Why do astronomers theorize that most of 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

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 do astronomers speculate makes up at least 90 percent of matter in the universe?
Cold dark matter. It can't be seen or detected by its radiation. Some say that ranks it with Bigfoot and the Tooth Fairy!
Where is the largest dark matter in the universe?
Dark matter is everywhere, there really is no place that has the most dark matter.
Is the universe matter?

What is Astronomers have been studying the universe for many years. why don't astronomers know more about out universe if they have been studying it for so long?
Despite many years of study, astronomers face significant challenges in understanding the universe due to its vastness and complexity. The universe is constantly changing, and many phenomena occur over timescales that are difficult to observe. Additionally, much of the universe is made up of dark matter and dark energy, which remain poorly understood. The limitations of current technology and the vast distances involved also hinder our ability to gather comprehensive data.
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 the percentage of dark matter in your universe?
In my Universe, about 23% of its energy is found in dark matter -- about four to five times more than in matter we happen to understand. I don't know the percentage in your Universe.
