Dark matter is hypothesized to outweigh "ordinary matter" in the universe by a factor of five. That means all the stuff we ...

Neutrinos are fundamental particles characterized by no electric charge and very small masses, which are known to interact ...

In some models, dark matter is so basic that it can’t decay into anything else, even given exceptionally long timescales. In other words, it will essentially last forever.

In other words, to understand how a dark matter particle might affect a typical atom, we must consider the small interactions among the atoms arranged in a crystal lattice inside a material.

The first evidence that dark matter existed is traced back to the 1930s, but it became even more clear that some invisible mass was acting on the gravitational forces of the universe in the 1960s ...

WIMPs seemed like a good idea, as they could both explain the dark matter problem and bring us to a new understanding of fundamental physics. The idea is that we are swimming in an invisible sea ...

Can one vanishing particle shatter string theory — and explain dark matter? Penn physicists and collaborators at Arizona State University "test" the fallibility of a framework that seeks to ...

It makes intuitive sense that dark matter (accounting for 95% of the universe today) must have played a part in the Big Bang that kickstarted the existence of our cosmos, but supporting that with ...

Dark matter has turned out to be more elusive than physicists had hoped By Tracy R. Slatyer & Tim M. P. Tait edited by Clara Moskowitz Olena Shmahalo September 2024 Issue ...
