Yet another investigation, PICO, takes place in a bubble chamber, where dark matter interactions create bubbles – different from most radioactivity.

Dark matter has never been seen, but scientists think it could help explain our universe if ever detected. One Alberta researcher is trying to build a machine to detect it.

Dark matter, a type of matter that does not emit, absorb, or reflect light, is predicted to account for most of the ...

Is it possible that the universe’s most mysterious substance could finally leave a visible trace?” For decades, this question ...

Although dark matter is invisible, its various effects can still sometimes be seen—such as in this Hubble Space Telescope image of the galaxy cluster Abell 370 some four billion light-years from ...

Dark matter makes up around 85 per cent of the matter in the universe, but it does not emit or absorb light. While its gravitational effects are clear, scientists do not yet know what it is made of.

If this idea is correct, such "dark matter lampshades" could help solve the mystery of what dark matter is made of. This is a huge problem in science because, despite making up around 85% of the ...

Dark matter is one of nature's most confounding mysteries. It keeps particle physicists up at night and cosmologists glued to their supercomputer simulations. We know it's real because its mass ...

This week's question comes from Terry Pitt-Brooke, from Salmon Arm, British Columbia. He asks: What evidence for dark matter has been found in our galaxy? Sean Tulin, a professor of physics at ...

2012. There is no room in the model for a dark matter particle. The discovery of such a particle would open the door to new laws of physics and a deeper theory of matter.
