We can model the motions of planets in the Solar System quite accurately using Newton's laws of physics. But in the early 1970s, scientists noticed that this didn't work for disk galaxies—stars at their outer edges, far from the gravitational force of all the matter at their center—were moving much faster than Newton's theory predicted.

Researchers have developed a new technique to better measure special "terahertz" light. This light travels in waves longer than the infrared light that is beyond what the human eye perceives. The new sampling technique preserves the correlations between position and time in a pulse of terahertz light. The technique allows researchers to measure the shape of terahertz "light bullets," focused flashes of light that are as wide as they are long. This helps researchers learn how they can use terahertz pulses to improve particle accelerators. Particle accelerators help scientists examine new materials, proteins, and even the building blocks of our universe, and improved accelerators would help advance industry, medicine, and scientific research.
