Such theories include alternative models of dark energy, such as quintessence, phantom energy and some ideas in brane cosmology; alternative models of dark matter, such as modified Newtonian dynamics; alternatives or extensions to inflation such as chaotic inflation and the ekpyrotic model; and proposals to supplement the universe with a first ...
Much of the genomic dark matter is thought to originate from ancient transposable elements and from other low-complexity repetitive elements. [9] [10] Uncategorized genetic material is found in humans and many other species. [1] [11] Their phylogenetic novelty could indicate the cellular organisms or viruses from which they evolved. [12]
Cold dark matter offers the simplest explanation for most cosmological observations. It is dark matter composed of constituents with an FSL much smaller than a protogalaxy. This is the focus for dark matter research, as hot dark matter does not seem capable of supporting galaxy or galaxy cluster formation, and most particle candidates slowed early.
The only explanation was a large quantity of unseen matter, binding the galaxy together. ... “But the dark matter particle has not been found, even though people looked in all the places where ...
Indirect detection relies on the products of dark matter interactions. Thus, there are several different models of dark matter interactions to consider. Dark matter (DM) is often considered stable, as a lifetime greater than the age of the universe is required ( yrs) for large amounts of DM to be present today. [1]
Dark matter is a mysterious, invisible substance makes up more than 80 percent of all matter in the universe Science has found its first candidate for a dark-matter detector. It’s a really old rock
A WISP (weakly interacting slender particle) is any one of a number of low mass particles that might explain dark matter (such as the axion) A GIMP (gravitationally interacting massive particle) is a particle which provides an alternative explanation of dark matter, instead of the aforementioned WIMP
Comparison of the evolution of the universe under Alfvén–Klein cosmology and the Big Bang theory. [1]Plasma cosmology is a non-standard cosmology whose central postulate is that the dynamics of ionized gases and plasmas play important, if not dominant, roles in the physics of the universe at interstellar and intergalactic scales.
