SIFTING THROUGH Nonetheless, theorists who study galaxy formation maintain that the cold dark matter model isn't yet in peril.
In the cold dark matter theory, smaller structures form first, then they merge with each other to form more massive halos, and finally galaxies form within the halos.
Furthermore, several observations hint that the distribution of dark matter in galaxy clusters is spherical rather than football-shaped, as models of cold dark matter suggest.
To circumvent the mismatches, some theorists suggested that particles of cold dark matter interact with each other more strongly than astronomers had proposed.
The leading model presupposes that the universe is filled with an unseen, slowly moving substance called cold dark matter.
Thought to make up as much as 99 percent of the mass of the universe, cold dark matter easily gathers into clumps.
The hypothetical superheavy particle mentioned in the article would be a form of cold dark matter at least 10 trillion times more massive than a proton.
Slow-moving particles, generically known as cold dark matter, are the best candidates for this exotic material, Turner says.
These models assume that most of the matter in the cosmos is composed of invisible, slow-moving material known as cold dark matter and that this material has too low a density to keep the cosmos from expanding forever.
The new simulations follow a type of slow-moving dark matter, cold dark matter, whose ability to gather into clumps is believed to hasten the formation of galaxies.
