Collaborate Disseminate
The remarkable thing about our universe is that it’s possible to explore at least some of its inner workings with very simple tools. Gravity is one example, to which [Galileo]’s …read more Continue reading Measuring Planck’s Constant with LEDs and a DMM
Astronomers have detected the highest-energy light ever seen, streaming in from near the center of the Milky Way. Hundreds of gamma ray signals were detected with ultra-high energies, with the most powerful signals crossing the Peta-electronvolt (PeV) … Continue reading Gamma rays 10 times more energetic than thought possible detected
Engineers at Stanford have created a new optical device that can easily manipulate light into basically any color desired. The system uses a series of modulators to fine-tune the frequencies of individual photons to change their color.Continue ReadingC… Continue reading Photonic device makes light any color by manipulating individual photons
Dark matter may make up the vast majority of the matter in the universe, but it’s strangely shy about making its presence known. Now, physicists have designed a new test to search for signs of two candidate particles, using the quirky world of quantum … Continue reading Quantum bits recruited to detect dark matter turning into light
OK, that was a little click-baity, but then again, so was the announcement this week that a scientist had confirmed Hawking radiation with a lab-grown black hole. It sure got our attention, at least.
As it turns out, the truth …read more
Physicists in Germany have measured the shortest timespan ever recorded. The team measured the time it takes for a photon of light to travel the length of a hydrogen molecule, and found it to occur in just trillionths of a billionth of a second.Continu… Continue reading Shortest event ever measured lasts mere sextillionths of a second
We’ve all seen recreations of the famous double-slit experiment, which showed that light can behave both as a wave and as a particle. Or rather, it’s likely that what we’ve seen is the results of the double-slit experiment, that barcode-looking pattern of light and dark stripes, accompanied by some handwaving …read more

Dark matter is a mysterious substance that seems to permeate the universe, but detecting it is tricky on account of it not interacting with regular matter very often. Scientists have a list of particles that they’re working through as possible suspects, and now that list is a little shorter. Experiments at CERN have ruled out some types of dark photons, inching us closer to finding the elusive dark matter.

Researchers at Delft University of Technology have created a detector that enables the detection of a single photon’s worth of radio frequency energy. The chip is only 10 mm square and the team plans to use it to explore the relationship of mass and gravity to quantum theory.
