These could serve as good examples of dark matter since they emit little to no light. What is dark energy? Along with dark matter, there’s a separate entity — making up even more of the mass ...

Dark matter is a real pain in the neck. The term dark matter itself refers to a hypothetical substance that seems to solely ...

Look at some of the properties of Dark matter: (1) It is absolutely permeable to matter i.e., it can pass through a dense body like the earth or the sun without the slightest interaction and ...

However, dark matter is harder to study than even that, because it does not come conveniently clumped into super-dense balls like stars and black holes -- that would be far too easy.Instead, the ...

Of all the sciences, physics is unique in that it can come to a broad consensus with math alone—very little tactile evidence required. Never has this been the case more than with dark matter ...

Dark matter could also explain certain optical illusions that astronomers see in the deep universe. For example, ...

In the early universe, primordial black holes could acquire a "dark charge," giving them an unnaturally long lifetime, new research suggests. This makes them an interesting candidate for dark matter.

The major thing we know about dark matter, and the whole reason for the invention of the idea, is what it does. It pulls on things, the way matter does.

An idea derived from string theory suggests that dark matter is hidden in an as-yet-unseen extra dimension. Scientists are racing to test the theory to see if it holds up.

Thus, dark matter's gravitational impact is extremely spread out and, it turns out, can only be observed when we look at the large-scale distribution of visible matter in the universe: ...
