  • Dark matter - Wikipedia
    In astronomy, dark matter is an invisible and hypothetical form of matter that does not interact with light or other electromagnetic radiation Dark matter is implied by gravitational effects that cannot be explained by general relativity unless more matter is present than can be observed
  • Dark Energy and Dark Matter | Center for Astrophysics | Harvard . . .
    Dark matter makes up most of the mass of galaxies and galaxy clusters, and is responsible for the way galaxies are organized on grand scales Dark energy, meanwhile, is the name we give the mysterious influence driving the accelerated expansion of the universe
  • Dark Matter: The Unseen Force Shaping Our Universe
    Dark matter is one of the most enigmatic and puzzling aspects of modern physics and cosmology While we can observe its gravitational effects on galaxies and other cosmic structures, the actual composition and properties of dark matter remain a mystery
  • What Is Dark Matter? - Science Notes and Projects
    Dark matter is a hypothesized form of matter that does not interact with light or other forms of electromagnetic radiation, but exerts gravitational effects on visible matter, light, and the structure of the universe
  • Dark Matter - MIT Kavli Institute
    The fundamental nature of dark matter remains an outstanding puzzle of astrophysics, cosmology, and particle physics: figuring it out could provide clues to new fundamental particles or principles of physics, or reveal the history of the universe in its first moments
  • What Is Dark Matter? An Introduction to One of Science’s Biggest Mysteries
    At its core, dark matter is a type of material that doesn’t interact with electromagnetic forces—meaning it doesn’t emit or absorb light This lack of interaction with light is why dark matter can’t be seen, making it one of the most challenging subjects in astrophysics
  • Dark Matter - Brown Particle Astrophysics
    A visualization of simulations showing dark matter filaments permeating the universe, providing the necessary gravity to pull matter together and form galaxies
  • Understanding Dark Matter: A Deep Dive - biolecta. com
    What is Dark Matter? Dark matter refers to a type of matter that does not emit light or energy As a result, it cannot be detected directly through existing telescopes or sensors Scientists infer its presence through gravitational effects on visible matter
  • What is Dark Matter? | Axion Dark Matter @ Yale
    First theorized by Swiss astronomer Fritz Zwicky in 1933, dark matter is a solution to many inconsistencies between theoretical and experimental results in astrophysics The strongest of these motivations come from gravitational observations, in which expected mass is much higher than observed mass
  • How Dark Matter Works - HowStuffWorks
    Unlike baryonic matter, dark matter neither emits nor absorbs light or other forms of electromagnetic energy Astronomers know it exists because something in the universe is exerting a significant gravitational pull on things we can see
