by Democritus, the word atom literally means uncuttable. Revived in 1803, today's "atoms" can indeed be split.
Dust is ubiquitous in the modern Universe, appearing in nearly all galaxies. But our cosmos was born dust-free. So where does it originate?
The Holy Grail of physics is a Theory of Everything: where a single equation describes the whole Universe. But maybe there simply isn't one?
Across all wavelengths of light, the Sun is brighter than the Moon. Until we went to the highest energies and saw a gamma-ray surprise.
When you don't have enough clues to bring your detective story to a close, you should expect that your educated guesses will all be wrong.
Throughout history, "free energy" has been a scammer's game, such as perpetual motion. But with zero-point energy, is it actually possible?
A next-generation collider is required for studying particle physics at the frontiers. Here's the fastest, cheapest way to get it done.
Amplifying the energy within a laser, over and over, won't get you an infinite amount of energy. There's a fundamental limit due to physics.
Whether you run the clock forward or backward, most of us expect the laws of physics to be the same. A 2012 experiment showed otherwise.
Will we build a successor collider to the LHC? Someday, we'll reach the true limit of what experiments can probe. But that won't be the end.
