Dark matter is matter of an unknown type. It is known to exist, due to its gravitational influence, but it is not known what it is made of. There is at least 5 times as much dark matter than "normal" matter.
What else can I help you with?
Which is thought to be more prevalent in the universe dark matter or dark energy?
Dark energy. The current estimates for the distribution of mass/energy in the Universe are approximately: 68% dark energy 27% dark matter 5% baryonic (i.e. "normal") 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 is deep in space and has less effect on earth?
Deep in space, dark matter and dark energy are two significant components that have minimal direct effect on Earth. Dark matter, which makes up about 27% of the universe, interacts primarily through gravity, while dark energy, accounting for approximately 68%, drives the universe's accelerated expansion. Both remain largely undetectable and have negligible impact on our planet compared to other cosmic forces. Their existence is inferred through gravitational effects on visible matter and the large-scale structure of the universe.
When was Dark Universe - film - created?
Dark Universe - film - was created in 1993.
What is the ratio of dark matter to ordinary matter in a universe?
We're not certain that "dark matter" even exists, or what the proportions of "normal" to "dark" matter is. I have read some articles saying that the ratio might be as much as 20-1; 20 parts dark matter to one part normal matter, but these are predicated (I believe) solely on rough calculations based on the perceived mass of the galaxy and its apparent rotational speed.There appears to be a great deal of speculation and estimation in these calculations.One important trait of a scientist is to NOT GUESS about things that we don't know, and to admit the boundary between the known, the believed, and the unknown. Even if the current hypotheses about dark matter and dark energy turn out to have some basis in reality, we will certainly be surprised by the truth when we finally learn it.
Whats inside the universe?
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.
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 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.
What is the percentage of dark matter in the 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.
Is dark energy and dark matter killing the universe?
No. What is killing the Universe is the Second Law of Thermodynamics.
What subsystems make up the universe?
It is theorized that dark matter makes up 80 percent of the universe. Another theory is that 68 percent of the universe is dark energy, 27 percent is dark matter, and 5 percent is baryonic matter.
What percentage of the universe is matter?
It is believed that about 4% of the mass in the Universe is normal matter. About 23% is dark matter (matter of unknown composition), the remainder being something even more mysterious called dark energy. I suggest searching the Wikipedia for "dark matter" and "dark energy", for more details about both.
Which is thought to be more prevalent in the universe dark matter or dark energy?
Dark energy. The current estimates for the distribution of mass/energy in the Universe are approximately: 68% dark energy 27% dark matter 5% baryonic (i.e. "normal") matter
