Dark matter is not known to interact with ordinary baryonic matter and radiation except through gravity, making it difficult to detect in the laboratory. The most prevalent explanation is that dark matter is some as-yet-undiscovered subatomic particle, such as either weakly interacting massive particles (WIMPs) or axions. [16]
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]
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 ...
Dark matter is called ‘dark’ because it’s invisible to us and does not measurably interact with anything other than gravity. It could be interspersed between the atoms that make up the Earth ...
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 may not give off any light or radiation, but we might be able to watch it smash into atoms here on Earth. Dark matter makes up 85% of all matter in the Universe, but astronomers have ...
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.
