Physicists have set the most precise limit yet on the mass of dark matter, the mysterious and elusive stuff that is thought to make up 98 percent of all matter in the universe and nearly a quarter of ...
An astrophysicist has shown that gravity may be able to exist without mass, a theory that suggests dark matter may not be necessary to explain phenomena observed in our universe. Dark matter is a ...
One truly elegant hypothesis of physics is the "zero-energy universe" hypothesis. It proposes that the net sum of the energy in the universe perfectly equates to zero. According to the idea, if you ...

Is gravity itself the missing piece in the dark matter mystery?
About 85 percent of the matter in the universe is thought to be dark matter, yet there is still no confirmed direct detection of any dark matter particle. Ground-based detectors, space-based ...
CHICAGO (CBS) -- A powerful new particle accelerator that could be set up at Fermilab, a telescope to observe the oldest light in the universe, and research to learn more about mysteries such as dark ...
At the end of a lecture on astronomy, describing how the planets orbit the Sun, a little old lady at the back of the room stood up and said: "What you've told us is all rubbish. The world is really a ...
Physicists at Stanford University and SLAC have built a contraption they hope will detect dark matter, though exactly which theoretical particles they think they’ll find—hidden photons or little blips ...
