The evidence for the existence of dark matter in the universe includes the extra mass of Galactic clusters discovered by Fritz Zwicky, and the spinning galaxies which rotate at the same speed as discovered by Vera Rubin.

Why do astronomers theorize that there is dark energy in the universe?
There are several pieces of evidence for dark matter. For example: * Our galaxy, and many other galaxies, rotate way too fast for the amount of known matter. * Evidence from gravitational lensing.
What evidence is there of existence of dark matter in the galaxies?
The motions indicate a greater gravitation pull than from what we see.
Why do astronomers theorize that most of the matter in galaxies and clusters of galaxies is dark matter?
most of the mass in a cluster of galaxies is invisible, which provides astronomers with the strongest evidence that the universe contains a great amount of DARK MATTER

What evidence is there of the existence of dark matter?
The gravitational effects. For example, gravitational lensing; also, galaxies spin way too fast for the amount of known matter.
Where is the largest dark matter in the universe?
Dark matter is everywhere, there really is no place that has the most dark matter.
Do black holes interact with dark matter?
Important as dark matter is thought to be in the cosmos, direct evidence of its existence and a concrete understanding of its nature have remained elusive. Dark matter is expected to be very pervasive in the cosmos, and pretty much associated with normal matter. The prevailing hypothesis is that dark matter presence is accumulated consistent mass density; i.e. the more mass density, the greater the accumulation of dark matter. Note: Dark matter is hypothesized to play a central role in state-of-the-art modeling of structure formation and galaxy evolution. All these lines of evidence suggest that galaxies, clusters of galaxies, and the universe as a whole contain far more non-baryonic dark matter than normal baryonic matter.
Is the universe matter?
The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.The Universe contains matter, energy, dark matter, dark energy, empty space - and of course, lots of structures made up of those.
The amount of dark matter in the universe important?
Yes it is important because on basis of dark matter amount our universe will expand.
Is there a lot of dark matter in the universe?
Depends what you mean by "a lot." The gravitational effect of dark matter -- whatever the stuff happens to be -- is about six times greater than that of all the visible matter in our Universe.
What is the ultimate matter in the universe?
Black or dark matter
What is dark matter How is it formed?
Dark matter is the term used to describe the hypothetical type of non-baryonic matter rationalized to account for discrepancies between the mass of large astronomical objects, determined from their gravitational effects, and the mass calculated from the "luminous matter" that they contain: i.e. stars, gas and dust. Since there are no empirical evidence to support dark matter, by process of elimination, based in part on the calculations consistent with general relativity, dark matter is estimated to constitute 84.5% of the total matter in the universe. According to the Planck mission team, and based on the standard model of cosmology, the total mass–energy of the universe contains 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy. Although the existence of dark matter is generally accepted by the mainstream scientific community, there is no generally agreed direct detection of it. Other theories including MOND and TeVeS, are some alternative theories of gravity proposed to try to explain the anomalies for which dark matter is intended to account. Due to a lack of empirical evidence, there is are no theoretical conjectures for the formation of dark matteras part ofthe Big Bang event. Other Opinion: From an alternate perspective, dark energy is thought to be the original medium of a pre-Big Bang universe. Consequently the Big Bang creation event, via an unfolding of its condition from singularity, introduce the intrusion of our existence: a reality of positive density matter within a traditional fourth dimensional SpaceTime continuum. Considering a pre-Big Bang universe as zero density matter, the intrusion of positive density matter simultaneously provided for introduction of negative density matter (or dark matter). The resulting effect of bringing the universe back into the more ordered condition consistent with its pre-Big Bang persistence is the expanding of the positive density matter within our fourth dimensional universe.
