hot dark matter

What they might manage with hot dark matter is not clear.

Other origins for the structure might be as well or better served by hot dark matter.

An example of hot dark matter is already known: the neutrino.

The best candidate for the identity of hot dark matter is the neutrino.

And it was the reverse for hot dark matter.

Hot dark matter cannot explain how individual galaxies formed from the big bang.

Some scientists favored hot dark matter, particles that traveled close to the speed of light.

Hot dark matter works on the small scale.

Neutrinos, a form of the faster-moving hot dark matter, are everywhere.

Hot Dark matter has only one known form - neutrinos, although other forms are speculated to exist.

As that idea has run into trouble, scientists have revived the notion of hot dark matter, like the more energetic neutrinos.

Hot dark matter - particles with a free-streaming length much larger than a protogalaxy.

So astrophysicists are now contemplating theories in which the unseen mass is a mix of both cold and hot dark matter.

Because hot dark matter is always rushing about, it wipes out details, and does not allow thin delicate structures like those seen in the sky.

Hot dark matter therefore is nowadays always discussed as part of a mixed dark matter theory.

Thus, dark matter made from neutrinos is termed "hot dark matter".

By contrast hot dark matter would smear out the large-scale structure of galaxies and thus is not considered a viable cosmological model.

Let's get out there, where the experiments have a chance to succeed, and measure how much hot dark matter and cold dark matter is around.

Hot dark matter: A rival to the cold dark matter theory to explain the nature of the dark stuff which holds the Universe together.

Hot dark matter may include (massive) neutrinos, but observations imply that only a small fraction of dark matter can be hot.

Recent computer simulations tended to support theories for a mix of cold dark matter with hot dark matter, such as fast-moving particles like neutrinos.

Hot dark matter is a hypothetical form of dark matter which consists of particles that travel with ultrarelativistic velocities.

How much is cold dark matter, how much hot dark matter, how much shadow matter?"
