Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter ...
This article explores how our understanding of the universe has evolved—from the scale of everyday experience down to the ...
Superheavy charged gravitinos may be the long-sought answer to dark matter. Dark Matter remains one of the biggest mysteries ...
In particle physics, data long outlives the detectors that generate it. A decade ago the 4,100-metric-ton Collider Detector at Fermilab (CDF) reached the end of its life and was shut down, stripped of ...
Determining the nature of dark matter, the invisible substance that makes up most of the mass in our universe, is one of the ...
