Physicists are quietly testing an audacious idea: that the mass of everything around us might not come from an invisible ...

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 ...

Dark matter is elusive, complex, and perhaps far more massive than we thought. A recent simulation of the early universe suggests that one of the most promising targets in the hunt for dark matter — a ...

Axions are today's most popular candidate for dark matter, and numerous experiments are trying to detect them in microwave cavities where the axion should rarely convert into an electromagnetic wave.

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 ...

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 ...

New research explores how gravitational waves from black hole systems could help scientists study dark matter, using improved models and future detectors like LISA ...

New findings suggest that ordinary sound has negative gravitational mass. This is an Inside Science story. (Inside Science) -- The sound of a sonic boom may produce about the same magnitude of ...

Matter / antimatter mass-to-energy conversion probably rates above cold fusion on the totem pole of energy pariahs. At the heart of any viable engine must be a method for combining matter and ...
