Astrophysics: A message from the dark side
Yousaf M. Butt1
Abstract
Both astrophysicists and particle physicists are in on the hunt for the elusive dark matter that is thought to pervade the Universe. A high-altitude balloon-borne experiment offers the latest hints as to what it could be.
Humiliating as it may sound, you, me and everything we see — the Earth, Moon, Sun and stars — may be little more than cosmic contamination. Most of the 'stuff' in the Universe is thought to be in the form of invisible and elusive particles of dark matter.
- Yousaf M. Butt is at the National Academy of Sciences, Washington DC, on leave from the Harvard-Smithsonian Center for Astrophysics, 60 Garden Street, Cambridge, Massachusetts 02138, USA.
