1. Learn about the dark matter and its gravitational effects A brief lesson on the gravitational effects of dark matter.
2. Dark matter makes up 30.1 percent of the matter-energy composition of the universe; the rest is dark energy (69.4 percent) and “ordinary” visible matter (0.5 percent).
3. Dark matter Over the course of the 20th century, it became clear that there is much more to the universe than meets the eye.
4. Understand gravitational lenses and the importance of tracking the dark matter A discussion of gravitational lenses and the detection of dark matter in galaxies.
5. Known as dark matter, this bizarre ingredient does not emit light or energy.
6. Support for dark matter has grown since then, and although no solid direct evidence of dark matter has been detected, there have been strong possibilities in recent years.
7. Van Dokkum led a team that identified the galaxy Dragonfly 44 , which is composed almost entirely of dark matter.
8. Dark matter may be made of baryonic or non-baryonic matter.
9. Scientists aren't really sure what dark matter is, and some experts question if it even exists.
10. Dark matter is a mysterious non-luminous substance making up the vast majority of matter in the universe.
11. Though experts have observed the gravitational effects of dark matter for decades, scientists remain baffled as to its true nature.
12. Who discovered dark matter?
13. This strange and unknown matter was called “dark matter” since it is not visible.
14. Unlike normal matter, dark matter does not interact with the electromagnetic force.
15. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter.
16. Dark matter seems to outweigh visible matter roughly six to one, making up about 27% of the universe.
17. Dark matter makes up about 27%.
18. This image shows the distribution of dark matter, galaxies, and hot gas in the core of the merging galaxy cluster Abell 520.
19. The result could present a challenge to basic theories of dark matter.
20. We are much more certain what dark matter is not than we are what it is.
21. For this reason, most experts think that dark matter is abundant in the universe and that it has had a strong influence on its structure and evolution.
22. Current models favor a cold dark matter scenario, in which structures emerge by gradual accumulation of particles.
23. Dark matter accounts for five times as much of the universe as ordinary matter.
24. Despite our lack of knowledge, scientists do have overwhelming indirect evidence for dark matter.
25. For example, scientists can explain how galaxies rotate and how the large-scale structure of the universe forms and evolves by dark matter’s existence.
26. The term dark matter was coined in 1933 by Fritz Zwicky of the California Institute of Technology to describe the unseen matter that must dominate one feature of the universe—the Coma Galaxy Cluster.
27. Dark matter is a hypothetical invisible mass thought to be responsible for adding gravity to galaxies and other bodies.
28. What could dark matter be?
29. In astronomy and cosmology, dark matter is hypothetical matter that is undetectable by its emitted radiation, but whose presence can be inferred from gravitational effects on visible matter.
30. Dark matter is postulated to explain the flat rotation curves of spiral galaxies and other evidence of "missing mass" in the universe.
31. According to present observations of structures larger than galaxies, as well as Big Bang cosmology, dark matter and dark energy account for the vast majority of the mass in the observable universe.
32. Dark matter also plays a central role in structure formation and galaxy evolution, and has measurable effects on the anisotropy of the cosmic microwave background.
33. The label “dark matter” encapsulates our ignorance regarding the nature of most of the matter in the universe.
34. But this “cold dark matter” might actually be a mixture of different particles.
35. Many experiments are searching for the signatures of various types of dark matter, both on the sky and in laboratory experiments, including the Large Hadron Collider.
36. In a 2005 paper, I showed, with Matias Zaldarriaga, that cold dark matter particles could cluster gravitationally on scales down to an Earth mass.
