How is matter different from mass? These and other questions about the deepest levels of physics, answered inside.

The majority of our evidence for dark matter’s existence comes from observing visible (or baryonic) matter that does not ...

Because we haven't found anything yet, we've started to wonder if dark matter might be lighter or heavier than we thought.

Half-metals are unique magnetic compounds that have been attracting interest in the development of mass-storage technologies ... RIKEN Center for Emergent Matter Science (CEMS) has demonstrated ...

Read, for one, thinks it is only a matter of time before astronomers start turning up intermediete-mass black holes. "There is every chance of us finding one [an intermediate-mass black hole] soon ...

A teaspoonful of their matter would weigh as much on Earth as an elephant—5.5 tons. White dwarfs typically have a radius just .01 times that of our own sun, but their mass is about the same.

After decades of study, scientists sound genuinely optimistic about the possibility of detecting primordial black holes, which might explain dark matter.

Here in our online science lab you can find out more about states of matter and see what happens ... specific heat capacity of the substance, the mass and required temperature change.

These black holes have mass of a few tens of solar mass and ... consequences for primordial black holes and the nature of dark matter, which we will now discuss. As of now, we know that there ...
