Dark matter is a hypothetical form of matter thought to
account for approximately 85% of the matter in the
universe. Dark matter is called “dark” because it does not
appear to interact with the electromagnetic field , which
means it does not absorb, reflect, or emit electromagnetic
radiation and is, therefore, difficult to detect. Various
astrophysical observations – including gravitational effects
which cannot be explained by currently accepted theories of
gravity unless more matter is present than can be seen –
imply dark matter’s presence. For this reason, most experts
think that dark matter is abundant in the universe and has
had a strong influence on its structure and evolution. Because no one has directly observed dark matter yet –
assuming it exists – it must barely interact with ordinary
baryonic matter and radiation except through gravity. Dark
matter is thought to be non-baryonic; it may be composed
of some as-yet-undiscovered subatomic particles .[b] The
primary candidate for dark matter is some new kind of
elementary particle that has not yet been discovered, such
as weakly interacting massive particle (WIMPs) or
axions
