It provides independent, direct evidence for dark matter and supports the view that dark matter particles interact with each other only very weakly.

The dark matter (which interacts weakly) did not.

But lots of things weakly interact with the same light.

Because neutrinos interact weakly with matter, however, only one in a trillion is stopped on its way to Earth.

But these particles interact so weakly with other matter, which means they produce little energy and so remain invisible.

The rest of the dark matter is particles that interact weakly with other objects.

Others, classified as Wimp's, for weakly interacting massive particles, have been hypothesized, but remain undiscovered.

As a result it becomes much easier to produce particles such as neutrinos that interact only weakly with other matter.

In this case the inorganic component interact only weakly or not at all with the organic polymer; hence, a class I material is formed.

Linear alkanes interact weakly with the chromophores and crystallize when frozen.
