Cold dark matter seems to work on the large scale.

Yet there are still many questions that the cold dark matter model does not answer.

They have all the properties associated with cold dark matter.

This has given rise in the last decade to the cold dark matter concept.

As such, it is very difficult to determine what the constituents of cold dark matter are.

These hypothetical particles are known as cold dark matter because they move so slowly.

We must be badly underestimating either the cold dark matter or the hot.

These were the first findings to shake confidence in the validity of the cold dark matter theory.

They were forced to change their thinking because cold dark matter alone was unable to explain the very large structures seen throughout the universe.

This bottom up model of structure formation requires something like cold dark matter to succeed.

The rest is presumably mostly cold dark matter, unknown and so far undetectable.

The desire to make new nontrivial predictions, for example, to provide possible cold dark matter candidates.

Other astrophysicists are not so sure about either the new density measurements or the reality of cold dark matter.

Today, cold dark matter is the simplest explanation for most cosmological observations.

The leading candidate for the dark matter until now, called cold dark matter, is simple.

This matter has two components cold dark matter and dark energy.

The composition of the constituents of cold dark matter is currently unknown.

I would say it's premature to say we must reject cold dark matter."

Cold dark matter, on the other hand, should have formed galaxies on small scales and at a relatively early time.

But other astrophysicists, who had already become skeptical, said the cold dark matter theory was in serious trouble because of the universe's observed large structure.

"Almost everyone agrees that only hot or only cold dark matter can't reproduce the structure we see in the universe," he said.

Over the last two decades, for instance, computer simulations have lent increasing support for the idea of cold dark matter.

Currently, observations suggest that most of the mass in the universe must be composed of cold dark matter.

Cold dark matter - objects with a free-streaming length much smaller than a protogalaxy.

Many simulations simulate only cold dark matter, and thus include only the gravitational force.
