Dark Matter

Dark matter

In astronomy and cosmology, dark matter is an invisible and hypothetical form of matter that does not interact with electromagnetic radiation, including light. Dark matter is implied by gravitational effects that cannot be explained by general relativity unless more matter is present than can be observed. Such effects occur in the context of formation and evolution of galaxies, gravitational lensing, the observable universe's current structure, mass position in galactic collisions, the motion of galaxies within galaxy clusters, and cosmic microwave background anisotropies. Dark matter is thought to serve as gravitational scaffolding for cosmic structures. After the Big Bang, dark matter clumped into blobs along narrow filaments with superclusters of galaxies forming a cosmic web at scales on which entire galaxies appear like tiny particles.

Dark Matter (2024 TV series)

Dark Matter is an American science fiction television series created by Blake Crouch, based on his 2016 novel. The series premiered on Apple TV+ on May 8, 2024. In August 2024, the series was renewed for a second season, which premiered on August 28, 2026.

Matter

In physical science, matter is anything that has mass and occupies space by having volume. All everyday objects that can be touched are ultimately composed of atoms, which are made up of interacting subatomic particles. In everyday as well as scientific usage, matter generally includes atoms and anything made up of them, and any particles that act as if they have both rest mass and volume. However it does not include massless particles such as photons, or other energy phenomena or waves such as light or heat. Matter exists in various states. These include classical everyday phases such as solid, liquid, and gas – for example water exists as ice, liquid water, and gaseous steam – but other states are possible, including plasma, Bose–Einstein condensates, fermionic condensates, and quark–gluon plasma.

Darkness

Darkness is the condition resulting from a lack of illumination, or an absence of visible light.

Noun

1. Matter which cannot be detected by its radiation but whose presence is inferred from gravitational effects.
2. Matter which has mass but which does not readily interact with normal matter except through gravitational effects.
