Hydrogen may be the most common element in the cosmos, but scientists could use it to do something unique: uncover the nature of dark energy, the mysterious force driving the accelerating expansion of the universe.
This new line of dark energy investigation comes from the fact that researchers have determined that the CHIME (Canadian Hydrogen Intensity Mapping Experiment) project can detect the faint radio glow of hydrogen from the universe's distant past.
Not only does this represent a faster and much less expensive way to investigate dark energy, but it is a major milestone for CHIME. The instrument was specifically devised to investigate dark energy and its pervasive influence.
